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.
