INEDONESIAN PORTLAND CEMENT.

OPC, also known as grey cement, consists of five standard types of cement. Indocement produces OPC Types I, II and V. It is a high quality cement suitable for a wide variety of applications, such as construction of housing, high-rise buildings, bridges and roads. OPC Type II cement has better sulphate resistance and lower heat of hydration properties and is typically used in areas where the soil contains moderate amounts of sulphate and for construction of piers, dams and heavy footings, while Type V provides additional protection against sulphates present in water. OPC Type I is also a raw material for mixed cement, asbestos cement, floor tiles and ferrocement.
