Abstract
A construction block comprising a generally rectangular hollow body having a pair of faces joined by side edges. There are spacing flanges extending about the side edges around the perimeter of the block adjacent and essentially parallel to the faces to ensure correct spacing of the blocks when arranged in a wall construction. Cavities for connecting adjacent blocks together are provided at each corner of the block. There is a spanning member having ends adapted for engagement in the cavities of adjacent blocks in order to connect blocks into a unified wall structure.
