Transcript of Ruredil PBO Data Sheet
DescriptionRUREDIL X MESH GOLD is an innovative Fiber-Reinforced Cementitious Matrix (FRCM) composite system for the repair and strengthening of concrete structures. It comprises of the reinforcing Polyparaphenylene Benzobis Oxazole (PBO) fabric that works as a continuous reinforcement and RUREDIL X MORTAR 750 cement-based adhesive that anchors the PBO fabric to concrete substrate. PBO is a high strength, unidirectional fabric with primary direction of fiber oriented in the 0º direction. RUREDIL X MORTAR 750 is a cement-based adhesive that must be mixed with water in the job site.
Use Provides additional flexural, shear or compressive strength to concrete structural
elements; Supplements cross sectional loss of corroded reinforcing steel; Seismic retrofit .
Applications Interior and exterior; Vertical and overhead; Concrete substrate; Reinforced and pre-stressed concrete;
Product Highlights ICC-ES ESR-2013 listed product; Level of reinforcement is comparable to Fiber Reinforced Polymer that uses carbon
fiber and epoxy resin.: Level of strengthening can be customized through the application of one or more
sheets of PBO Fabric.; Once applied the system does not alter the response to fire of reinforced concrete and
therefore fire protection is not required, even for indoor applications. ; Durable in conditions in conditions of high environmental temperature
since the system is not characterized by glass transition temperature limitations Does not deteriorate when exposed to alkali environment Ca(OH)2 Na(OH) K(OH) at
pH>9.5 . ; Can be applied after rain over damp substrates, which make the composite ideal for
emergency applications; Not affected by moisture, it maintains its performance properties over time in humid
environments;

HOW TO USEDesignRUREDIL X Mesh Gold strengthening system should be designed to meet the specific project design requirements. Ruredil provides engineering exploratory design at no obligation.
InstallationRUREDIL X Mesh Gold must be applied in strict compliance with the installation instructions reported in this Technical Data Guide by trained applicators approved by Ruredil.
Surface Preparation• Concrete must be structurally sound and fully cured (28 days). Surface must be
clean, free of dust, loose parts and without any contaminants, such as paints,
• If a polymer modified cement-based repair products is used, be sure to bring CSP = 5 after curing.
• Always round corners to at least a 1/2 in. radius. Internal corners should be smoothed by troweling.
• Ruredil staff will provide proper specifications and details based on the project requirements.
Mixing• Precondition RUREDIL X MORTAR 750 cement-based adhesive to 70°F (21°C)
before mixing. • Mix in a pail using hand-held slow-speed drill and a paddle pail. Alternatively
use a mortar mixer with a rotating drum. Do not mix by hand.• Pour potable water into mixer. Use a maximum of 1.7 gal (6.3 L) of water
per 55 lb (25 kg) bag of RUREDIL X MORTAR 750. Do not deviate from the recommended water content.
• Add the powder to the water while continuously mixing for a minimum of 2 minutes.
• Add a maximum of 1.5 pint (0.7 L) of water and mix for additional 2 minutes. • Total quantity of water should not exceed 1.9 gal (7 L)• Let the mix rest for 2-3 minutes • Mix again for 2-3 minutes. • RUREDIL X MORTAR 750 should be lump-free before application.
Application• Damp the substrate to Saturated Surface Dry (SSD) condition. In case of high
ambient temperatures and/or low RH, mist the substrate frequently during the application so to prevent early drying out of the adhesive.
• Remove standing water before application.• Cut the PBO fabric as necessary. Use Kevlar shears or an angle grinder with a
diamond cutting disk. For large projects, Ruredil can deliver pre-cut PBO Fabric upon request.
• Apply RUREDIL X MORTAR 750 adhesive over the concrete substrate with a steel trowel at a thin thickness of 1/6 in. (4 mm).
• Lay the PBO fabric with correct fiber orientation over the adhesive and lightly press it into the adhesive. Each sheet of PBO Fabric must be totally encapsulated in the thickness of RUREDIL X MORTAR 750 adhesive.
• If the structural design requires two sheets of PBO Fabric, add a second layer RUREDIL X MORTAR 750 adhesive at 1/8 to 1/6 in (3 to 4 mm) thickness, a second sheet of PBO fabric and embed it into the thickness of the adhesive.
• Repeat the sequence as specified by the designer. Usually RUREDIL X MESH GOLD composite system requires from 1 to 3 sheets of PBO Fabric.
• Complete the installation adding a final layer of RUREDIL X MORTAR 750 adhesive at 1/8 to 1/6 in (3 to 4 mm)thickness so as to encapsulate the final sheet of PBO Fabric.
• Each layer of RUREDIL X MORTAR 750 adhesive must be applied when the previous layer is still wet and has not hardened.
• If the surface of RUREDIL X MORTAR 750 adhesive has hardened, sandblast it before applying a new layer of adhesive.
• PBO Fabric must be lapped 6 inches minimum in the primary direction of fiber orientation. No lapping of the fabric is usually required in the secondary direction.
• RUREDIL X MORTAR 750 must be applied from 40 to 105°F (5 to 40°C). Follow ACI 305 and 306 for application in hot and cold weather.

Figure 1. Beam geometry
A simply supported concrete beam is reinforced with three No. 3 bars in tension and two No. 3 bars in compression. Dimensions and reinforcement details are shown in Figure 1. Effective span of the beam is 60 in. The design compressive strength of concrete is f!! = 5000psi and steel rebars are grade 75. Shear reinforcement of the beam is designed to prevent failure exclusively due to shear. The beam is under-reinforced in accordance with ACI 318-14 guidelines, and meets the minimum reinforcement requirements. Theoretical design capacity of the beam is 19.3 kip-ft.
The following is an example calculation of strengthening the beam with three layers of PBO FRCM according to ACI 549.4R-13 design guidelines. Material characteristics of the FRCM system are obtained through experimental testing per AC434-16. Based on the calculation, three layers of PBO FRCM provide 36% increase in terms of design ultimate capacity (26.3 kip-ft) compared to the unstrengthened beam (19.3 kip-ft).

Mixing Precondition to 70°F (21°C) before mixing. Mix in a pail using hand-held slow-speed drill and a paddle. Alternatively use a mortar
mixer with a rotating drum. Do not mix by hand. Pour potable water into mixer. Use a maximum of 1.7 gal (6.3 L) of water per 55 lb
(25 kg) bag of RUREDIL X MORTAR 750. Do not deviate from the recommended water content.
Add the powder to the water while continuously mixing for a minimum of 2 minutes. Add a maximum of 1.5 pint (0.7 L) of water and mix for 2 minutes. Total quantity of
water should not exceed 1.9 gal (7 L) Let the mix rest for 2-3 minutes Mix again for 2-3 minutes. RUREDIL X MORTAR 750 should be lump-free before application.
Application Damp the substrate to Saturated Surface Dry (SSD) condition. In case of high ambient
temperatures and/or low RH, mist the substrate frequently during the application so to prevent early drying out of the adhesive.
Remove standing water before application. Apply RUREDIL X MORTAR 750 by trowel, preferably using a steel trowel. RUREDIL X
MORTAR 750 cannot be sprayed. Apply XM750 as part of RUREDILX MESH GOLD composite strengthening system
in order to encapsulate PBO fabric and bond it onto the concrete substrate. Be sure to apply XM750 in thin layers not exceeding 1/6 in. (4 mm) thickness. Do not use RUREDIL X MORTAR 750 to repair concrete imperfections deeper than 1/4 in (6.3 mm).
RUREDIL X MORTAR 750 must be applied in the temperature range of 40 to 105°F (5 to 40°C). Follow ACI 305 and 306 for application in hot and cold weather.
CuringIn hot and dry weather conditions and/or in presence of wind, the surface of XM750 adhesive must be protected with CURING S from Ruredil or equivalent product. The curing compound must be suitable for applications on wet hydraulic mortars in order to reduce water evaporation.
Clean upClean tools with water immediately after use. Cured material must be removed mechanically.
Limitations Use RUREDIL X MORTAR 750 as a component of RUREDIL X MESH GOLD. Do not use RUREDIL X MORTAR 750 as a repair mortar. If concrete repair is necessary
before the application of RUREDIL X MESH GOLD strengthening system, repair with a cement-based, not polymer-modified, mortar such as Ruredil EXOCEM FP.
RUREDIL X MORTAR 750 adhesive must be applied in a thin layer, not thicker than 1/6 in. (4 mm).
RUREDIL X MORTAR 750 cannot be sprayed. It can only be applied by trowel. RUREDIL X MORTAR 750 must be protected from rain, even light rain during application. RUREDIL X MORTAR 750 should not be applied in hot temperatures higher than 95°F
(35°C) or with moderate or strong winds Do not add plasticizers, accelerators, retarders, or other additives to RUREDIL X
