ABSTRACT:
Interfitting building blocks are disclosed of both T-shaped and Z-shaped configurations and both blocks define external slots, internal openings and corner bevels for receiving expandable locking elements. The blocks are arranged in a wall in stacked, overlying relationship in horizontal courses of blocks, and the courses of blocks are locked together with U-shaped clips extending between adjacent ones of the blocks in a single course, and vertically extending laterally expandable locking elements extending through adjacent courses of blocks. Mortar is poured down through the aligned openings in the blocks and the locking elements to hold the locking elements in their expanded positions.
