Fly ash is a widely used material that can be used in various applications. The following are some of the main uses of fly ash:
building materials
As a cement admixture, fly ash can partially replace cement in cement, which can reduce the cost of concrete and improve its durability. Fly ash can also make concrete easier to flow and pour.
As a concrete additive, fly ash can improve the workability, durability, and impermeability of concrete. It can also reduce the heat and shrinkage rate of concrete.
Manufacturing bricks and concrete blocks: Fly ash can partially replace clay and sand in bricks and concrete blocks. This can reduce the cost of bricks and concrete blocks and make them more lightweight. Fly ash bricks and concrete blocks also have good thermal insulation and fire resistance properties.
As a filler for asphalt pavement: Fly ash can enhance the strength and durability of asphalt pavement. It can also reduce the cracking and rutting of asphalt pavement.
Other uses
Agriculture: Fly ash can be used as a soil amendment or fertilizer. It can improve the fertility and air permeability of the soil.
Environmental protection: Fly ash can be used as a wastewater treatment agent or adsorbent. It can remove heavy metals and other pollutants from water.
Manufacturing other products: Fly ash can be used as a filler or additive for rubber, plastics, ceramics, and other products.
The utilization of fly ash can help reduce waste in the construction and construction industry, and protect the environment. With the advancement of technology, the application fields of fly ash will further expand.
