- 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.
