WHAT ARE DIFFERENT TYPES OF CEMENT BASED ON ASTM STANDARDS

In this article, we will try to learn about WHAT ARE DIFFERENT TYPES OF CEMENT BASED ON ASTM STANDARDS.

WHAT ARE DIFFERENT TYPES OF CEMENT BASED ON ASTM STANDARDS


ASTM Classification: For general information, it is necessary to see how
Portland cement are 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.
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 (Sulfate Resisting Cement). ASTM standard also have cement of the type IS. This consist of an intimate and uniform blend of Portland Cement of type I and fine granulated slag. The slag content is between 25 and 70 per cent of the weight of Portland Blast-Furnace Slag Cement.

Type IP:
This consist 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 per cent 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 inter ground where air entrainment in concrete is desired.
