Aiming at the problem that concrete structures are susceptible to erosion in seawater environment,we introduce the application of high-performance concrete in the wharf of Yantian Port east operation area,and carry out a large number of test data analysis.The results show that the concrete produced can meet the requirements of high durability,high workability and high strength by adopting lower water-binder ratio and high-quality raw materials,mixing a sufficient number of mineral admixtures and high-efficiency admixtures,and adopting the necessary quality control measures,which can provide reference for hydraulic structural concrete.
