To effectively utilize waste glass fiber reinforced plastic (GFRP), we have proposed a process that produces porous glass fiber-reinforced ceramics by mixing crushed GFRP with clay before firing the mixture. In this study, we aimed at developing water-permeable paving blocks that could prevent the inundation of roads caused by sudden heavy rain in urban areas by focusing on recent environmental issues because mixing crushed GFRP with clay enabled us to produce ceramics that possess high permeability and strength. In order to clarify the production conditions of the ceramics which meet both the strength and permeability criterions required for water-permeable paving blocks, various specimens were made by changing the mixing ratio of GFRP with clay, the particle size of GFRP and the firing temperature, using GFRPs containing 40 - 60% glass fiber. Bending strength, compressive strength and permeability tests were then carried out on the samples. The results indicated that in case of using GFRP containing 40% glass fiber, ceramics met the criterions of water-permeable paving blocks when the mixing ratio of GFRP, the particle size and firing temperature were 40%, 0.5 mm or less, and 1,100°C, respectively. In the case of using GFRP containing 60% glass fiber, ceramics met the criterions when each condition was 40%, 0.5 mm or less or 0.5 ~1.0 mm, and 1,100°C, respectively.
