ABSTRACT OF THE DISCLOSURE A method for producing concrete products provided with inlaid patterns is disclosed. Such a method comprises a) preparing a reusable mold provided with recessed patterns by applying ultra violet rays on the surface of an ultraviolet- ray setting resin plate, b) preparing a waste mold provided with recessed patterns from the reusable mold, the waste mold being made of a soluble material which can be dissolved by water, solution or heat, c) casting concrete into the waste mold and solidifying the concrete to provide a concrete block on the waste mold, d) dissolving and removing the waste mold from the concrete block and providing recessed patterns on the surface of the concrete block, e) filling a coloring material into the recessed patterns on the surface of the concrete block and solidifying the coloring material, and f) grinding the surface of the concrete block to produce concrete products provided with inlaid patterns on the surface thereof. Due to this construction, the fine and delicate recessed patterns on the original can be accurately and vividly reproduced on the surface of the concrete products as the inlaid patterns.
