1. Micro Silica Fume Introduction
Silica Fume (Microsilica) 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 30m2/g.
Silica Fume (Microsilica) is used in high performance concrete as a Pozzolan to improve its properties.

3. General advantages
● Increased compressive strength.
● Increased flexural strength.
● Greater strength development.
● Potentially smaller structural section.
● Less rebound & wastage in shortcreting increase productivity.
● Cement replacement opportunities.
● Increased concrete density.
● Improved impremeability to agressive agent.
● Reduced susceptibility to sulphate attack & alkali-aggregate expansion.
● Improved cohesiveness reduces segregation & pumpability.
● Reduced bleeding allows early finishing.
● Improved finishing & electrical resistivity.
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.
