Silica Fume White Z3-95

Silica Fume White Z3-95

  • $14200


White Silica Fume Z3-95 comes in 55lb bags. It is improves the properties of both fresh and hardened concrete.

More fume expected the first week of December. Unfortunately, due to an large increase in cost from our supplier, we have had to increase the price of the fume.

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 10% of your Portland Cement

Advantages of Using Silica Fume
