Type !IA-Air-entraining cement for the same uses as Type II, where air-entrainment is desired;
Type III-For use when high early strength is desired;
Type /JL4-Air-entraining cement for the same use as Type III, where air-entrainment is desired;
Type JV-For use when low heat of hydration is desired; and
Type V-For use when high sulfate resistance is desired.
Note 1-Some cements are designated with a combined type classification, such as Type 1/11, indicating that the cement meets the requirements of the indicated types and is being offered as suitable for use when either type is desired.
