1. Micro Silica Fume Introduction
Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product during silicon and ferrosilicon alloy production.
According to the SiO2 content, our products can arrange form grade 85% to grade 96%. According to the bulk density, we can divide our products into densified silica fume and undensified silica fume.

5. Applications
(1) Silica fume in Concrete
● Increacing strength
● Increasing density
● Frost resistance
● Early strength
● Abrasion resistance performance, anti-cavitations
(2) Silica fume in Cement
● Strengthens the fibre cement product.
● Increases the packing density of the cement matrix.
● Thereby enhance the durability of the fibre cement product.
● Enhances the plasticity of the fresh mix.
● Increases the bending strength of fibre reinforced cement
(3) Silica fume is used in refractory
● Instead of aluminum oxide to be used as refractory material
● As additive in amorphous and shappely refractory products, greatly improved products strength and high temperature performance.
● As casting combination accelerators in integral teeming ladle
● Agglomerating agent, agglutinant, accelerator and additive in other refractory products..
(4) Other Applications for Silica Fume
● Rubber industry
● Anti-caking industry
● Pellet binder
● Waterglass industry
● Shotcrete
● Self-Compacting Concrete
● Mining & Tunnelling.
● High rise buildings.
● For producing all concrete products including readymix concrete.
