What are the functions of fly ash?

The decrease in temperature rise of concrete: Adding fly ash can reduce the amount of cement used, and the hydration heat of fly ash is very low, thereby reducing the hydration heat. Therefore, the temperature rise of concrete during construction is reduced,
The decrease in temperature rise of concrete: Adding fly ash can reduce the amount of cement used, and the hydration heat of fly ash is very low, thereby reducing the hydration heat. Therefore, the temperature rise of concrete during construction is reduced, which can significantly reduce temperature cracks, which is very beneficial for large volume concrete engineering.
The workability of concrete mixtures has been improved: Adding an appropriate amount of fly ash can improve the fluidity, cohesiveness, and water retention of concrete mixtures, making them easy to pump and pour into shape, and reducing the loss of slump.
Improved durability of concrete: Secondary hydration improves the compactness of concrete, improves the interface structure of concrete, reduces the amount of calcium hydroxide that is prone to corrosion during secondary reactions, and enhances the impermeability, sulfate corrosion resistance, and magnesium salt corrosion resistance of concrete; Meanwhile, due to the large specific surface area and strong adsorption capacity of fly ash, fly ash particles can adsorb alkali in cement and react with alkali to consume alkali. Reducing the amount of free alkali can inhibit or reduce the alkali aggregate reaction.
