Research of stress-strain state of basalt fiber polymer rods at adhesive anchoring in concrete

Abstract

The results of experiments to determine the strength and deformability of adhesive anchoring, depending on the depth of embedding basalt fiber polymer rods in the concrete array, are given. The technique of basalt fiber polymer reinforcement preparation for conducting experiments to determine basic longitudinal deformations is fully described. Numerical characteristics of basalt fiber polymer reinforcement for tensile and compression test, to determine bearing capacity in concrete, were obtained. Test methods of adhesive basalt fiber polymer joints are described in detail, as well as research to determine the influence of technological factors on the strength of adhesive bonding, using acrylic modified compositions. Experimental research on the effect of concrete class, adhesive layer thickness and adhesive joint distance from the face of a concrete specimen, on a joint strength, has been performed. The obtained results of experimental research data can be used for attachment joints projecting and industrial technological lines development, as well as for further polymeric adhesive materials, widely applied in industrial and civil engineering, improvement.
