The Behaviours Of Steel Fiber As Main Reinfocement In High Performance Slurry Infiltrated Fiber Reinforced Concrete

Normally, the concrete structure is fabricated by combining steel bars as main reinforcement to the concrete mix. Nowadays, new material can be used to replace the steel bars by using steel fiber. In this method, the steel fiber is randomly distributed in the mould before the concrete slurry takes place. In this study, high grade concrete slurry grade 80 was used. In order to determine the behavior of the steel fiber as reinforcement in concrete, three different percentage of steel fiber used, 3%, 4%, 5% and also the control sample without fiber. Sizes of prism used in this study are 100 x 100 x 500 mm. The behavior of steel fiber was investigated by using two-point load test until failure. The load-deflection data was recorded from the two-point load test. Based on the result, it was concluded that the optimum steel fiber content in this report was 5 % by volume friction which provided the highest flexural strength and deflection.
