Silpoz® is a unique product having a combination of Graded and Double Washed / Screened sand with Reactive Pozzolana eventually forming Quality plaster - sand to impart Techno-commercial advantages with great convenience.
During hydration of cement, Free Lime Ca(OH)2 is liberated which combines with CO2 in air to form harmful white crystals of CaCO3, popularly known as Efflorescence: Ca(OH)2 + CO2 = CaCO3 + H2O
The reactive silica in Silpoz® combines with the Free Lime and converts it into useful cemetitious C-S-H gel to reduce the usage of cement and avoid Efflorescence. 3Ca(OH)2 + 2SiO2 = C3S2H3
Free lime Reactive Silica C-S-Hgel
How to use Silpoz®
Mix thoroughly 10 bags of Silpoz ® (40kg each) with 1 bag of cement (preferably OPC 53) and required water (90lit. approx) in a mixer to prepare a plaster mortar.This quantity of material will give a coverage of 185 sq.ft. for a 16mm thick plaster.
We recommend not to store Silpoz® under direct sunlight or rainfall. The packaging material may get damaged due to heat. And, the fines may get washed out if exposed in the rains.
Better workability is guaranteed.
Rich material imparts ease to masons to mix and use without rebound loss.
Thinner plaster guarantees much better coverage and crack-free surface.
No cracks are generated as additives reduce the Hydration Heat of cement.
