Cementitious Matrix is Used to Bond High-Strength Polymeric Mesh to Concrete and Masonry, Fallis

Fiber-reinforced polymer (FRP) systems are now widely used for retrofit and repair of concrete and masonry.  The development of these systems has allowed repair and strengthening projects to be performed that, in the past, would not have been possible. Their benefits are well known and include a high ratio of strength to added weight, high durability, and ease and flexibility of installation.

FRP systems, however, are not without their drawbacks.  Recently, Ruredil introduced a new fiber-reinforcement system that maintains the benefits of traditional FRP systems while overcoming some of their drawbacks.  This product consists of a polyparaphenylene benzobisoxazole (PBO) mesh (Ruredil X Mesh Gold) and a stabilized, inorganic, cementitious mortar matrix (Ruredil X Mesh M750) designed to connect the mesh to concrete and masonry substrates. The unique structure of the PBO fiber allows it to bond directly to the mortar matrix, eliminating the need for an epoxy resin to bond the fiber to the concrete or masonry substrate.  (read more)
