FLEXURAL BEHAVIOUR OF HIGH STRENGTH REACTIVE POWDER CONCRETE

This study shows the experimental study on high strength reactive powder concrete using available materials specifically silica fume, silica powder and ordinary Portland cement. The curing cycles are employed only under normal water curing. The maximum cube compressive strength obtained in 28 day is 87 N/mm2 using steel fibres. In Further, split tensile test and flexure testing is also conducted and the results are tabulated. The reactive powder concrete is then used in flexure beam, the ultimate load obtained was 90 kN followed by maximum deflection is 9.3mm and stiffness is 8.7 kN/mm which is effective for the structural purposes.
