GB/T 176-2025 Methods for chemical analysis of cement
Abstract
This document describes the determination methods for LOI, SO3, IR, SiO2, Fe2O3, Al2O3, CaO, MgO, TiO2, Cl-, K2O, Na2O, S2-, MnO, P2O5, CO2, ZnO, F-, water-soluble R2O, and cement alkalinity (pH value) in cement. Cement chemical analysis methods are divided into reference methods and substitute methods. If multiple determination methods are provided for the same component, the reference method shall prevail in case of disputes.
This document is applicable to the component detection of silicate-based cements, clinkers, and raw materials.
