Composition of cement

Composition of cement. Introduction Lime or calcium oxide, CaO: from limestone, chalk, shells, shale or calcareous rock; Silica, This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 o F). It hydrates rapidly, but does not contribute much to strength of the cement paste.
