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.
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..
(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
