SIPOREX is lightweight Autoclaved Aerated Concrete (AAC) which is also called cellular concrete.
is completely cured mix of calcareous materials such as cement and siliceous fine materials such asquartz sand with the addition of water and aluminum powder acting as foaming agent to form ahomogenous cellular structure known as Calcium Silicate Hydrate.
is a high quality structural material, load-bearing and extremely well insulating material due tonumerous tiny non-connecting air bubbles which gives Siporex its incredibly diverse qualities. The highpressure steam-curing in autoclaves achieves a physically and chemically stable product with anaverage density being approximately one fourth of normal concrete.
is produced as blocks and precast reinforced units, i.e., wall panels, lintels and floor/roof slabs forminga complete building system.
has been used on large scale projects such as housings, schools, hospitals, commercial, industrial andgovernment projects under all climatic conditions since the early nineteen thirties worldwide.
is definitely one of the major achievements in the field of construction. It is a revolutionary materialthat offers a unique combination of strength, lightweight, thermal insulation, sound absorption,unsurpassed fire resistance and unprecedented buildability.

1. Introduction
T E C H N I C A L G U I D EA A C B U I L D I N G S Y S T E M
2.1 Manufacturing ProcessSiporex is produced by a highly complex and advanced manufacturing process in our factory under the careful control ofchemists and engineers. Siporex is made either as steel reinforced panels using moulds 6 meters long, 1.5 meters wide and600 mm deep or as non-reinforced blocks using moulds 6 meters long, 1.5 (or 1.2) meters wide and 600 mm deep. Aschematic diagram of manufacturing process is shown on fig. 1.
The basic raw materials are sand, water, aluminum powder and cement. The sandis ground to required fineness in a ball mill before mixing with other raw materialswith water to form slurry to which a trace of aluminum powder is added asexpanding agent.
All Siporex panels are reinforced with steel. Steel coils are straightened, cut andspot-welded into mats, where crossbars provide anchorage to the longitudinalreinforcements. Siporex blocks are not reinforced.
After dipping the welded mats in a homogenized anti-corrosion mix for rustprotection, they are dried and assembled into cages and set accurately in themoulds before the slurry is poured in.
Regulated amount of aluminum powder gives accurate control of density of thefinal product. Moulds are only partly filled with slurry which then expands in acontrolled reaction to fill the moulds.
When the mass is sufficiently hard, the moulds are stripped and the cake is wire-cutto close tolerances into panels and blocks using high-precision cutting technology.These are then steam cured under high pressure in autoclaves for up to 15 hours.
This completes the chemical process, resulting in a unique crystal structure ofcalcium silicate hydrate and ensuring a stable and inert product giving AACoutstanding qualities not found in other products.
After cooling to ambient temperature, the panels are demoulded and milled torequired profile as necessary. All Siporex panels are singled out for proper marking,and if required, dry cut and stacked for further handling and storage. The blocksare demoulded, strapped, marked and stored on wooden pallets.
The finished goods inspection programme ensures the products quality. Thematerial is now ready for loading and delivery.

2.4 Handling, Shipping and Storage
Siporex products are designed to resist normal handling and transport. Siporex blocks should be handled by forklifts and/orcranes with appropriate straps to avoid damage to the material.
Siporex materials are shipped by trucks or flat-bed trailers and can be transported by road, train and by sea for internationalprojects.
They have unlimited storage stability, provided that they are not exposed to extreme conditions. They must be supported byproperly placed bearers and stored in such a way that they cannot absorb water from the ground or be splashed with seawater. Siporex is an inorganic material and is not affected by termites and other insects.
Siporex Blocks
Bundles of blocks (60 cm high) are stored on woodenpallets. Each pallet can be stored with up to 3 bundles ofblocks (180 cm high). At the storage area, the floor shouldbe level to avoid tilting of stocks. Stocks of blocks can easilywithstand 3 pallets with 3 bundles each of Siporex blocks.
Reinforced Panels
On the ground, the stacks of reinforced panels shall besupported by wooden planks, one on each end, placedapproximately one fourth of the length from the ends.In transporting, the stacks are tied by strapping at bothends, protected with plastic angles.

3.1 Benefits of Using Siporex
The manufacturing process as well as the basic ingredients used provides Siporex its unique properties and benefits not found in other traditional building materials and will radically change the construction practices in this industry.
LightweightSiporex weighs less than a quarter compared to conventional concrete. Due to the lightweight property of Siporex, the foundation loads are greatly reduced resulting to big savings in the overall construction cost especially at areas having poor soil bearing capacity. Its light weight also means significant advantage in transportation cost.
Energy EfficientSiporex ensures pleasantly healthy and comfortable room temperature without the need for additional insulation. Its thermal insulation and heat retention offer a good protection against rapid cooling or heating up too much. This means lower power consumption in environmental management system.
Dimensional AccuracyThe production process guarantees the accurate dimensions of the panels and blocks that comprise thebuilding system. This allows for a straight and plumbed walls resulting in less on-site trimmings and reducesthe quantity of mortar and finishing materials required. The dimensional tolerance is ±3mm for thickness &width and ±5mm for length.
WorkabilitySiporex products can be sawn, cut, slot, drilled, chased and nailed with ordinary woodworking tools which makes them easier to install than other building materials. This also simplifies the installation of electro-mechanical services and other utilities, which means more cost savings.
Resistance to FireSiporex is totally inorganic and does not contain any combustible materials, which means it is resistant to fire. A 15 cm thick panel will resist fire for seven life-saving hours. Siporex is ideal for firewall application and as protection for structural steel construction.

T E C H N I C A L G U I D EA A C B U I L D I N G S Y S T E M
3.1 Benefits of Using Siporex
Acoustic InsulationSiporex meets the appropriate standards for sound insulation in house building, which means quieter andmore comfortable interior. In industrial construction, Siporex minimizes industrial noise pollution. The soundabsorption of untreated Siporex surface is better than that of dense concrete.
Non-toxicSiporex itself is ecologically harmless, since it neither contains gases nor fibers, it is neither dangerous to ground- water nor does it releases any radioactive radiation. No pollutants or toxic by-products are produced in the manufacturing process or even when subjected to fire.
DurabilitySiporex products do not contain any organic matter subject to deterioration and will not degrade evenunder severe weather conditions. Structures built several decades ago are still in active use today.
Quake ResistantThe low mass of Siporex results to reduced total dead load of the building and consequently reducing the applied seismic forces to its structure. Structures built in earthquake zones such as Japan & Mexico have shown good resistance to seismic forces in actual practice.
Speedy ConstructionSiporex has all the advantages of a precast system, i.e. eliminates shuttering, wet construction, curing, on-site testing & quality control resulting to reduced overall construction time and cost. It also requires minimal supervision and construction staff.
Pest ResistantSiporex provides airtight interior, does not contain any organic ingredient and makes your home uninviting to pest, insects or rodents.

3.2 Properties of Siporex
3.2.1 WeightSiporex products are supplied with nominal dry density of Siporex products is 550 kg per cubic meter and weigh less thana quarter compared to conventional concrete. Other densities such as 450 or 600 kg per cubic meter can also beproduced upon request. Due to its light weight, the number of trailers required to transport Siporex materials is much lessthan those required to transport conventional precast panels and handling at site can be carried out with ease.
3.2.2 Compressive StrengthSiporex is solid and has a high compressive strength in relation to its weight, which in the aspect of application is verysufficient to take building loads. Siporex achieves its final strength during the autoclaving process. Following are theminimum characteristic strength of Siporex material corresponding to cube specimen and having nominal dry density of550 kg/m3: Compressive strength = 35 kg/cm2
Tensile strength = 20 to 40% of compressive strength Shear strength = 20 to 30% of compressive strength Modulus of elasticity = 16,000 kg/cm2
3.2.3 Thermal ConductivityThe thermal conductivity (“k” value) for completely dry Siporex is 0.144 W/mºC. The air bubbles trapped in Siporex aregiving10 times better insulation properties compared with conventional dense concrete. This is reflected in considerablesavings of electricity consumption and improved indoor comfort. A special independent study conducted by theResearch Institute of the King Fahd University of Petroleum and Minerals confirmed that 63% energy cost saving isachieved when using Siporex material based on a model 2-storey house with 525 m2 gross floor areas.
Other savings are also achieved by replacing a 30-35 cm thick sandwich wall by a single 20 cm thick Siporex wall. Thiswill reduce the size of R.C. beams, columns and foundations and will give more living space. Siporex construction systemis not only ideal for exterior and interior walls, but also for floor and roofs. All these result in a low average thermalconductivity value for whole building surface.
Siporex is the only structural material classified by the Saudi Electricity Company as an insulation material. Siporexqualities not only exceed their rival construction material but far more superior.

3.2 Properties of Siporex
3.2.4 Fire ResistanceSiporex has remarkable fire resistance properties and is non-combustible.Heat migration takes place at a slow rate due to its low thermalconductivity, giving Siporex excellent fire resistance. Water in crystalline formwithin the material acts as a heat sink and the porous structure allows steamto escape without causing surface spalling. The temperature of Siporex islower in Siporex compared to dense concrete, not only on the non-exposedside but also on the side exposed to heat. This fact is vital as it affects theprotection of the reinforcing steel in structural units.
Due to its excellent fire resistance and very positive practical experienceobtained, Siporex panels and blocks had been widely gaining popularity inworldwide construction. In many cases of building fires, the structural parts ofSiporex were able to continue to serve with minor repairs, whichconsiderably reduced the cost of damage caused by the fire.
The following table shows the unsurpassed average fire-ratings of various thicknesses of Siporex walls:
3.2.5 Thermal ExpansionThe thermal expansion of Siporex is of the order of 8x10-6/°C. Expansion coefficient of regular concrete varies betweenabout 4 to 14x10-6/°C depending on the type of aggregate and curing procedure.
Thickness (cm) 10 15 20 25
Fire ratings (hrs) 4 7 7+ 8
3.2.6 Moisture ContentSiporex products have a moisture content of 25 to 40% of its weight when the material is delivered. As with all concreteproducts, Siporex will dry out until it reaches equilibrium with the moisture content of the surrounding air. In this state, itreaches a moisture content of 2% to 6% within one year from erection.
As with all other concrete finishes, slabs and walls should receive protection against water penetration, For external walls,this can be a single decorative coating.
3.2.7 ShrinkageLoss of moisture in AAC results in drying shrinkage. It is determined according to European Standard as the relative lengthchange for specimens at specified moisture contents of 30% and 6% by mass respectively. The average shrinkage for AACis 200x10-6 as compared to 500x10-6 for ordinary concrete. The lower shrinkage for AAC is attributed mainly to the highpressure steam curing (autoclaving) that the fresh material is subjected to during production.

3.2.8 Acoustic PropertiesThe Sound Transmission Class (STC) rating is a single number guide used to rate acoustic barriers according to theireffectiveness in reducing sound transmission. Sound reduction is the ratio of sound energy at its source to that at anyother location expressed as decibels (dB). It is important to note that the scale of decibel is logarithmic, i.e. an increase of10 dB means a reduction of sound to one-tenth, 20 db a reduction to one-hundredth etc. Figure 4 shows some STC ratingsof a few wall constructions consisting of Siporex material.

The unique structure ofSiporex also providessuperior sound absorptionbetter than normalconcrete and is moreapparent at higherfrequencies. This propertyreduces the echo effect(i.e. reflecting sound) inempty rooms.
3.2.9 Specific HeatAt normal equilibrium moisture content, the specific heat is 1.0 – 1.1 kJ/kg°C or about 0.24 – 0.26 kcal/kg°C.
3.2.10 Melting PointSiporex starts to sinter at about 1,000°C and melts at about 1,100 to 1,200°C. Certain physical transformation occurs atthese conditions, therefore, Siporex is not suitable for construction which are going to be exposed to high temperature,e.g. kilns, stoves, chimneys, etc.

3.2 Properties of Siporex
3.2.11 Environmental Exposure of Siporex
Like any other cementitious materials, Siporex is deteriorated by strong acids. Acid salt solutions such as chlorides orsulphates may also degrade Siporex in long term. However, Siporex is normally unaffected by alkaline solutions.
The vital components of Siporex are water insoluble. However, like most concrete building materials, Siporex containssmall amount of water soluble salt which have no influence on the strength and resistance. Under severe conditions, theycan appear on the surface as efflorescence. The formation of efflorescence is mainly a matter of repeated wetting incombination of very bad drying conditions. Under normal drying conditions, it hardly ever occurs.
3.2.12 Airtightness
Even with normal construction procedures, Siporexbuildings have excellent airtightness qualities. Test onAAC buildings measured 1 to 2.5 air changes per hourat a reference pressure of 50 Pa. This comparesfavorably well with other types of construction, suchas concrete block, where normally the average airchange rate at 50 Pa is about 7. (Ref. NPCA , June 26,2000)
3.2.13 Colour, Texture
Siporex is grayish white with even surface.
The pores present in Siporex material can be dividedaccording to size into micropores (< 0.1 mm) andmacropores (0.1 to 1.0 mm). Of the total porosity orpores volume, approximately 35% is micropores andthe remainder 65% is macropores.
At the wire cut surface, the pores are not visible.Milling of the jointing surface after the steam curingmakes the pores visible.

3.2 Properties of Siporex
3.2.14 Reinforcing Steel Properties
Steel reinforcement to be used in Siporex reinforced products shall satisfy the physical requirements of ASTM A615,A82 or A185. Siporex panels are supplied with corrosion protected steel mats. These mats are dipped inhomogenized anti-corrosion mix and allowed to dry under high temperature. The dipping/drying process isduplicated to ensure a double protection against harsh weather condition.

4.1 Wall Panels
4.1.1 Vertical Wall Panels (WV)
WV are reinforced units, for load bearing applications as either external or internalwalls in a wide variety of low and medium rise buildings. They can also be used asnon-load bearing cladding for steel or concrete framed structures. They may havesingle mat or double mat reinforcements depending on the structural requirements.
4.1.2 Horizontal Wall Panels (WH)
Similar to WV, they are also reinforced units with either single or double matreinforcements, but are used in horizontal positions. Applications include: lowparapet, boundary walls, wall claddings to steel or concrete framed structures andfor filling of space between lintels and ceiling. Tongue and groove joints are usuallyprovided for multi-layered WH construction for ease of on-site assembly.
4.1.3 Fluted Wall Panels (WF)
Wall panels are also available with fluted surface as an added feature. They makevery attractive features in building facades used either in small areas such as underwindow openings or as an all-over treatment. Fluted wall panels are also favoritefeatures for boundary walls. Flutes are available in depths of 25 mm or less.
4.1.4 Partition Wall Panels (WP)
These are normally used as non-loadbearing internal partitions withthickness ranging from 10 to 15 cmthick depending on the height ofwall. The flexibility in the design ofpartition wall panels means it can beprovided with central groove toaccept grouting or with standardtongue and groove, increasing theirease of on-site assembly. They aresimply fixed using steel angles or bygrouting where possible inside framedstructures or concrete-shell buildings.

4.3 Floor & Roof Slabs (FS & RS)
4.3.1 Product and Application
Siporex floor/roof slabs are reinforced aerated concrete products which are produced in accordance with internationalstandards. Siporex slabs attain their design strengths during the high-pressure steam curing process in the autoclaves.Thus, after delivery, slabs can be erected immediately within a very short period and ready for occupancy use.
Installation can be done with minimal number of erection crew, light equipments and will not require highly skilledworkers. Shuttering works are eliminated, and finishing works can commence directly, saving time and overall costs.
Siporex slabs can be used both in flat roof areas or sloped roof. They can also be installed with cantilevered ends,produced with special reinforcements. The excellent thermal insulation of Siporex slabs ensures pleasantly healthy andbalanced internal temperature.
The units are milled along their edges to provide tongue & groove and grouting notch on top. The bottom longitudinaledges are preferred to have corner chamfers giving an attractive V-shaped joints pattern on the ceiling. Siporex slabsare also produced in various thickness and spans depending on the required load-bearing capacities. The table shownon Section 4.3.3 gives a guide to the permissible spans of slabs with different design loads of various slab thicknesses.
FS & RS can be used in all types of buildings, e.g. housings, industrial, commercial & educational buildings.

4.4.6 Block Laying
The first course should be laid on cement-mortar bed of thickness about 1 to 3 cm depending on the evenness of the baseand should maintain a correct level for fast installation progress in the following courses. It is recommended to spray themortar face of the block before installation to keep damp at erection time especially during the hot seasons. Afterinstallation, spray with water twice a day for 3 consecutive days for curing of the mortar.
Three types of Mortars can be applied on the succeeding courses:
4.4.6.1 Glue for Siporex (for thin joints)
Pre-mixed mortar – only water is to be added. Thickness of glue should not exceed 3 mm in horizontal and vertical joints in order
to achieve the ideal consumption rate as follows:
• 7 kg/m2 for Siporex blocks 25 cm thick
• 6 kg/m2 for Siporex blocks 20 cm thick
• 5 kg/m2 for Siporex blocks 15 cm thick
4.4.6.2 Ordinary Mortar with Gesol
1:6 Cement : Sand (by volume) respectively in addition to water (with 10% of Gesol). The erection can be carried out normally as
for conventional blocks. (Gesol is a liquid material used as bonding agent and retardant for the mortar especially during hot
weather. Gesol is available at Siporex factory in 25 kg plastic containers).
4.4.6.3 Ordinary Mortar with Lime:
1:1:10 Cement : Lime : Sand (by volume)
4.4.7 Plastering of Siporex Block Wall
Before plastering, dirt and loose particles should be removed from walls. Spray walls with water and follow one of the twomethods mentioned below:
4.4.7.1 Traditional Plastering:
Similar to plastering of conventional block walls with the following mix:
• Splattering (3mm): Use 1 cement : 3 sand mixed with solution of water and Gesol (20% of the volume). Spray with water twice a
day.
• Ordinary Plastering Mortar: (1 – 1.5 cm thick, apply 24 hours after the splattering)
Use 1 cement : 6 sand mixed with solution of water and Gesol (10% of volume).
4.4.7.2 Plastering with Pre-mixed Mortar
Water is added to the pre-mixed plaster supplied in bags of 25 and 50 kgs. Surfaces should be thoroughly cleaned and wetted
without any splattering. Apply plaster directly with a thickness ranging between 0.5 to 1 cm
In both above methods, walls should be watered twice a day after plastering for three consecutive days.

Thereforethe Siporex system offers high degree of flexibility whichcan easily be adapted to various design requirements.Figure 5.1 below shows how the component parts of theSiporex system fits together to form complete structure.
LCC Siporex offers services including technical viability studies ofclient’s projects to Siporex system, quotations, as well asrecommendations on how Siporex can be adapted to theoriginal design of your structure that will fit your project-specificneeds. Figure 5.2 below shows a sample Siporex shop drawingbased on customer’s architectural drawing.
5. Design
T E C H N I C A L G U I D EA A C B U I L D I N G S Y S T E M
Much of the company’s work entails the conversion of client’s original designs from other materials to Siporex system,generally resulting in cost and energy savings. But the best and most economical use of Siporex is produced by designing inthe material from onset.
Optimum results and savings can be obtained through careful design work and meticulous planning before and duringexecution. Before commencing the architectural design for a project, the following guidelines should be noted:
1. The maximum span of Siporex panels is 6.00 meters. This means that the maximum clear span between the load bearingwalls should not exceed 5.85 meters considering 7.5 cm end bearing of floor/roof slabs. The distance between the non-load bearing walls is immaterial. If the clear span is more than 5.85 meters, then steel or concrete beams supported onsteel or concrete columns should be used to support the roof slabs.
2. Upper walls are recommended to be aligned with walls of the lower floor. Walls at upper floor supported directly onSiporex slabs are not allowed. When unsupported walls cannot be avoided, intermediate steel beam can be used orconvert the wall to non-load bearing lightweight dry wall partition, in order to achieve maximum economy.
3. The foundation should be made high enough such that the external wall panels will not absorb moisture from theground.
4. Width of door/window openings are recommended to be limited to the allowable spans shown in Sections 4.2.4 & 4.2.5in order to utilize Siporex lintels and avoid the use of in-situ concrete lintels.
Siporex buildings are designed based on box system principle. Siporex load-bearing walls act as shear walls resisting lateral forces due to wind or seismic loads. The wall panels have grooves along their edges which form joints when erected. These joints receive steel tie bars from the footing and at the top connecting the lower wall with the one above. As they penetrate the ring beam, a strong connection will be provided between the vertical and horizontal structures. These joints (3.3 x 5 cm) are grouted and they are able to transfer shear forces from one panel to the other.
The roof and floor slabs have tongue and groove as well as notch at the top to be reinforced with 8mm diameter bar between spans and grouted with cement-sand mortar (1:3) consequently eliminating differential deflection. Due to the ring and bond beams around the building, all slabs form membrane acting as laterally stiff diaphragms which can transfer lateral forces to the bearing walls .
These constitute the diaphragm action of the Siporex structural system. Lateral forces are distributed in proportion to the moment of inertia of the walls, that is, proportional to their stiffness. Based on actual experiences of actual occurrences in different countries, It has been noted that Siporex buildings are very resistant to earthquake forces.

6.1 Guidelines for Estimating Erection Cost of Siporex Elements
6.1.1 Erection Manpower
Four (4) man-hours per cubic meter of Siporex panels for residentialconstruction is a good average figure. The figures cover erection of thesuperstructure on the prepared foundation base (level tolerance ±1 cm)and include grouting of wall and roof joints as well as repair works to makethe surface ready for application of finishes. The figures also include castingthe normal ring beam behind the rebated wall panel upstand.
6.1.2 Type of Crane & Crane Hours
Mobile telescopic crane 10 to 40 ton rangedepending on the reach is normally needed. Asingle crane with operator can serve twoerection crews at the same time. Crane usagewill be about 0.33 hours per cubic meter ofSiporex elements considering two crews or 0.66hours per cubic meter for one crew.
6.1.3 Cost of Auxiliary Materials and Consumables
SR 30 to 40 per cubic meter of Siporex elements.The figure includes cost of Siporex glue, sand-cement grout, concrete and reinforcements forring beams, plastic wedges, nails and dowel bars.Cost of large beams/columns requiring formworks shall be calculated separately.

6.3 Erection Procedure
6.3.1 R.C. foundation should be cast with a smooth and leveled surface. Thissaves a lot of work in leveling the tops of wall panels later.
6.3.2 Layout of wall panels should be marked on the foundation using chalk linesand ensuring that any overhang has been allowed for on the periphery ofthe foundation.
6.3.3 Steel dowels connecting the wall panels to the foundation are eitherplaced in their positions before casting the foundation or placed in a drilledhole of 4 cm in diameter in the foundation and then grouted. Anotheralternative is to make a hole of 8 mm diameter and fix the steel dowelsusing Hilti C10 epoxy or equivalent. These dowels are placed at each wallpanel joint as indicated on Siporex shop drawings.
6.3.4 Nylon offset lines should be used to ensure outside line of panels ismaintained.
6.3.5 Aluminum straight edge should be set to line and level to inside faceof the wall.
6.3.6 The longest elevation with least number of openings at the farthestreach should be selected for initial installation. This is to maintainsight lines between operator and erector and ensures correct signalscan be given to the crane operator.
6.3.7 Siporex glue mortar is used as a bed for the wall panels. Wedges areused for temporary support of wall panels and allow fine adjustmentfor plumb.
6.3.8 Corner elements are erected first and carefully positioned.Succeeding panels are erected as per mark numbers shown onSiporex shop drawings.

T E C H N I C A L G U I D EA A C B U I L D I N G S Y S T E M
6.3.9 Working with a fixed straight edge for alignment, the wall panels are liftedby a lifting hook, placed in position and checked for plumb. The top edgesare also aligned and are steadied by temporary wall braces at every 3rd or4th panel. Dowels of Ø5 mm x 250 mm long are used as stitches to connectthe top joints between the panels.
6.3.10 The tightly fixed together wall panels are grouted by thoroughly wetting thegrooves with water and then pouring in fluid cement-sand grout (1:3) andthen positioning steel dowels for the next storey panels. Note that Siporexproducts should always be well wetted with water before applying anyother materials (e,g, glue, grout, plaster,…etc.)
6.3.11 Lintels are placed on top of windows and door openings using a lintel grab.They are supported on and connected to the wall panels adjacent to theopenings. Steel dowels are drilled and grouted on top of the lintel prior toinstallation of vertical panels above.
6.3.12 Floor and roof slabs are lifted with a grab andcarefully positioned with specified end bearings onleveled wall panels. Minimum 50 mm side bearing isrequired on walls parallel to the span. Tongue andgroove joint faces provide firm connection betweenthe units which ensures the stability of the building.
6.3.13 The notches formed between the floor or roof slabsare concreted along with the ring/bond beamsafter placing all the connecting and continuity steelbars. Refer to the figure showing the different detailsfor continuity steel bars.
6.3.14 Any damages are repaired and any spacesbetween the panels are filled flush with Siporex glue.After repair and setting of the mortar, the repairedareas and joints are rubbed down with sand paperto give smooth surfaces.

6.4.1 GuidelinesDamage to Siporex panels may be repaired atsite subject to certain limitations. Siporex unitswhich are structurally defective and unfit for thepurpose for which they are designed must notbe repaired but should be rejected andreplaced with sound units.
Broken floor/roof slabs must be rejected. Abroken floor/roof slab is a unit which due tofracture on its lower face (tension side) orthrough breakage and/ or fracturing of thebearing faces at the ends is no longer able tofulfill its structural functions for which it has beendesigned.
Slabs with transverse cracks which extendthrough the thickness of the slab should berejected. Slabs with hair-line cracks which donot penetrate to the tensile reinforcement willnormally be suitable for use.
Damage which exposes extensive parts of thereinforcement should not be repaired. Panelswith major damage to the bearing surfacewhich exposes the cross bars on the tensile steelshould not normally be repaired.
Spalling or peeling-off of fragments to face ofpanel can be repaired if maximum length ofrepair is 30 cm and depth is less than ¼ of thetotal panel thickness. Spalling to edge of panelcan be repaired if maximum dimension of repairis 30 cm and maximum width is 20 cm.
6.4.2 Repairing InstructionSiporex panels should be free from defects which wouldimpair their strength and structural integrity. Slight damagesare normal and can be repaired as per the followinginstructions:
6.4.2.1 Clean the defective surfaces thoroughly with a stiffbrush and remove all dirt and loose material. Wetthoroughly with water using s large brush. If a largepiece has broken-off and the broken-off section isavailable undamaged, the piece can be glued onby applying Gesol to both surfaces and pressingthe broken-off section into the unit to fit.
6.4.2.2 Place a suitable amount of Siporex glue in abucket. Add clean potable water with 10% Gesoland mix thoroughly with a mason’s spoon till a softputty consistency is achieved. Do not mix moremortar than can be consumed before the mortarstarts to set. Do not add water when mortar starts toset in order to restore workable consistency.
6.4.2.3 Deep repairs shall be reinforced with galvanizedcut nails before Siporex glue is applied. ApplySiporex glue to the damaged area with a mason’sspoon. During application, use slightly morematerial than is needed to fill the damaged area.
6.4.2.4 After application, leave the material untouched tillthe mortar starts to harden slightly. Then level with awood float. If necessary apply a small amount ofwater to the surface during leveling. Level bymoving the wood float towards the Siporexmaterial.

8.1 Chases and Penetrations
Small conduits can be chased easily into Siporexwall panels, but cutting of steel bars should beavoided. (refer to Section 3.2.14 for locations ofsteel bars). For large conduits requiring thecutting of the entire width of the wall panel, thecut portion should be filled with concrete andreinforced with steel mesh at both faces.
Large cut-outs and pipe-runs passing through thefloor / roof slabs can beaccommodated duringdesign stage to avoidunplanned cuttings.Panels with large cut-outswill have reinforcementspecially designed aroundthese cut-outs.

9. Finishes
9.1 Internal Walls
Joints between wall panels should be
taped with fiberglass tape. A thin wall
plaster to be applied in two coats gives
a very smooth surface as a base for
painting or wall papering. Where
required, the second coat may be
applied with a textured finish.
9.2 External Walls
Similarly, joints between wall
panels should be taped with
fiberglass tape unless if the joints
are V-grooved. Where Siporex
panels have V-grooved joints, two
coats of paint with textured finish
are recommended.
9.3 Ceiling
Siporex slabs make
attractive ceiling with the
visible V-grooved lines. Paint
applied in two coats will
give a very smooth base for
painting. Where required,
the second coat may be
applied with a texture finish.
Suspended ceiling systems
can also be used which are normal for bathroomareas to conceal waste pipe runs.
9.4 Floors
Compared to cast-in-situ
concrete floors, Siporex
floor slabs provide a
completely dry smooth floor
construction on which
decorative floor finishes of
tiles, parquet, linoleum and
other required finishes are
readily applied.
Various types of finishes used in conventional concrete construction are also applicable to Siporex system. Before applyingfinishes, damages should be repaired and chases or openings should be made good with Siporex glue mortar. Deep holes andchases can be dubbed with ordinary cement-sand mortar (1:6) to within 5 mm from the surface and finished with Siporex glue.
Finishes for Siporex
T E C H N I C A L G U I D EA A C B U I L D I N G S Y S T E M
Special types of commercially available fixings can be used with Siporex structures.
In fixing built-in units and other items; galvanized nails, bolt fastenings and wall plugs are used. Ordinary wire nails should not be usedsince their anchoring ability to Siporex is low. The type of anchoring method to be used depends on the holding capacity required. Themanufacturer’s recommendations should be consulted as to the maximum loads suitable for use with their products. Some of the typesof fixings and anchors suitable for use with Siporex AAC materials are as follows :
10.1 Galvanized Cut Nails
Galvanized Cut Nailscomes in differentlengths and areavailable at our SiporexFactory.
Cut nails are hammereddirectly into Siporex wallsand do not need to bepre-drilled They can beused to fasten light tomoderate weight itemsto Siporex.
10.2 Hilti HGN Anchors
HGN Gas Concrete Anchors, manufactured by Hilti Company isa Cadmium-free Polyamide anchor specially suitable for AACconcrete base. Available in various sizes, it provides highpressure per unit of area, as well as good resistance to turning inthe hole due to its large fins.
10.3 Fischer Anchors
Also available with plastic plugs suitable for light tomedium weight fixings in aerated concrete.
