Abstract: A sandwich panel is a lightweight structure, economical and having low thermal conductivity. It is made up of three layers in which the middle layer is low-density core bounded with a thin concrete layer at top and bottom. The main objective of this study is to find out the flexural behaviour of Sandwich slabs with concealed beams arranged in two different ways. The experimental investigation consists of four different slabs one in conventional reinforced cement concrete slab and the second model is sandwich slab and the third model is the sandwich slab with a concealed beam provided in one direction. The fourth model is a concealed beam provided in both perpendicular directions. To examine the flexural behaviour of sandwich panels, a loading frame of capacity 200 tons have been used. The Load versus deflection and crack pattern were observed and recorded by Linear variable differentiable transducers (LVDT). The results are obtained by varying parameters like direction and number of a concealed beam. There is a significant change in flexural behaviour of the sandwich slab with a concealed beam in both perpendicular directions compared to other specimens.
