COLLOIDAL SILICA CEMENT COLLOIDAL SILICA is at the heart of Lythic technology. It is a substance that reacts with the chemistry of concrete to produce more cementitious material, translating into denser concrete with greater strength. Concrete is a mixture of Portland cement, water and aggregate. Water reacts with Portland cement cement

Silica fume is a byproduct in the carbothermic reduction of highpurity quartz with carbonaceous materials like coal, coke, woodchips, in electric arc furnaces in the production of silicon and ferrosilicon alloys. Applications Concrete. Because of its extreme fineness and high silica content, silica fume is a very effective pozzolanic material.
