Application Summary AI generated

GB/T 200-2025 specifies the technical requirements, test methods, and quality control criteria for moderate-heat and low-heat portland cements. It is applied in the construction of massive concrete structures such as dams, large foundations, and bridge piers, where controlling heat generation during hydration is critical to prevent thermal cracking. This standard ensures the cement meets specific heat release limits for durability and structural integrity in large-scale engineering projects.
