AN INVESTIGATION ON LIGHT WEIGHT CONCRETE TO CONSTRUCT PREFABRICATED COMPOSITE PANEL

Steel-Concrete Composite construction is widely accepted technique in the construction industry. Sandwich Composite panel is heterogeneous in nature. The reduction in weight of concrete helps easy removal, transport and erection of precast products. So necessity of light weight precast panels arises there. Here we have discussed about three different varieties of panels, which can be used further for the construction purpose. Here we prepare sandwich composite panel consist of three layers of two different materials (concrete and steel). Panels are created with corrugated steel sheet or decking sheet sandwiched between foamed concrete, fiber reinforced foamed concrete and polystyrene concrete. Behaviors of sandwich panels were studied in detail. Advantages and disadvantages of light weight panel construction are examined here. It was found that advantages are more compared to the disadvantages. Environmental pollution due to excess usage of thermocol is solved here by introducing this waste material into the concretes thus makes it economical and more suitable for the specified purposes. Determination of Cube Compressive strength, split tensile strength for cylinder specimen is done here for foamed concrete and thermocol mixed concrete which is used to make the panels.
