This study also found strong correlations between concrete splitting tensile strength (fct), compressive cube strength (fcu) and flexural strength (ft) where R2 were between 0.82 and 1.00 for steel fibres with an aspect ratio of l/d = 80 and volumetric percentage ranging from 0.5% to 1.25%. The quantitative values for this study can be improved by conducting a study with various types of SFs available in the market i.e. aspect ratios, SFs shapes and different concrete classes i.e. normal concrete or even high strength concrete
