ABSTRACT
Recently, the importance of the countermeasures for waste fiber-reinforced plastics (FRP) products has been pointed out, because large quantities of waste FRP products have been discarded. For the purpose of recycling waste FRP products, the present paper deals with the properties of artificial woods (wood-like materials) which are experimentally manufactured by using the FRP powder made by pulverization of waste FRP products. Artificial woods using FRP powder are prepared by autoclaving various cementitious compositions consisting of high-early-strength portland cement, silica fume, FRP powder, shirasu balloon, chemical admixtures, carbon fibers and water, and tested for bulk specific gravity, hardness, flexural and compressive strengths and nail withdrawal. As a result, the optimum mix proportions of the artificial woods are proposed. The bulk specific gravity of an artificial wood with the optimum mix proportions is larger than that of calcium silicate-based wood-like materials, and their flexural and compressive strengths are higher than those of the calcium silicatebased materials. In addition, they can be nailed and sawed like natural wood.
