Micro Silica Used In Concrete Has The Follwing Performance:


Strength Economy:

● Increased compressive strength.

● Increased flexural strength.

● Greater strength development.

● Potentially smaller structural section.

● Less rebound & wastage in shortcreting increase productivity.

● Cement replacement opportunities.


Durability General:

● 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
