Type II—For general use, more especially when moderate sulfate resistance is desired;
Type IIA—Air-entraining cement for the same uses as Type II, where air entrainment is desired;
Type II(MH)—For general use, more especially when moderate heat of hydration and moderate sulfate resistance are desired;
Type II(MH)A—Air-entraining cement for the same uses as Type II(MH), where air entrainment is desired;
Type III—For use when high early strength is desired;
Type IIIA—Air-entraining cement for the same use as Type III, where air entrainment is desired;
Type IV—For use when low heat of hydration is desired; and
