This paper aims to experimentally evaluate the effect of the compressive strength of mortar on the tensile behavior of textile reinforced concrete (TRC) specimens applied the developed grid-type carbon fiber reinforced polymer (CFRP) reinforcement (hereafter referred to as carbon grid), K-Carbon as reinforcement. The experimental results showed that the higher compressive strength of mortar could be effective for the tensile behavior of a TRC specimen reinforced with carbon grid in terms of crack formation and strength. The tensile performance of carbon grid was also revealed to be increased with increasing compressive strength of mortar, but the tensile strength of all carbon grids placed on the specimens was less than 0.5 times the tensile strength of the carbon grids because of the local stress concentration acting on the carbon grids and the silp with mortar. On the other hand, the tensile stress-strain relationship of TRC specimens was idealized as a simple bilinear curve with a bend-over point corresponding to the initial cracking point, and the idealized bilinear curve was revealed to generally illustrate the tensile stress-strain relationship of TRC specimens.
