The influence of materials and production process on RPC compressive strength

Abstract

In addition to the water binder ratio, the production process, fiber, silica fume and admixture have a significant impact on the compressive strength of RPC. Several factors such as materials and production process affecting RPC compressive strength were studied by experiments. It exhibits that the reinforcement influence of steel fiber on RPC is affected by the strength of composite matrix. The higher the strength of composite matrix is, the better the effect of fiber reinforcement is. The compressive strength of RPC can be greatly improved by vacuum vibration forming. The water demand and activity of silica fume have significant influence on the compressive strength of RPC.
