Supply the microsilica & GGBS

We are one of the biggest supplier for Microsilica(silica fume) and  GGBS in china. They used in concrete. It can improve concrete’s properties such as compressive strength, bond strength, and abrasion resistance; reduces permeability; and therefore helps in protecting reinforcing steel from corrosion.
