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
