Silica fume for branch road commercial concrete

Silica fume for branch road commercial concrete (Heavy density silica fume:90% 92% 95%) this microsilica is usually added to the commercial concrete used in the construction of feeder roads to increase the bonding and corrosion resistance of the concrete, among other properties.Improve the impermeability and chemical corrosion resistance of concrete. Due to the incorporation of silica fume improves the compactness of concrete, greatly reduces the concrete voids, effectively prevents the invasion of acid ions and corrosive effect, improves the impermeability and chemical corrosion resistance of silica fume concrete, and also improves the corrosion resistance of steel reinforcement. The effect of silica fume on the frost resistance of concrete. On the effect of silica fume on the frost resistance of concrete, a large number of studies at home and abroad have shown that in the case of equal replacement, the dosage of less than 15% of the silica fume concrete, its frost resistance is…
