This document defines the specifications and constituents of 27 common cements, 7 sulfate-resistant common cements, 3 blast-furnace cements with low early strength, and 2 sulfate-resistant cements of the latter type. It specifies the proportions in which the constituents are combined for nine strength classes, as well as the requirements applicable to the constituents and the mechanical, physical, and chemical requirements.
