1. Micro Silica Fume Introduction
Micro Silica Fume (scientific name Microsilica or Silica Fume), in the department of smelting ferrosilicon and industrial silicon, through the flue exhaust steam oxidation, specially designed silica dust collector to collect the amorphous powder SiO2. The average particle size of the micro silicon powder is 0.15-0.20μm, Specific surface area is 15000-20000 m2/kg, which has a very strong surface activity. A large number of micro silica is mainly used in cement or concrete admixture, in order to improve the performance of cement or concrete, preparation with high strength (more than C80), wear resistance, erosion resistance, corrosion resistance, anti permeability and frost resistance, early strength special concrete, used for Concrete, Refractory, High Performance Concrete, Oil and Gas Industry, Ceramics, Concrete Roofing, Wall boards, Cementation Repair Products, Concrete Tile & Panels, FCB, Shotcrete, Polymers & Elastomers and (SCC) Self-Compacting Concrete.

3. General advantages
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.

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 in Refractories
● 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.
