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.
Claims6
A method of manufacturing building block imitating a pile of dry stones, the block having a shape and including an outside face which is lined with visible juxtaposed stones held in place by cement, the method comprising the following stages:
- (a) the stones are placed side-by-side on a bottom of a mold whose inside shape corresponds to the shape of the block, the bottom being constituted by a grating;
- (b) the mold is filled with fluid cement;
- (c) the cement is compressed in order to force it to be uniformly distributed within the mold and to creep between the stones;
- (d) while the cement is kept under pressure, water is projected through the bottom grating against the outside face of the block so as to remove any cement to be found thereon;
- (e) pressure is removed from the cement and it is allowed to set;
- and
- (f) the block is extracted from the mold.
