Silica fume for large road signs grout

Silica fume for large road signs grout can be used as an additive in the grout used for grouting the base of large street signs to increase the adhesion and other properties of the grout.Silica ash can improve the impermeability and chemical corrosion resistance of the grout, due to the incorporation of silica fume to improve the densification of the grout, greatly reducing the grout voids, effectively preventing the invasion of acid ions and corrosive effects, improve the impermeability of the silica fume grout, chemical corrosion resistance, and corrosion resistance of the steel reinforcement has also been improved.Also it can increased densification, microsilica particles are very fine and can fill in the pores between cement particles.
