Scope
GB/T 37125-2018 is the English-translated version of 硫铝酸盐水泥熟料.
GB/T 37125-2018 is the Chinese national product standard for sulphoaluminate cement clinker sold as a traded material. It defines the clinker as the product of burning a suitably proportioned raw meal to full or partial melting, with anhydrous calcium sulphoaluminate and dicalcium silicate among its main minerals.
The clinker is graded by its Al2O3 content into three classes, coded SACC-I, SACC-II and SACC-III, and its chemical composition is specified as mass fractions.
The standard also covers the test methods, which draw on the national methods for cement chemical analysis, fineness, specific surface area, setting time and soundness, together with inspection rules, packaging in bags or ton bags, marking, transport and storage. It was issued on 28 December 2018 and has applied since 1 November 2019.
