Zirconium silicon fume for railway bridge concrete

Zirconium silicon fume for railway bridge concrete: This zirconium silica fume is commonly added to concrete used in the construction of railway bridges to reduce the amount of cement in the concrete, eliminate segregation, and improve the corrosion resistance of the steel reinforcement, thus saving costs and improving the quality of the work.Increase early and late strength of concrete Zirconium silicate ash promotes the hydration reaction of concrete, increases its early and late strength and reduces the risk of cracking. Research shows that adding 5% zirconium silicate to concrete can increase the strength of concrete by more than 10%. Improve the impermeability of concrete Zirconium silicate ash fills the microsilica and capillaries in concrete, reducing the permeability of concrete and improving its impermeability. Zirconium silicate zirconium ions can effectively react with calcium oxide in water to generate semi-gelatinous gel, and this semi-gelatinous gel can fill the void…
