  • Abstract:
  • This work investigates the strength properties of fiber reinforced concrete by a comparative study between Natural (sisal) and Artificial (steel) fiber reinforced cement concrete by partial replacement of fine aggregate with M-sand (Robo sand) at constant percentage of 50%. In our project, we would like to take the naturally available fiber named sisal fiber and artificially available fiber named steel fibers is taken as a substitute material to the reinforcement. The fibers of sisal and steel are used with same ratios comparatively by varying 0.25%, 0.5%, 0.75%, & 1% respectively to the weight of cement. Natural fibers are generally needed chemical treatment so the sisal fibers are treated with Noah solution and both the fibers are taken in to 35mm length. The following tests are conducted by such as compressive strength test, split tensile strength test, flexural strength test using M30 grade of concrete. As per my calculation M30 target strength for the compressive strength, split tensile strength and flexural strength of 7days, 28days concrete is 31.72 & 43.44, 5.32 & 6.28, 5.96 & 7.09 at 1% sisal fiber and 33.47 & 49.96, 5.36 & 6.38, 6.12 & 7.28 at 1% steel fibers by 50% replacement of fine aggregate with m-sand. In this work, replacement of fine aggregate with manufactured sand has resulted in a considerable increasing the mechanical properties of concrete. M-sand at 50% and both fibers in the concrete were identified as optimum 1% in sisal fibers and 1% in steel fibers of M30 grade of concrete to a conventional concrete. As per test results sisal fiber reinforced concrete achieved nearly same mechanical properties compare to the steel fiber reinforced concrete and steel fiber reinforced concrete is achieved better mechanical properties compare to the sisal fiber reinforced concrete.
