Fly Ash in Self-Compacting Concrete

2001-6-1  Therefore, large volumes of fly ash, partially in substitution of cement and partially as filler, can be employed in producing self-compacting concrete. This paper compares the properties of fresh and hardened normal concrete and a self-compacting concrete with large volumes of fly ash. Significant advantages in the use of fly ash are demonstrated.
