Product Description

CETEX MICROSILICA is a super pozzolan - a finely powdered material which when added to cementitious matter increases durability and gives higher strength. It complies with ASTM C1240.

  

ADVANTAGES

  •  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.

 

PROPERTIES

Odour                                                 Odourless

Mean particle size                            25 microns

SiO2 – Silica                                      85 % minimum

Humidity                                            2 % maximum

Loss on ignition at 800°C               4 % maximum

 

 HOW IT WORKS

 1. 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.

 

2. 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.
