A mould for forming in one step a biaxial concrete masonry (C.M.) block (70 and Figure 2), comprises planar end walls (53a,54), planar top end walls (55), compression and stripper shoe (56) to firstly compress the masonry material then to strip it from the mould downwardly, pallet (60) which is detachable to allow the CM block (70) to be stripped from the mould, and plungers transversely movable in the end walls (53a) for forming apertures in the CM block, the position and number of the said plungers (64,66) being altered in accordance with the shape of the CM block required. After formation of the CM block (70) the plungers (64,66) are moved so as to allow the CM block to be displaced from the mould by the stripping shoe (56) pushing down on the CM block and removable pallet (60). <IMAGE> |
