Experimental Study on the Mechanical Property of Concrete-Foam Glass Sandwich Block

Abstract

Foam glass is a kind of inorganic heat-insulating material. It possesses excellent properties such as fire proof, water proof, heat keeping and insulation, sound absorption. But foam glass is hard and brittle; it is easy to be broken in the process of transportation and construction. Furthermore, the construction technology is complex and uneconomical whether in the external or internal thermal insulation system in construction. In this paper, foam glass plate was inserted in the concrete test block and was poured together into the Sandwich block. The compressive strength and the tensile strength normal to the interface between the foam glass and concrete blocks were studied through experiments. It will provide effective technical supporting for further study on the manufacturing of integrally poured concrete-foam glass Sandwich building blocks.
