Portland Cement (PC) is the name given to a cement obtained by intimately mixing together calcareous & argillaceous, or other silica, alumina and oxides of iron-bearing materials, burning them a clinkering temperature up to about 1450°C, and grinding the resulting clinker to required fineness.

Components of Portland Cement (PC) are as follows:

Portland Clinker : 95-100%

Gypsum : 0-5%
