Product Description

Owing to our profound knowledge of this domain, we are able to come up with Micro Silica. It is a finely powdered material, that can be added to cementitious matter. It is known for its resistance to penetration of water, chloride & other chemicals and lower permeability. Micro Silica has content of over 85%, and this complies with ASTM C1240. Apart from this. Other details regarding the offered array are as follows:


  • Lower free lime formation - delays ettringite and thaumasite formation
  • Higher compressive strength by 10-20 %
  • Controls bleeding in fresh concrete
  • Lower Heat of Hydration, which prevents formation of cracks.



  • Odour: Odourless
  • Silica (SiO2): 85 % minimum; mostly 90% +
  • Appearance: Very fine powder
  • Colour: Grey
  • Moisture: 2 % maximum
  • Loss on ignition at 800°C: 4 % maximum.


 1. Pozzolonic effect : When water is added to cement, hydration occurs as shown below:
  • OPC + H2O → CSH (Calcium silicate hydrate) + Ca(OH)2(Free lime)
  • The free lime does not contribute to strength. 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 detoriation. When it is added, the following reaction takes place:
  •  Ca(OH)2 + SiO2 → H20 + CSH
  • The reaction reduces the amount of calcium hydroxide in the concrete.
 2. Micro filler effect : It is an extremely fine material, with an average diameter much finer than cement. It gets well distributed in the paste, thus blocking the bleed-water channels.



  • Available in 20 kg Plastic bag or Jumbo Bag.
