Abstract
Roller compacted concrete (RCC) is a kind of dry and water-poor concrete, which has the advantage of less water consumption, fast construction speed using roller compaction machine compaction and low cost. RCC is often used in water conservancy projects. This paper outlines the effects of fly ash on the impact of compacted concrete in terms of compressive properties, flexural properties, dynamic modulus of elasticity, impermeability performance and crack resistance based on the working mechanism of fly ash in concrete. In a certain range, the performance of RCC is improved with the increase of fly ash content. Finally, this paper puts forward some suggestions for the further research of RCC.
