Experimental Study on Thermal Insulation Properties of Reinforced Concrete Composite Wall
The paper briefly introduces the form and construction method of a new reinforced concrete composite wall (RCCW) with inner insulating layer of polystyrene panel. The thermal insulation properties such as heat resistance, heat exchange resistance and heat transfer coefficient of the RCCW were measured by the protection chest method, six specimens in dimensions of 1450mm×1450mm×300mm were cast with the same thickness of prototype walls of building envelop, three kinds of linkages of the RCCW were considered, and two surfaces of the specimen were tested respectively as the heat bearing surface to simulated different heat resources. Based on the tests, the effects of linkages and heat resources on thermal insulation properties of the RCCW are analyzed, some improvements are proposed for reducing the heat-bridge effects as much as possible.
