Performance of expanded polystyrene light weight self compacting concrete in composite slab

Performance of expanded polystyrene light weight self compacting concrete in composite slab

Composite constructions have gained importance due to faster and economical construction. Composite sections are generally made with cold formed corrugated profile sheet, which also act as a permanent formwork. To promote the use of composite sections in construction industry, it is necessitate to target to minimize the self-weight. It also facilitates to save the construction cost. In composite slabs, shear connectors are provided for composite action. It would be difficult to pour the conventional concrete; hence self compacting concrete would be ideally suited for such places. To reach the above objective, an effort has been made to investigate the expanded polystyrene light weight self compacting concrete in composite slab. To achieve the light weight concrete, expanded polystyrene beads were added in different proportions to the coarse aggregate. The composite slab was performed for four-point bending test under flexure and push out test. The test result concluded that the light weight expanded polystyrene self compacting concrete composite slab exhibit a higher performance with reduction in the thickness of the slab. The minimum spacing of shear connector was well performed. It could able to control the shear crack and de-bonding effect between the profiled steel sheet and concrete.
