BONDING OF POLYMER COMPOSITE REINFORCEMENT WITH CEMENT CONCRETE

Abstract

The results of experimental studies of the adhesion of cement concrete of various classes with polymer composite reinforcement (PCA) of fiberglass, having a different type of surface relief of the rods, formed by winding a thin bundle impregnated with a binder, or "sanding" on them, are presented. At the same time, samples of steel reinforcement of a periodic profile A400 and smooth A240 were tested for tearing out of concrete. The dominant role of the adhesion of cement concrete to the surface of the PCA epoxy coating and the insignificant role of spiral winding and "sanding" have been established.
