ABSTRACT:
A relatively simple, inexpensive building block for use in self-supporting walls includes a rectangular parallelepipedic body formed of a mixture of three parts by weight cement to two parts by weight wood fiber. Vertically extending grooves and in some cases cylindrical holes are provided in the blocks for defining vertical passages extending the height of the wall for receiving reinforcing rods and/or concrete for strengthening the wall.
