White Silica Fume - the Ultimate Pozzolan

We are pleased to offer ORISIL MICRO WHITE SILICA FUME for the production of high performance decorative concrete.  We have thoroughly evaluated the performance of this product and found it superior to other pozzolans as well as other silica fume products.

White Silica Fume improves the properties of both fresh and hardened concrete.

The most important property is the permeability, Lower the ingress of movement of water or chemicals; lower the adverse reactions such as sulfate attack, The reaction between silica fume and the calcium hydroxide, released as the cement hydrates, provides a dense impermeable pore structure.

Improve the mechanical performances of concrete.

The Silica fume reacts with the cement paste to form additional strong Calcium Silicate Hydrate (CSH) providing higher strength.

Silica fume reduces bleeding and enhances the cement paste bond to the aggregates. Thanks to its pozzolanic effect (reaction with Ca(OH)2 ), and therefore to the strength improvement.

Recommended Dosage:  Replace 5% to *0% of your Portland Cement

Silica fume is the most powerful pozzolan available. The particle size is **0 times small than cement and other pozzolans such as VCAS, Slag, or Bottle Pozz.

The increased water demand was minimal with the Silica Fume we tested

• 5% cement replacement is adequate for most mixes with diminishing returns as you approach *0% cement replacement.
• There was no loss of next day strength that occurs with other pozzolans.
• By incorporating We are Stage 2 accelerator in the mixes we were able to exceed 7,**0 PSI overnight with minimal heat.
• Mixes in excess of *0,**0 PSI are easily possible with *5,**0 PSI concrete within the reach of every fabricator.
• The increased density and lower calcium hydroxide of silica fume mixes enhance the performance of We are SB Sealer, more tests to follow.
