Abstract

This study describe the mechanical properties of fresh and hardened state hybrid steel fibre reinforced concrete with different aspect ratio and volume fraction. Twenty one mixes included one control mix (without fibre) were prepared and tested in the laboratory. Workability tests were conducted to investigate the properties of the fresh concrete mixes. Meanwhile, the properties of the hardened concrete were investigated using compressive tests, split tensile tests and flexural strength tests. The results indicate that the hybrid steel fibre reinforced concrete (at volume fraction of 1.5%, consisting of 70% long fibre and 30% short fibre) gave the highest value of flexural strength and split tensile strength. On the other hand, the concrete mix containing 30% long fibres and 70% short fibres at 1.5% volume fraction gave the highest compressive strength. It was also observed that by increasing the percentage of fibre volume in the mix, the workability of the concrete mix will reduced.
