Abstract: An insert for use in a building block is disclosed. This insert has a substantially serpentine shape, is integral, and contains three substantially T-shaped sections and a multiplicity of curvilinear surfaces. Each of the T-shaped sections is defined by walls which extend continuously and divergingly from the top of the insert to the bottom of the insert.

Abstract: A process for preparing a building block is described. In the first step of the process, an integral, substantially serpentine insert with a density of from about 1 to about 2 pounds per cubic foot is disposed within a mold. Thereafter, a cementitious material is placed in the mold around the insert and then press until the material within the mold has a density of from 80 to 150 pounds per cubic foot. The block thus formed is then removed from the mold and heated at a temperature of from about 75 to about 250 degrees Fahrenheit.

Abstract: An insulated, substantially rectangular building block is disclosed. The block contains two spaced, outer supportive parts which are interlockably connected with each other and which extend along the length of the block; and a curvilinear inner insulating material is present in the space between the supportive parts. Each of the outer supportive parts has a configuration which differs from that of the other such part. The insulating material is wedge-shaped, and it fits into a space between said supportive parts which is defined by walls which extend inwardly from the top of the building block to its bottom.
