ABSTRACT:
A ceramic aggregate for concrete is made from a mixture of clay and dried organic garbage in a ratio of about three parts by volume of organic garbage to about one part by volume clay. The mixture is shaped into pancake-shaped pellets and fired at a temperature in excess of the vitrification point of the clay to cause the surface of the pellets to melt and harden the pellets.
