Generally concrete has low cracking resistance, low tensile strength and low ductility. To improve the tensile properties of concrete members a conventional reinforced bars are used. These provide the tensile strength of concrete members and do not increase the inherent tensile strength of concrete. It has been known that the addition of small, closely placed and uniformly dispersed fibers to concrete would act as crack arrester and improve it’s static and dynamic properties. In this paper, the mechanical properties like compression strength, split tensile strength, flexural strength, flexural toughness and stress – strain characteristics of SIFCON specimens and then compared with conventional FRC and conventional concrete are investigated. The M30 grade of concrete is used for both fiber reinforced concrete and conventional concrete. The experimental program consists of investigation on the mechanical properties of SIFCON specimens with 8% fiber content and then compared with conventional SFRC with 0.5%, 0.75% and 1% fiber content and then compared with conventional concrete. Steel fibers with two types straight and crimped having 30 mm and 18 mm length have been investigated. The result shows that the compressive strength of SFRC is found to increase with increase in fiber content. SIFCON has higher Split tensile strength and Flexural strength than SFRC and control concrete.
