Abstract

A system for making aerated concrete blocks produces such blocks having at least one passageway therein. The system may include a molding station for receiving materials for making aerated concrete and for allowing the materials to rise and stiffen into a body, a dividing station downstream from the molding station for dividing the body into an array of blocks, and a curing station downstream from the dividing station for curing the array of blocks. Moreover, the manufacturing system also preferably includes a drilling station downstream from the curing station to drill the at least one passageway extending through each of the blocks. The passageways provide easier grasping by the mason, reduce the weight without significantly compromising strength, and may be aligned in a wall during construction at a building site to facilitate the placement of vertical reinforcing members in the wall. The drilling station may drill a plurality of spaced apart passageways through each block. In addition, the drilling station may include a plurality of drills, and a positioner for causing relative movement between the drills and a group of blocks to drill the passageways therein.
