Behavior of rc slabs under static loadusing high performance fiber reinforced concrete

High performance concrete being one of the most widely used concretewhich gives better performance and uniformity requirements that cannot always be achieved by using conventional concrete, since the conventional concrete has limited resistance to ductility and tensile cracking to overcome these difficulties discrete fibers are used in high performance concrete.Slab is a flexural member which transverse the superimposed loads from super structure to beams and columns. In static tests the ultimate load carrying capacity in structural design is one of the important factor.The present research is aimed at experimental investigation focused on the behavior of high performance fibre reinforced concrete slabs under static loading. A series of twelvetest slab specimens of size 600 mm x 600 mm with varying thickness of 60 mm, 50 mm and40 mm were casted and tested under fixed edge condition. M60 grade of concrete mix integrated with Polypropylene fiber of 900 gms/m3of concrete and 0.65% steel fiber by volume fraction. Load cells and LVDT’s are used to measure the load-deflection response. To study ductility index, toughness index and energy absorption capacity and cracking moment and consequently the load carrying capacity of test slab specimens from the load-deflection curve to access the enhancement in flexural strength using different fibre reinforced concrete matrices and same is to be optimize.
