Fly ash is a byproduct of burning coal in power plants. It is made up of a mixture of fine particles of inorganic materials, including silica, alumina, iron, and calcium. Because of its high levels of silica and alumina, fly ash can be used in a variety of construction materials, such as cement and concrete.
There are several methods for processing fly ash to make it usable for various applications. One common method is called “dry processing,” in which the ash is fed through a series of air classifiers, which separate the fine particles from the coarse ones. The fine particles can then be used in the manufacture of cement and concrete, while the coarse particles can be used as fill material or for other construction purposes.
Another method for processing fly ash is “wet processing,” in which the ash is mixed with water to form a slurry. The slurry is then passed through a series of filters, which remove impurities such as unburned carbon and other heavy minerals. The resulting material, which is called “processed fly ash,” is a fine powder that can be used in the same applications as dry-processed fly ash.
Another way to process fly ash is by using it as a substitute of cement in concrete. The concrete production method is similar as normal concrete but fly ash is added to the mixture of concrete as a replacement of some proportion of cement. This results in high strength and durability of the concrete and also reduces the environmental burden of cement production.
Finally, fly ash can also be used as a soil conditioner. The ash is spread over farmland and incorporated into the soil, where it can improve soil fertility and help to reduce erosion. Fly ash can also be used as a substitute for lime in agricultural applications.
Overall, processing fly ash involves separating the fine particles from the coarse ones, removing impurities, and then using the resulting material in a variety of construction and industrial applications. In addition,fly ash can also be used as a substitute of cement in concrete, soil conditioner and agricultural applications.
