The project aims at an experimental investigation of composite beam to predict the structural performance. The composite beam consists of two steel plates placed at top and bottom to be filled with concrete. The steel plates are interconnected using headed stud and J hook shear connectors with 100mm and 120mm spacing to improve composite beam action between the plates and concrete. The concrete core consists of superabsorbent polymer as internal curing represents standard weight concrete. The strength of the self-curing concrete grade of M25.Mix proportion in accordance with IS10262:2000. Super absorbent polymer can be used in 0.3% and 0.4% weight of cement. In SCS, normal curing is not applicable because of corrosion of steel plate and shear connectors which occurs due to the interaction of water. Since it is a prime factor, to develop a self-curing concrete using super absorbent polymer as self-curing agents. The strength of concrete containing of self-curing agent was tested and compare with conventionally cured concrete. A mild steel plate of 4mm thickness in both the faces of the composite beam. The composite beam size to be tested in this project is 450x150x150mm of 8nos of varying spacing of shear connectors. The composite beam is loaded and tested under the two-point bending systems.
