Why Colloidal Silica is better for your concrete - EBOSS

Why Colloidal Silica is better for your concrete - EBOSS

Why Colloidal Silica is better for your Concrete Silica is one of the two main ingredients in portland cement. Siliceous clay is mixed with limestone (calcium carbonate) under high heat to make cement. The carbon is driven off by the heat, so the two main ingredients that remain are hard substances, calcium and silicon.
