This performance specification covers hydraulic cements for both general and special applications. There are no restrictions on the composition of the cement or its constituents.
This standard classifies hydraulic cement based on specific requirements into 6 types i.e. general (GU), high early strength (HE), moderate sulfate resistance (MS), high sulfate resistance (HS), moderate heat of hydration (MH) and low heat of hydration (LH). Prescribes general requirements e.g. physics properties, packaging, mark and label, sampling and criteria for conformity.
