摘要： A lightweight and highly dimensionally accurate molded resin concrete product essentially comprises an intermediate layer composed of resin concrete having a resin content of about 10 to 70%, and a thickness which is not greater than 20/1,000 of its maximum length, and a pair of reinforcing layers composed of a fiber reinforced plastic, and between which the resin concrete layer is sandwiched. The product having a very small wall thickness, and high hot water resistance is particularly useful as a bathtub, or the like. Disclosed also is a method of making such a molded resin concrete product.
