Title:
MANUFACTURE AND FACILITY OF BUILDING BLOCK IMITATING DRY MASONRY OF STONE
Document Type and Number:
Japanese Patent JPS6392409
Kind Code:
A
Abstract:
A method of manufacturing a building block which imitates a pile of dry stones. According to the method, the stones (10) are placed side-by-side on the bottom of a mold whose inside shape corresponds to the desired block shape, said bottom being constituted by a grating. Cement is then cast inside the mold. The cement (11) is compressed in order to force it to spread out uniformly inside the mold and to creep between the stones (10). While the cement is kept under pressure, water is projected through the bottom grating against the outside face of the block (1), so as to remove any cement which may be found thereon. Pressure is then removed from the cement and it is allowed to set. Finally the block (1) is extracted from the mold.
