ABSTRACT:
A modular building block is disclosed as is a mortar and block wall to be formed by a plurality of identical such building blocks stacked in rows in longitudinally overlapping relation with some surfaces of the blocks of one row in abutment with blocks of upper and lower rows, yet with cement mortar of a thickness suitable for a conventional mortar joint between the blocks. Through the provision of spacers of soft material coupled to the blocks, as an integral part thereof, to abut with harder body portions of the other blocks, the blocks can abut each other without interfering with the ability of the cement mortar to bond the blocks together absorbing contractive forces in the walls.
