Because fly ash is initially a waste byproduct of coal-burning operations, FA-concrete is a cost-effective alternative to concrete made with only Portland cement as the binder. That alone is enough to pique the interest of concrete producers and contractors. Its versatility as a construction material makes it even more attractive. Because it has greater flowability, contractors find it reduces time at the job site. In addition, FA-concrete has shown improved strength and durability, which means that buildings, bridges, roads, and sewers have the potential for longer life.
