Abstract
In this paper, the research on properties of existing main structural lightweight aggregate (LWA) in the China Pearl River Delta as well as the application of corresponding structural lightweight aggregate concrete (LWAC) were introduced. In the application of structural LWAC, this paper emphasizes the design, manufacturing, construction and economic analysis for application of precast LWAC facade of Hong Kong. As the research deepens, structural LWAC has been gradually accepted by construction industry in Pearl River Delta. Experiment research and engineering practice has proved that the mechanical properties and durability of structural LWAC can completely meet the engineering requirements.
