Characterization of New Composite Materials for Masonry Rehabilitation

Article Preview

Abstract:

The purpose of this paper is to provide a better understanding of mechanical behavior of the SRG for strengthening of masonry and concrete structural members. Four SRG material systems were investigated to determine ultimate tensile stress and strain along with the moduli of elasticity of each system as well as compressive strength of the matrix mortars.Based on the test results, SRG composites can be considered as a solution for strengthening or rehabilitation of existing masonry structures.
