Abstract

An apparatus for producing a building block includes a mould box (13) which can rest on a board (10). Within the mould box is a frame (14) which at its lower and has bars (18). Stops (17) are provided to position the frame relative to the board. A semi-dry mix of material is loaded into the mould box and frame and is compacted using vibration assisted by a tamper plate (22). When compaction is complete the mould box (13) is moved away from the surface of the board so that the lower edge of the mould box lies above the lower edge of the frame. The frame (14) and the tamper plate (22) are then lifted away from the surface and the compacted mass fractures along a plane defined by the bars (18). The board is then removed with the compacted mass which is allowed to cure.
