A Portland cement used for general construction, having none of the distinguishing qualities of the other types.

A portland cement having a reduced content of tricalcium aluminate, making it more resistant to sulfates and causing it to generate less 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.

A very finely 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.

A portland cement having a reduced content of tricalcium silicate and a increased content of dicalcium silicate, causing it; to generate less heat of hydration than normal portland cement; used in construction of massive concrete structures, such as gravity dams, where a large build up in heat can be damaging.

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 resistanceto severe sulfate action is required.
