Abstract

A method for making precast surface stone washing concrete with artistic carving (sculpturing) relief, including the steps of: preparing concrete raw materials to be mixed with water, mold forming and mold removing to obtain the concrete, characterized in that, the mold unit includes an original mold and a forming mold unit, wherein the original mold is a mold unit that can be used repeatedly in carving or sculpturing and have a shaping that is completely identical to the precast surface stone washing concrete with artistic carving (sculpturing) relief to be made. The forming mold unit includes a forming inner mold and a mold unit support, a retaining base (or seat, rack). The forming inner mold is a late ""hell"" mold unit that is formed by directly dipping the carving (sculpturing) original mold into latex for several times, drying to shape and released from the mold. The mold unit support, retaining base (or rack, seat) mainly serves to support or stack and set the latex, pliable forming inner mold in place, and may include: at least two haves of enclosed or hollowed rack-type, detachable and mountable support, retaining base (or seat, rack). After setting the forming inner mold of the forming mold unit in place by means of the mold unit support, retaining base (or seat, rack), the concrete raw materials are then mixed with water, and injected into the forming inner mold. At the time of using stone powder to absorb water in the concrete until solidifying and hardening, the forming mold unit is immediately removed to perform ""stone washing"" by spraying and washing the surface. The product is then set in air to be air dried for one or two days to obtain precast surface stone washing concrete with artistic carving (sculpturing) relief.
