Fly Ash, Grade: Class F

*Fly ash!* That's a super useful material. Fly ash is a byproduct of coal combustion in power plants. It's a pozzolanic material, meaning it reacts with calcium hydroxide to form cementitious compounds. Uses of Fly Ash: - *Construction*: Used as a partial replacement for cement in concrete, improving durability and strength. - *Soil Stabilization*: Used to improve soil properties for construction projects. - *Waste Management*: Used in the solidification and stabilization of hazardous waste. Types of Fly ash: - *Class F*: Produced from burning anthracite or bituminous coal, low calcium content. - *Class C*: Produced from burning lignite or sub-bituminous coal, high calcium content. Properties of Fly ash: - *Fineness*: Very fine particles, similar to cement. - *Pozzolanic Reactivity*: Reacts with calcium hydroxide to form cementitious compounds.
