A Comparative Study on Various Mix Designs of Concrete by Using Steel and Glass Fiber

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. 7 and 28days compressive strength and 28 days spilt tensile strength and flexural strength; tests have been performed in the hardened state. In this project the behaviour of cube, cylinder & beam structures strengthen by using FRC is experimentally tested. The fiber used are steel and glass fibers in sundry volume fraction the main reason for integrating steel fiber to concrete matrix is to ameliorate the post cracking replication of the concrete i.e. to ameliorate its energy absorption capacity and ostensible ductility and to provide a crack resistance and crack control and addition of glass fiber form bridging the micro-cracks are suggested as the reason for the enhancement in flexural strength.
