TYPE I Normal A Portland cement used for general construction, having none of the distinguishing qualities of the other types. TYPE II Moderate A Portland cement having a reduced content of tricalcium aluminate, making it more resistant to sulfates and causing it to generate less heat of hydration: used in general construction where resistance to moderate sulfate action is required or where heat buildup can be damaging, as in the construction of large piers and heavy retaining walls. TYPE III High Early Strength A very finely ground Portland cement having an increased content of tricalcium silicate, causing it to cure faster and gain strength earlier than normal Portland cement: used when the early removal of formwork is desired, or in cold-weather construction to reduce the time required for protection from low temperatures. TYPE IV Low Heat A Portland cement having a reduced content of tricalcium silicate and an increased content of dicalcium silicate, causing it; to generate less heat of hydration than normal Portland cement; used in the construction of massive concrete structures, such as gravity dams, where a large buildup in heat can be damaging. TYPE V Sulfate Resisting A Portland cement having a reduced content of tricalcium aluminate, lessening the need for gypsum, a sulfate normally added to cement to retard its setting time: used where resistance to severe sulfate action is required. Air –Entraining Portland Cement A Type I, Type II, or Type Ill Portland cement to which a small quantity of an air entraining agent has been inter-ground during manufacture; designated by the suffix A, as in Type IA, Type IIA, or Type IllA. White Portland Cement A Portland cement produced from raw materials law in iron oxide and manganese oxide, the substances that give concrete its gray color; used in precast concrete work and in the making of terrazzo, stucco, and tile grout.
