Abstract
A brick comprises a thermoplastic material, such as high density polyethylene (HDPE), and a cement-containing material. The brick may be made by mixing thermoplastic material and dry, uncured cement-containing material. This mixture is placed in a mold. The mold is heated while the mixture is compressed to melt or soften the thermoplastic material and to bind the particulate material in the mold into the shape of a brick. After the hardened brick is removed from the mold, the surface of the brick may be sprayed with water to cure cement-containing material on the surface of the brick.
