<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a concrete molding constituted so as to reduce loads from the aspects of printing and cost when shells are mixed with concrete and using non-ground shells in large quantities. <P>SOLUTION: In the manufacturing method of the concrete molding mixed with non-ground shells, a predetermined form is filled with mortar and, after non-ground shells are uniformly sprinkled over the mortar, the mortar is consolidated under vibration. This operation is repeated a plurality of times to mold the concrete molding. Alternatively, in this manufacturing method, the non-group shells are sprinkled over the inside of the predetermined form or set to the inside of the form and the predetermined form is filled and the mortar is consolidated under vibration to mold the concrete molding. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
