The application of our 92% micro silica
鈼?nbsp;Silica fume in Concrete:
- Can increacing strength, density, frost resistance, early strength, abrasion resistance performance, anti-cavitations
鈼?nbsp;Silica fume in Cement:
- Can Strengthen the fibre cement product
鈼?nbsp;Silica fume is used in refractory:
- Can Greatly improve products strength and high temperature performance.
鈼?Other Applications for Silica Fume:
- Rubber industry
- Anti-caking industry
- Pellet binder
- Waterglass industry
According to the SiO2 content, our products can arrange form grade 85% to grade 97%. According to the bulk density, we can divide our products into densified silica fume and undensified silica fume.Micro Silica Fume Admixture Made in China
