  • Abstract:
  • - In the present scenario, use of concrete as a structural material is limited to certain extent by deficiencies like brittleness, poor tensile strength, and poor resistance to impact strength, low ductility and low durability. In this study, experimental investigation on the compressive and tensile strengths behavior of P.C.C cubes and cylinders by using Steel fibers in concrete mix and Glass Fiber of thickness 12MM are used. Crimped steel fibers and glass fiber are used and mixed in ratios of 0%, 0.5%, 1.0%, and 1.5% of cement quantity. The grade of cement is 53 and concrete is M40. 2.75mm passed fine aggregate and 20mm size of coarse aggregates is used. Super plasticizer Conplast SP430 is added. Destructive tests are performed to find out the compressive strength and split tensile strength of adopted grade of concrete. These tests are carried out to the specimen’s failure in order to understand a specimen’s performance or behavior under different loads. The test results show that the strength of the concrete increases with increase in fiber percentage up to certain percentage therefore it is decreasing. Fly ash blended concrete shows considerable resistance to sulphate attack. The strength of the concrete is optimum at 1% of glass fiber and 0.5% of steel fiber. Overall, the glass fiber shows great increment of strength when compared to steel fibers.
