Description: White silica fume for the production of high performance decorative concrete. This product found to be 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 Replace 5% to 10% of your Portland Cement. This is what we used for our projects. Please consult or use your judgement We have pallet of this product left after using most of it for our project. We are selling almost 50% of our cost. Hope it helps you with your project.
