Abstract

Abstract
Aim: This paper presents the strength and performances of steel fibre reinforced concrete (SFRC) and hybrid fibre reinforced concrete (HFRC). The hybrid fibre is considered in the combination of hooked end steel fibres and polypropylenes fibres. Method: To study the durability properties, the fibre content dosage V f ranged from 0.5 to 2.0% of steel fibres, and 0.8SF0.3PP, 0.7SF0.3PP, 0.6SF0.4PP, 0.5SF0.5PP of hybrid fibres. 10 mixes including one control mix (without fibres) were prepared and tested in the laboratory. Durability study, acid resistances, sulphate resistances, salt water resistances, water absorption and rapid chloride penetrations test were also conducted in the 0 and 1.5% of steel fibres, 0.8SF, 0.2PP hybrid fibres. Non-destructive test (rebound hammer, ultrasonic pulse velocity test) before immersion and after immersion specimens was conducted. Results: Less numbers of cracks were observed in fibre reinforced high strength concrete specimens, which indicate an improved ductility with the addition of fibers in the matrix.
