Portland cement

Portland cement

A calcium-aluminum silicate produced by fusing or clinkering limestone and clay in a kiln so as to drive off carbon dioxide and produce an oxide glass. The clinker is ground very fine and, when mixed with water, will recrystallize and set. It is combined with aggregate to form concrete. The name is from a resemblance to the Portland limestone of England.
