      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.
