Abstract: 
This research investigate fibres geometrical factor to the performance of steel fibre reinforced concrete. For this purpose, three types of hooked-end deformed steel fibres with 33 mm, 50 mm and 60 mm length were chosen as a compliment with C40 grade concrete. These types of steel fibres were chosen based on their frequent use in various research investigations as well as the industrialisation program. The steel fibres were identified as SF60, SF50 and SF33, and for each length, the volume fraction were gradually increased from 0% and up to 2% with 0.25% increment. This give a total of 24 batches for SFRC with different volume fraction and aspect ratio, and one batch of plain concrete as a control. The research methodology focused on assessed the mechanical performances of SFRC based on compressive, splitting tensile and flexural behaviour compared with plain concrete. Correlations between factor of fibres geometry as well as concrete strength were proposed as a reliable benchmark to assist SFRC investigators in the future works. Reliabilities of the proposed correlations were made based on the comparison with other previous models. The proposed correlation equations give pattern approaching the experimental data and strong coefficient of determination.
