How it work
Pozzolonic Effect When water is added to cement, hydration occurs as shown below:
Ordinary Portland Cement (OPC) + H2O â 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 â 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.
