Abstract

The present building block has at least one inner core, a secondary or end core portion, and an interlock protruding from one face and forming a portion of the periphery of at least one of the inner cores. When placed end to end and at the same level, building blocks of the present invention form a secondary core or seat for reception of the interlock. When a first row of building blocks placed end to end is staggered relative to a second row of building blocks placed end to end, the interlocks of one row of building blocks mate with the secondary or end core portions or relatively large inner cores of the other row of building blocks such that neighboring rows of building block interlock. The basic building block has ends that are oblique such that rows having a preset radius can be formed or such that a linear row can be formed by placing one block front-to-back and an adjacent building block back-to-front.
Disclosed are angle blocks with and without splitter wedges, stretcher blocks with and without splitter wedges, blocks for forming corners and posts, cap blocks, and blocks for capping posts.
