EXPERIMENTAL INVESTIGATION ON STEEL FIBRE REINFORCED CONCRETE SLAB WITH PARTIAL REPLACEMENT OF COARSE AGGREGATE

Abstract :

 Concrete is a composite material consisting of mortar and coarse aggregate. An existing problem of RC slab is formation of cracks. In this study steel fies are added in concrete to control the crack formation and development in RC slabs. 1% of steel fie is added in concrete, which is the efficient percentage of addition in reinforced concrete. In addition to that to overcome the scarcity of conventional coarse aggregate now–a–days usage of Re–Cycled Aggregate is highly recommended. A conventional method is proposed by using Re–Cycled Aggregate (RCA) as partial replacement of coarse aggregate to its weight with addition of 1% of steel fie to the volume of concrete in specimen. One–way slab of size 1350 x 500 x 100 mm is casted and tested, which is designed according to Indian standard codes. The flexural properties of the slabs are compared between control specimen and 0%, 20% and 40% partially replaced re–cycled aggregate specimens.
