Heavy density silica fume for banks cement

Heavy density silica fume banks cement (heavy encrypted silica fume:90% 92% 95% 98%). This encrypted silica fume is commonly used in the cement used in the construction of banks.Reduces Alkali Aggregate Reaction. Silica fume inhibits the alkali aggregate reaction that leads to cracking and failure of concrete by depleting alkali metal ions and forming less soluble compounds. Improves early and late strength. Due to the high activity of silica fume, it promotes the hydration reaction of cement, thus improving the early and late strength of cement. Reduces production cost. Silica fume as an admixture can effectively save resources, reduce cost and pollution. Improve physical properties. As a concrete admixture, silica ash fills the gaps between cement clinker and aggregates, making the concrete structure denser and improving strength and hardness. Its fluidity helps to reduce the pores within the concrete, improving impermeability and crack resistance.
