Fly Ash - Properties, Types, Mechanism and Uses

If we have Portland cement, and the fly ash is the pozzolana, it can be represented by silica because non-crystalline silica glass is the principal constituent of fly ash. The silica combines with the calcium hydroxide released on hydration of Portland cement. Calcium hydroxide in hydrated Portland cement does not do anything for strength, so therefore we use it up with reactive silica.

PROJECT PROFILE ON FLY ASH BRICKS - DCMSME
