粉煤灰对混凝土性能的影响

Fly ash affecting ability of concrete

粉煤灰是高性能混凝土的主要掺合料之一,掺加粉煤灰直接影响到混凝土的各方面性能.本文综述了粉煤灰的掺量对混凝土的工作性能、力学性能以及耐久性的影响.介绍了国内外此方面的研究进展,认为混凝土中掺加适量的粉煤灰能够很大程度上使混凝土性能优化.

Fly Ash （FA） was one of major mineral admixtures, and affected the abilities of concrete. The fly ash affecting the workability, mechanical properties and durability of concrete was introduced in the paper. It was showed that the proper amount of fly ash could improve the workability, mechanical properties and durability of concrete.
