Heavy density silica fume for office space cement

heavy density silica fume for office space cement(90% 92% 95% 98%)This Microsilica is commonly added to cement used in the construction of office buildings to increase the strength and other properties of the cement.

Silica Fume, when added to cement, can fill the pores between cement particles, making the cement mortar and the hardened product denser;
silica fume can react with the hydration products of cement to generate gel by secondary hydration reaction, and also react with magnesium oxide, an alkaline material in cement, to generate gel, thus improving the early and late hardness of cement;
Due to the reaction between silica fume and alkaline materials, the alkaline materials in cement are reduced significantly, which can reduce the alkaline aggregate reaction of cement and concrete;
Silica fume makes the cement denser, which can improve the impermeability, carbonation and frost resistance as well as the durability of the cement or cement concrete.
