CL-90 High Density Micro Silica(Densified Silica Fume)
Densified Silica Fume is the most revolutionary concrete additive to have been developed in recent times. 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.

Densified Silica Fume Application:
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.
Due to many benefits imparted to concrete, it is highly recommemded for use in the following application :
– Mining & Tunnelling.
– High rise buildings.
– For producing all concrete products including readymix concrete.
– Motorways, bridges & dams etc
Refractory
High Temperature: Microsilica reacts with alumina forming mullite which gives a castable high strength at up to 1700 degree.
Heat Up: Improved green strength
Flow: Reduced water demand when casting
Dense Castables: Void filling for density for lower permeability, higher strength and higher thermal conductivity
