Silica fume

Silica fume is added to Portland cement concrete to improve its properties in particular its compressive strength bond strength and abrasion resistance These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste

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
