White Silica Fume – the Ultimate Pozzolan (20kg)

White Silica Fume – the Ultimate Pozzolan
MACt is pleased to offer white silica fume for the production of high performance decorative concrete. Trinic have thoroughly evaluated the performance of this product and found it superior to other pozzolans as well as other silica fume products.
We have found it to make extremely workable mixes and create beautiful finishes. It is a must for GFRC or Wet cast mixes.

  • Improves the properties of both fresh and hardened concrete
  • The most important property is its 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
