<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a false stone capable of manufacturing the false stone in large quantities in a short time. <P>SOLUTION: In the manufacturing method of the false stone, at least cement, fine aggregate, rough aggregate and water are kneaded and the kneaded mixture is adjusted in its flowability to form a concrete material 19, which can hold a predetermined shape itself and can suppress the occurrence of internal voids, to dehydrate the same under pressure. Since the concrete material 19 can be held to the predetermined shape itself, the press molding thereof becomes easy. Since the moisture of the concrete material 19 is little, a form 17 can be immediately demolded after press molding and the ageing period of the concrete material 19 can be shortened. By this method, a large quantity of false stones can be manufactured in a short time by one form 17. Since the occurrence of the voids in the concrete material 19 can be suppressed, the false stone of high quality having a dense composition can be manufactured. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
