Abstract

This work investigated the effects of fibre type, dosage and maximum aggregate size on the flexural performance of steel fibre reinforced concrete (SFRC). Hooked-end steel fibres with 50 mm and 60 mm length, aspect ratio of 45, 65 and 80, and dosages of 0 kg/m³, 25 kg/m³, 40 kg/m³, 50 kg/m³ and 60 kg/m³ were used with maximum sizes of coarse aggregate of 10mm and 20mm. The same mix proportion of concrete was used in the investigation. The experimental results show that the strength performance of SFRC improved drastically when compared to plain concrete without fibres. Remarkable improvements were observed at larger dosages of steel fibres, particularly at 50 kg/m³ dosage and with fibres with aspect ratio 80 noted to give the best results.
