Evaluation of Mechanical Properties of Steel Fibre Reinforced Concrete with OPC43 and 53 Grades

The various previous research studies have proved that plain concrete possesses low tensile strength, low resistance to cracking and limited ductility. The addition of fibers enhanced various characteristics of concrete, it has also been proved that the use of steel fibres improved the strength of concrete. Steel fibre is considered to be the most popular type of fibre used as concrete reinforcement. The basic purpose of using steel fibre is to prevent or control plastic and drying shrinkage. Steel fibres also increase flexural strength, ductility, durability and reduce fatigue. The present study focuses on the mechanical properties of steel fibre reinforced concrete. (SFRC) prepared with two grades of OPC 43 and 53. As per IS 10262-2009 M40 grade of concrete with super plasticizer at water cement ratio 0.40 is considered for the study. The steel fibre with varying percentage of composition i.e. 1%, 2 %, 3%, 4%, 5% and 6% is added by weight of cement. The strengths and durability of SFRC are studied and compared with the controlled concrete.
