"Widun" brand low-heat slag silicate grade 32.5 cement is ground with low-heat clinker and a variety of active admixtures. It has moderate early strength, high late strength, strong acid and alkali resistance and strong corrosion resistance. , Due to its low early hydration heat, it is especially suitable for large-volume concrete and dam hydraulic projects, which can significantly reduce the temperature differential stress of concrete caused by the heat release of cement hydration, and cracks generated during concrete construction. Improve the overall concrete durability.
