Abstract : The present investigation aims to study the feasibility of the application of textile reinforced grids placed in sprayed mortar and to compare its effect on strengthening unreinforced masonry specimens with the technique of manual application of Textile Reinforced Mortar (TRM). The specimens consisted of masonry prisms stacked with nine bricks each; some were reinforced by textile reinforcement placed in sprayed mortar (TRSM) and a few were strengthened with TRM applied by hand. The specimens were subjected to three-point bending. Results showed that the increase in flexural capacity of TRSM samples varied from 35 times to 135 times when compared to the unreinforced specimens. The studied parameters included the mesh size and type of the textile reinforcement, the number of sides reinforced and the number of layers of reinforcement. On the basis of the test results, it is concluded that when the grid spacing is optimum, TRSM is a feasible method for strengthening unreinforced masonry and results in huge savings of time.
