Fly Ash Cement Australia

Fly ash is a byproduct of coal combustion in power stations. Aside from offering environmental advantages by reusing industry waste, adding fly ash also improves the overall performance and quality of concrete. Fly ash affects the plastic properties of concrete by improving workability, reducing water demand, controlling bleeding, and lowering the heat of hydration.
