Vibrating Compaction and Pressure Curing of Steel Fiber Reinforced Concrete

Abstract

The vibrating compaction, pressure compaction and pressure curing of fiber reinforced concrete were investigated for the purpose of utilizing steel fiber to concrete products. In the vibrating compaction, the adoption of high frequency or high vibrating accelerator was profitable to improve the quality of fibrous concrete. The pressure compaction and pressure curing of steel fiber reinforced concrete were very effective to obtain high flexural strength and to improve the impact resistance. As the effect of reinforcement is increased by the pressure method, it is possible to reduce the fiber content for a given required strength.
