Definition of Cement Portland cements are hydraulic cements, meaning they react and harden chemically with the addition of water. Cement contains limestone, clay, cement rock and iron ore blended and heated to 1200 to 1500 C. The resulting product clinker is then ground to the consistency of powder. Gypsum is added to control setting time.
