This document summarizes different types of cement products including ordinary Portland cement, Portland pozzolana cement, rapid hardening cement, extra rapid hardening cement, and low heat cement. Ordinary Portland cement is widely used for concrete, mortar, and plaster construction. Portland pozzolana cement has high resistance to chemical assaults and is used in marine structures, sewage works, bridges and dams. Rapid hardening cement gains strength quickly through increased lime content and finer grinding. Extra rapid hardening cement sets even faster than rapid hardening cement through the addition of calcium chloride and is used in cold weather concreting. Low heat cement produced in Malaysia has reduced tricalcium aluminate and increased dicalcium silicate to
