How Does Silica Fume Work in Concrete?

When silica fume is added to concrete initially it remains inert Once portland cement and water in the mix start reacting with each other (hydrating) primary chemical reactions produce two chemical compounds: Calcium Silicate Hydrate (CSH) which is the strength producing crystallization and Calcium Hydroxide (CH) a by-product also called free lime which is responsible for nothing much
