The blocks may be solid, cellular or hollow. Cellular blocks have cavities with one end closed while in hollow blocks the cavities pass through. Lightweight aggregate such as cracked pumice stone is sometimes used. Blocks are made to a number of coordinating sizes, the actual sizes being about 10mm less to allow for the thickness of the mortar.
