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.

96% Densified Silica Fume Has the Following Features:

● 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.

(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
