silica fume, micro silica, densified silcia, undensified silica

Product Description

Silica fume, also called as micro silica, silica dust, which is a by-product of producing silicon metal or ferrosilicon alloys. Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Because of its fine particles, large surface area, and the high SiO2 content, silica fume is a very reactive pozzolan when used in concrete.

Strength

Increased compressive strength.

Increased flexural strength.

Greater strength development.

Economy

Potentially smaller structural section.

Less rebound & wastage in shorcreting increased productivity.

Cement replacement opportunities.

Durability

Increased concrete density.

Improved impermeability to aggressive agent.

Reduced susceptibility to sulphate attack & alkali-aggregate expansion.

General

Improved cohesiveness reduces segregation & pumpability.

Reduced bleeding allows earlier finishing & efflorescence.

Improved finishing & electrical resistivity.

Due to many benefits imparted to concrete, it is highly recommended for use in the following applications:

Mining & Tunneling.

High rise building.

For producing all concrete products including readymix concrete.

Motoways, bridge, high speed way.

Application:

1) Enhance the mechanical properties of concrete.

High strength and early strength has beenused in substructures of high-performance concrete.

2) Improve the durability of concrete:

Significant improvements can be seen in the permeability resistance, abrasion resistance, anti-corrosion against chlorideion and anti-freezing of concrete.

3) Enhance consructability.

Improve shotconrete, increase easly strength, control temperature contractors can take advantage of the properties of silica fume concrete to expedite projects or to achieve properties that migh otherwise be impossible to achieve.
