| Abstract: | The estuary floodgate project lied to the splashed area by the spray in the yellow sea.Concrete structures are exposed to the corrosion of seawater.The high performance concrete and other synthetical technologies were applied to enhance concrete durability in construction of the project,which included the design of covering layer of concrete,the mix proportion design and optimizing of HPC groups,exterior treatment of concrete,the organization and control of structure,etc.The durability indexes of the made concrete such as impermeability,freeze-thaw cycling resistance,strength,corrosion of sulfate and chloride etc all satisfied equirements.Better technical and economic effects were acquired. |
