Scope
This document specifies the components, designations, and material requirements of gypsum slag cement, its strength grades, technical requirements, test methods, inspection rules, and packaging, marking, transportation, and storage. This document is applicable to the production, inspection, and acceptance of gypsum slag cement. Gypsum slag cement can be used in large-scale concrete projects underground and underwater, as well as in the preparation of precast concrete components under steam curing conditions. However, it is not suitable for projects with high early-age strength requirements or those subject to freeze-thaw and alternating wet-dry cycles.
