Abstract

Investigation to overcome the brittle response and limiting post-yield energy absorption of concrete let development of the fiber reinforced concrete using discrete fiber within the concrete mass. A wide variety of fiber have been proposed by the researchers such as steel, glass, polypropylene, carbon polyester, acrylic and aramid etc. fiber reinforced concrete (FRC) is an emerging field in the area of concrete technology. Here an attempt has been made to investigate particularly “Steel Fiber” as fiber reinforcement in concrete. A concrete mix design has been designed to achieve the minimum grade of M30 as required by IS 456-2000. The investigation contains three phases. In first phase, to identify the effect on workability due to addition of fibers. Second phase contain test on standard specimen such as compressive strength, split tensile strength and flexural strength by varying the fiber percentage from 0.5% increasing by 0.5% up to 3.0%. Third phase compare the strength of various fiber specimen with plain concrete strength. Totally 42cubes, 42 cylinders and 42 prism were casted and tested. Based on the experimental workability and mechanical strength studied, volume fraction from 0.5% to 3.0% and two aspect ratio of 45 to 60 have taken for the investigation.
