STRENGTH AND DUCTILITY OF POLYMER MODIFIED STEEL FIBER REINFORCED FLEXURAL MEMBER

This study deals with the mechanical properties of conventional concrete, polymer modified concrete (SBR), and incorporation of steel fibres are studied with constant percentage of polymer (SBR) and various percentage of Steel fibre (0.5%, 1.0% and 1.5%). Based on the mechanical properties the mix proportion is optimized. This paper contains with flexural behaviour study of polymer modified concrete with and without steel fibres concrete beams. In this investigation the conventional concrete, constant percentage of polymer modified concrete and various percentages of Steel fibre (0.5%, 1.0% and 1.5%) specimens were cast for the slump range of 50 to 75 mm, and its mechanical behaviour was obtained from compression, E for concrete and Flexure test. The mix was finalized from Constant percentage of polymer and various percentage of Steel fibre. For the Finalized mix proportion from the mechanical properties, Two beams were cast for every Finalized mix (control + Polymer (10%), (control + Polymer (10%) + Steel Fibre) and the flexural behaviour were studied using static two point load and the results were compared with theoretical value
