Study on raw materials and structural performance of coral concrete composite structure

Abstract

Coral Reef Sand, as the concrete aggregate for the construction of marine island engineering, has the characteristics of light weight, environmental protection, energy saving and easy financing, and it has been used in the plain concrete engineering such as revetment and road. Considering the rich resources, combined with structural assembly and composite structure technology, a new type of composite structure with Coral Concrete-Filled Steel Tube(beam) with Wrapped FRP is proposed, it can be used in marine engineering. Through experimental research and analysis, the performance of raw materials and composite structure is obtained, which can provide the theoretical basis and design reference for application.
