ASTM Classification
Before we discuss the above cement, for general information, it is necessary to see how Portland cement is classified under the ASTM (American Society for Testing Materials) standards. As per ASTM, cement is designated as Type I, Type II, Type III, Type IV, Type V and other minor types like Type IS, Type IP, and Type IA IIA and IIIA, etc.
Type I
For use in general concrete construction where the special properties specified for Types II, III, IV, and V are not required (Ordinary Portland Cement).
Type II
For use in general concrete construction exposed to moderate sulfate action, or where moderate heat of hydration is required.
Type III
For use when high early strength is required (Rapid Hardening Cement).
Type IV
For use when low heat of hydration is required (Low Heat Cement).
Type V
For use when high sulfate resistance is required (Sulphate Resisting Cement).
ASTM standards also have a cement of the type IS. This consists of an intimate and uniform blend of Portland Cement of type I and finely granulated slag. The slag content is between 25 and 70 percent of the weight of Portland Blast-Furnace Slag Cement.
Type IP
This consists of an intimate and uniform blend of Portland Cement (or Portland Blast Furnace Slag Cement) and fine pozzolana in which the pozzolana content is between 15 and 40 percent of the weight of the total cement.
Type IA, IIA, and IIIA
These are type I, II, or III cement in which air-entraining agent is underground where air-entrainment in concrete is desired.
