1. Description
RUREDIL 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 USE
Design
RUREDIL X Mesh Gold strengthening system should be designed to meet the
specific project design requirements. Ruredil provides engineering exploratory
design at no obligation.
Installation
RUREDIL 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
• Concretemustbestructurallysoundandfullycured(28days).Surfacemustbe
clean, free of dust, loose parts and without any contaminants, such as paints,

4. • 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
ambienttemperaturesand/orlowRH,mistthesubstratefrequentlyduringthe
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
diamondcuttingdisk.Forlargeprojects,Ruredilcandeliverpre-cutPBOFabric
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
pressitintotheadhesive.EachsheetofPBOFabricmustbetotallyencapsulated
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.

7. 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).

17. Description
RUREDIL X MORTAR 750 is a cement-based adhesive for bonding Polyparaphenylene
Benzobis Oxazole (PBO) fabric onto concrete surfaces. It is designed for exclusive use with
RUREDIL X MESH GOLDcomposite strengthening system. Silicates present in RUREDIL
X MORTAR 750 formulation combine with nitrogen and oxygen atoms of PBO fabric to
create both a chemical and mechanical bond between the fabric and the adhesive.
RUREDIL X MORTAR 750 is easy to apply by hand even in challenging conditions due to
its high workability. It is safe for applicators with no offensive odors.
Use
RUREDIL X MORTAR 750 cement-based adhesive combines with PBO fabric to provide
RUREDIL X MESH GOLDcomposite system for the strengthening of structural elements of
concrete structures, both steel reinforced and prestressed.
Applications
Concrete substrate;
Interior and exterior;
Vertical and overhead;
Product Highlights
Easy to apply by trowel for vertical and overhead applications;
Only requires potable clean water for mixing:
Can be mixed with a slow-speed drill and paddle or mortar mixer.;
Can be applied on damp surfaces as long as there is no standing water ;
Does not alter the response structural elements to fire thus allowing indoor
applications of RUREDIL X MESH GOLD composite strengthening system without fire
protection
Not affected by salt water ;
Water vapor permeable.;
Very limited, if no shrinkage.
Resistant to freeze-thaw cycles.;
RUREDIL X MORTAR 750 adhesive has similar compressive strength/modulus of
elasticity as ordinary concrete, thus facilitating stress-strain transfer between the
adhesive and the substrate.;
100% solvent free.

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.
Curing
In 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.
