This specification covers eight types of portland cement: type I, type IA, type II, type IIA, type III, type IIIA, type IV, and type V. The cement covered by this specification shall only contain the following ingredients: portland cement clinker; water or calcium sulfate, or both; limestone; processing additions; and air-entraining addition for air-entraining portland cement. Portland cement of each of the eight types must have the following chemical compositions: aluminum oxide, ferric oxide, magnesium oxide, sulfur trioxide, tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminofernite. Applicable properties enumerated in this specification will be determined by the following test methods: air content of mortar, chemical analysis, strength, false set, fineness by air permeability, fineness by turbidimeter, heat of hydration, autoclave expansion, time of setting by gillmore needles, time of setting by vicat needles, sulfate resistance, calcium sulfate, and compressive strength. The cement shall be stored in such a manner as to permit easy access for proper inspection and identification of each shipment, and in a suitable weather-tight building that will protect the cement from dampness and minimize warehouse set.
