ABSTRACT:
Apparatus and methods are disclosed for making masonry blocks with one or more surfaces having a roughened texture resembling that of a split block or natural stone. In one embodiment, a mold comprises a plurality of walls defining at least one mold cavity adapted to receive block-forming material. The mold defines an opening through which a formed, uncured block may be removed from the mold. At least one wall of the mold has a plurality of projections extending into the mold cavity so as to contact an adjacent surface of the uncured block in the mold cavity. The projections are positioned such that when the uncured block is removed from the mold, the projections texture the adjacent surface of the uncured block.
