Textile reinforced cementitious composite board was produced using a sprinkling water hardening technique. Test measured the effect of the textile ratio and textile location on the flexural performance of the board. The results show that the flexural behavior of the board made with the sprinkling water hardening technique was greatly improved by adding the glass fibers. As the textile ratio increases, the flexural strength and ultimate deflection of the textile glass reinforced cementitious board are greatly increased. The flexural strength of boards with 1.0% textile ratio can reach 10.64 MPa, which is 3 times higher than the boards without textiles, and the ultimate deflection is 6.74 mm, which is 8 times higher than that of the boards without textiles. The sprinkling water hardening technique may solve construction problems where there is no way to directly mix cement with water.
