1. Micro Silica Fume Introduction
Microsilica ( Silica Fume) is a co-product from the production of silicon or ferrosilicon metal. Silica fume is a mineral admixture, a very fine powder of spherical particles that average 0.1 to 0.3 microns in diameter with a surface area of 17 to 30 m2/g.
94% Undensified Microsilica (Silica Fume Grade 94) with Minimum SiO2 Content 94%, grey or gray – white powder, and the refractoriness is >1600℃.

3. General advantages
(1). Silica fume in Concrete
● Can increacing strength, density
● Frost resistance, Early strength,
● Abrasion resistance performance
● Anti-cavitations
(2). Silica fume in Cement
● Strengthens the fibre cement product
(3) Silica fume is used in refractory
● Greatly improved products strength and high temperature performance.
4. Package
25kg/plastic bag, 950kg/jumbo bag,1000kg/jumbo bag.
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.
● Motorways, bridges & dams etc.
