of hard rock or where the rock after dressing and exposure will not permanently with stand

and effect or weather, such inferior stone or soft material or loose rock shall be excavated

to an approved depth and the resulting space built up with masonry or concrete so as to

ensure a solid uniformly battered face.

Where soft and unsuitable material is encountered in cuttings at formation level or

immediately thereunder it shall be excavated to such levels directed by the

Engineer/Architect. The resultant excavation shall be filled with suitable materials and

compacted as specified in Clause 2.9.

14.4 Workmanship :-

14.4.1 Plain cement Concrete Flooring :-

Generally workmanship shall conform to IS 2571 code of practice for – laying in-situ

concrete floors. If the floor finish is to be laid over consolidated ground or a layer of hard

core, cement concrete of proportion 1:4:8 or 1:5:10 shall be poured as a base layer to the

thickness indicated on the drawings. In the case of structural slabs, the slab itself will form

the required base.

The area requiring finish shall be divided into suitable panels so as to reduce the risk of

cracking. No dimension of a panel shall exceed 4min case of floor finish laid

monolithically with base concrete and 2m in case of floor finish laid separately on a

hardened base length of a panel shall not exceed 1 ½ its breadth.

Paneling shall be done by fixing timber or steel strips of depth equal to the combined

thickness of base concrete and topping. Before being fixed in position these strips shall be

coated with a thickness coat of time wash. Flooring shall be laid in alternative panels, the

intermediate panels being filled in after one of to days. However, if glass or aluminum

strips are specified for effective separation of panels, the base concrete and toping may be

laid simultaneously in all the panels.

Floor finish laid monolithically with base concrete :-

The sub base shall be properly wetted and divided into panels. The base concrete shall be

poured and tamped and screened to levels suitable to accommodate the topping and given

the desired slope. The surface shall be left rough to provide bond with the topping.

On the green surface of the base concrete topping shall be placed in position as soon as the

base has stiffened enough to allow workmen to tread over it by placing planks. The mix for

the topping shall be as shown in drawing and as stiff as possibly consistent with

workability so as to prevent accumulation of excess water on ???? should any water rise to

surface during compaction and screening, it shall be mopped up. The topping shall then the

floated with the wooden float to under the surface.

Floor finish laid separately on hardened concrete base.:-

The sub base shall be properly wetted and the base concrete laid, if possible over the whole

area at a stretch. The surface shall be left rough to provide adequate bond for the topping

by wire brushing two to three hours after its laying.

Before the topping is laid., the surface of the base shall be thoroughly cleaned of loose

materials, dirt and laitance by wire brushing. Where this is not possible, chipping or

hacking shall be done. The surface shall be soaked with water for 12 hours before laying

the topping. The surplus water shall be mopped up, cement slurry spread and then the

concrete for the topping deposited in suitably divided panels. The mix for the topping shall


118

be as indicated in drawing and as stiff as possible consistent with workability so as to

prevent accumulation of excess water laitance. After thorough consolidation the topping

shall be struck off level and surface floated with a wooden float. Is shall be tested with a

straight edge and mason`s spirit level to detect any inequalities and may undulations found

shall be made good immediately.

14.5 Laying toppings in two layers. :-

Where it has been specified that the topping is to be laid in two layers to obtain very

smooth and dense finish, the base concrete and under-layer of topping shall be laid as

above with the exception that the surface of the finished smooth but left rough after

tamping and leveling.

The top 15mm thick wearing of mix1:2 to 3 cement concrete of consistency stiffer than

that of under-layer of concrete shall then immediately laid over the rough but green surface

of under-layer and thoroughly temped, struck off level and the surface floated with the

wooden float. The surface shall then be tested with a straight edge and mason`s spirit level

to detect any undulations. If any these shall be made good and then the surface finished

smooth as under.

14.6 Finishing the surfaces :

After the concrete has slightly hardened it shall be finished by trowelling or floating.

Finishing operations shall start shortly after the compaction of concrete and shall be spread

over a period of one to six hours depending upon temperature and atmospheric conditions.

The surface shall be trowelled three times at intervals so as to produce a uniform and hard

surface. Immediately after laying only just sufficient trowelling shall be done to give a

level surface. Sometime after the first trowelling, the duration being guided by temperature

and rate of setting of cement, the surface shall be retrowelled to close any pores in the

surface and to draw out and mop up any excess water in concrete or laitance. The final

trowelling shall be done well before the concrete has become too hard but at such a time

that considerable pressure is required to make any impression on the surface. Trowelling of

a dry cement mix on the surface shall not be permitted.

14.7 Curing

As soon as the surface has hardened beyond damage, it shall be kept continually moist for

at least 15 days by impounding water on it.

14.8 Polishing

The floor shall be polished with machine eight weeks after laying when the floor is

sufficiently matured by expert trained polishers. The floor shall than be sprinkled with zine

or tin oxide and rubbed hard with rags. The final polish shall be done with wax or with

patent polish.

14.9 Coloured Cement Concrete Flooring

Where coloured finish is finish is indicated, the top shall be finished with coloured cement

as specified. If coloured cement is not available, the pigment shall be mixed in the

proportion, one part of pigment with three parts of cement.


119

The colouring material and cement shall first be mixed dry. Special attention shall be paid

to the mixing of colour, which should be screened twice with a final screen and again

through final muslin before use. All the colour required for one room shall be mixed in one

lot. For red colour the mixture shall consist of one part of iron oxide to three parts of

cement. For green the colour mixture shall consist of one part of chromium oxide to 3 parts

of cement. After dry mixing, the minimum quantity of water required for workability shall

be added gradually until a paste of the required consistency is obtained. Dry colour shall

not be used to finish the surface of coloured concrete floor. Coloured paste shall be applied

with wooden floating boards and English trowels. 0.06 cu.m. of colour mixture shall be

used for 10 sq.m. of surface.

Any cracks, ruts, disfiguration or discolouring of surface shall be made good without extra

charge. The finished portion of the floor shall be kept wet for at least 15 days.

Coloured concrete shall be polished with Nos. 1, 2 and 3 polishing stones. After rubbing

with these stones, the surface shall be sprinkled with zinc or tin oxide and rubbed hard with

rags. The final polish shall be done with wax or with patent polish. For light colours,

celluloid trowels made by fixing a sheet of celluloid on a wooden trowel may be used.

Before fixing tiles on brick or concrete wall, the wall surface shall first be wetted with

clean water. Thereafter it shall be evenly and uniformly covered with a coating of lime

mortar about 20mm thick before the cushioning mortar has hardened, the back of each tiles

to be fixed shall be covered with a thin layer of neat cement paste and te tile shall be gently

tapped against the wall with a wooden mallet. The fixing shall be done from the bottom of

the wall upwards. Each tile shall be fixed as close as possible to the one adjoining, and any

difference in the thickness of the tiles shall be evened out in the cushioning mortar or

cement paste so that all he tile faces are set in conformity with one another.

Skirting and ado shall be ground and polished just as for floor work but by machine

suitable for he purpose. Skirting and dado may also be polished by hand by rubbing down

with suitable polishing stone evenly and without scratching the surface.

Upon completion of tiling work, it shall be thoroughly cleaned with water using a

scrubbing brush, coarse cloth or broom. Acids, harsh abrasive cleaning powders or steel
