Fly AshSource: Boral Material Technologies Inc.
Class F fly ash increases the ability of concrete to resist attack from sulfates in soil or groundwater and potentially disruptive alkali-aggregate reaction. It is produced from the combustion of pulverized bituminous or Texas lignite coal.
When designing concrete mixtures, fly ash is normally considered part of the cementitious content. As such, current technology favors optimizing its use as a discrete raw material. This fly ash may be used as a separate concrete addition, a partial replacement for portland cement, and a partial replacement for portland cement and as an addition.
