A COMPARATIVE AND EXPERIMENTAL STUDY OF VARIOUS MIX DESIGN CONCRETE USING STEEL AND GLASS FIBRE

Civil Engineering

Concrete is the most common materials used in the construction industies. In the past few years, many and modification has been done to produce concrete which has the desired characteristics. There is always a search for concrete with higher strength and durability. Plain concrete has good compressive strength but has low tensile strength, low ductility and low fire resistance .This research paper aim to study characteristics and comparison of the mechanical properties of steel and glass fiber reinforce concrete with conventional concrete. In order to achieve and verify that 1%,2%,3% fiber percentage by the volume of cement are used in this study with three different concrete mixes M20, M25, and M30. 28days compressive strength, spilt tensile strength, flexural strength, tests have been performed in the hardened state. In this project the behavior of cube, cylinder & beam structures strengthen by using FRC is experimentally tested. The fiber used are steel and glass fibers in various volume fraction the main reason for adding steel fiber to concrete matrix is to improve the post cracking response of the concrete i.e. to improve its energy absorption capacity and apparent ductility and to provide a crack resistance and crack control and addition of glass fiber for bridging the micro-cracks are suggested as the reason for the enhancement in flexural fiber.
