Abstract:Ceramsite concrete sandwich floor slab is a type of composite floor slab, which is made of profiled sheet and ceramsite concrete. The empty stomach of sandwich slab is filled with polystyrene plate. This is a kind of new light-weight and energy saving plates. According to the mechanical experiment and theoretical analysis for three composite floor slabs, load-bearing mechanism and mechanical performance are analyzed. The calculation methods for rigidity, flexural capacity and shear resistance are put forward, which can give a reference for the engineering popularization and application of the sandwich slab.
