As a recycling technique for the waste GFRP, authors have proposed the manufacturing process of the porous glass fiber reinforced tile by mixing the clay and the crushed waste GFRP and by firing the mixture. In this paper, the influence of the particle size of GFRP on properties of tiles produced by the proposed process was investigated. First, several types of tiles were produced by changing the particle size of the crushed GFRP, the mixing ratio of the GFRP and clay, and the firing temperatures. Then the density, water absorption and bending strength of the specimens were examined by the experiment. From obtained results, it was found that the bending strength of tiles was higher, as the particle size of the GFRP was smaller, and that the effect the particle size of the GFRP on bending strength of tiles was bigger, as the firing temperature was higher. It was also found that the mixing ratio of the GFRP and clay and the firing temperature greatly affected the water absorption of tiles, and the particle size of the GFRP was not effective for the water absorption. It was demonstrated that tiles with both the high strength and water absorption could be made when GFRP with the particle size of 1mm or less was used and the firing temperature was over 1000 degrees.
