The influence factors of the workability of roller compacted concrete

摘要

The workability is an important property for roller compacted concrete (RCC). Because of different construction process, the requirement of its workability is differ from the normal concrete. So, the factors which will affect the workability of RCC should be considered in mixture gradation design. The effects of cement content, water cement ratio, maximum size of aggregate and mixing time on the workability of RCC were tested.
