Abstract: The brick masonry is used in a wide range as an infill material in reinforced concrete (RC) frames. In general masonry infill (MI) are treated as non-structural elements and ignored in many structural designs, But the contribution of infill under lateral loads shows the better performance and contribution to strength and stiffness of RC frames. The stiffness of masonry controls the failure of MI and plays a significant role under lateral loads. Masonry is a brittle material and exhibits poor performance under shear and flexure. The Geo-fabrics are used as tensile property enhancing materials in many infrastructural works. The prime focus of this work has been focused to make brick masonry to more stiff by compositing the polypropylene geo-fabric at parallel to mortar bed joint and perpendicular to mortar bed joints with the help of cementitious matrix. In this work, 18 numbers of 0.7m×0.7m×0.23m brick masonry wallets (6 wallets conventional + 6 wallets reinforced by PP Geo-fabric parallel to bed joint + 6 wallets reinforced on the face of the wallet with cementitious matrix) are subjected to load bearing test and Diagonal Compression. The experimental results under both the test were compared with normal conventional specimens. The results showed that better performance with PP geo-fabric reinforced specimen compared with conventional masonry wallets.
Keywords: Polypropylene, Shear Strength, Flexural Strength, Stiffness, Diagonal Compression.
