What Is Fly Ash Cement?
When coal and waste are burned in power plants, they create a non-combustible byproduct called coal ash. Two distinct types of ash particles make up coal ash: bottom ash, which collects on the bottom of coal furnaces, and fly ash, which is caught in the smokestacks. The vast majority of the non-combustible material is fly ash, which travels up in the flue gas and gets caught in the smokestacks and chimney. This residual needs to be cleaned out and disposed of on a regular basis. One way that this material can be reused is by combining it with other materials to create fly ash cement.
