PROBLEM TO BE SOLVED: To provide a concrete block production method for producing a projection part to a desired shape, even when there is a cavity in a mold.SOLUTION: A concrete block production method comprises: a holding tool insertion step for inserting a shape holding tool 10 for supporting a cavity, on a position where the cavity is generated in molding recess parts 1h, 2h of a mold 20, in which the mold 20 on which the molding recess parts 1h, 2h for molding a concrete block C are formed, and whose upper face is opened, is used; a material feeding step for feeding a concrete material m to the molding recess parts 1h, 2h; a compression step for compressing the concrete material m; a mold removal step for vertically reversing the mold 20 for upward removing; and a curing step for curing and hardening the concrete block C which is hardened, after the mold removal step. The shape holding tool 10 is inserted into the molding recess parts 1h, 2h of the mold 20 for supporting the cavity, the concrete block C having a desired shape can be produced.SELECTED DRAWING: Figure 1 |
