Experimental process: Lightweight concrete composite slab . . and its foundations, in fact the self weight of the concrete is treated as a variable load composite slabs consist of profiled steel decking with an in-situ reinforced concrete.
The reduced self weight of composite elements has a knock-on effect by reducing the forces in those elements . The floor slab may be in the form of a precast concrete slab or a composite slab with metal decking (either shallow or deep

1 Sep 2017 In order to study the shear-bond action in embossed composite deck slabs, Marimuthu et al. Luu et al. reported that the use of lightweight concrete allowed a reduction of the dead load of the composite slab by 40% compared to normal concrete . The profiled steel sheet used for the specimens was of TYPE A. The corresponding self-weight and maximum load were calculated for a
10 Jul 2009 lightweight aggregate concrete, the composite deck slabs offer henceforth new assets such as higher unpropped span during construction, supplementary reduction of self weight of the floor (up to 40% compared to the normal
