Introduction to PFA Cement
PFA (Pulverized Fuel Ash) cement, also known as fly ash cement, is a type of blended cement that incorporates pulverized fuel ash, a by - product of coal - fired power stations. When coal is burned in power plants, the fine ash particles are carried away by the flue gases and are then collected. This collected ash, when processed, can be used as a partial replacement for Portland cement in concrete production.
PFA cement offers several advantages. It improves the workability of fresh concrete, making it easier to place, compact, and finish. It also enhances the long - term durability of concrete, reducing the risk of cracking and increasing resistance to chemical attacks, such as sulfate and chloride ingress. Additionally, using PFA cement is an environmentally friendly option as it reduces the demand for Portland cement production, which is energy - intensive and a significant source of carbon dioxide emissions.
