GB/T 42531-2023 specifies the definition, composition, technical requirements, and testing methods for low-heat portland slag cement, which is designed to minimize heat generation during hydration. It is primarily applied in mass concrete structures such as dams, large foundations, and bridge piers where controlling thermal cracking is critical. This standard ensures consistent quality and performance in construction projects requiring reduced hydration heat.
