Product Description

Advantage

Higher compressive strength by 10-20 %
Reduces the rate of carbonation
Lower permeability resistance to penetration of water, chloride & other chemicals
Lower free lime formation - delays ettringite and thaumasite formation
Controls bleeding in fresh concrete
Lower Heat of Hydration, which prevents formation of cracks.

How it work

Pozzolonic Effect When water is added to cement, hydration occurs as shown below:

Ordinary Portland Cement (OPC) + H2O CSH (Calcium Silicate Hydrate) + Ca(OH)2(Free Lime)

The free lime does not contribute to strength of concrete. When combined with carbon dioxide, it forms a soluble salt, which leaches through the concrete causing efflorescence, a familiar architectural problem. Concrete is also more vulnerable to chemical attack and deterioration.

When CETEX Microsilica is added, the following reaction takes place:

Ca(OH)₂+ SiO₂ H₂0 + CSH

The reaction reduces the amount of calcium hydroxide in the concrete.

Micro filler effect - It is an extremely fine material, with an average diameter much finer than the cement. It gets well distributed in the cementatious paste, thus blocking the bleed-water channels.
