Abstract:For the 120-year design service life,we expound the principle of basic performance design of marine high-performance concrete for main structures of the Hong Kong-Zhuhai-Macao bridge.Based on the influencing factors of concrete long time durability of exposure test,we study systematically the influence of parameters of mix proportion on the properties of concrete.The ideas and methods of preparation of long service life marine high-performance concrete which satisfies the requirements of workability,strength,durability and volume stability for different structures of bridges and tunnels are presented.
Keywords:long service life  marine high-performance concrete  parameters of mix proportion  exposure test  durability
