Performance Evaluation of Fiber Reinforced Concrete For Structural Applications

To achieve composite material uniformity, polypropylene fiber was added to the dry-mix prior to the addition of steel fiber. The polypropylene fiber prevented the heavier steel fiber from settling out of solution. Casting for each experimental group was performed using the same standard moulds and mechanical vibration of the cast was used to encourage maximum compaction. Following casting, the specimens were water-cured for 7 and 28 days prior to mechanical testing.
