PURPOSE:To obtain a concrete product which can effectively utilize for the hardened article and has high strength and light weight and is being beautiful in view of decorative performance by setting the hardness of the epoxy resin hard particle to specific value or greater and setting the content of the inorganic filler to a specific weight of the whole of the epoxy resin composition and compounding the hard particles in the concrete. CONSTITUTION:Epoxy resin hard particles are contained in the cement composition containing cement and water so that the Shore hardness becomes 50 or greater. Further, the inorganic fillers are compounded in order to maintain the particle hardness and strength. The content is set to 30-92wt.% of the whole of the epoxy resin composition. Accordingly, the concrete product which has the excellent durability and surface polishing workability and being beautiful decorative effect can be obtained. |
