Abstract: The use of seawater sea-sand to replace freshwater and river sand in concrete preparation not only relieves the consumption of resources in the civil engineering industry, but also saves a lot of transportation costs and time costs for the construction of coastal cities and distant islands in situ. Therefore, the research on the resource utilization of seawater sea-sand has become particularly critical. This paper aimed at seawater sea-sand concrete (SSC). The researches on the characteristics of seawater sea-sand at home and abroad were compared. The mechanical properties of SSC, the durability of SSC under dry-wet cycles and freeze-thaw cycles, and the development of the bonding properties between SSC and fiber reinforced polymer (FRP) bars were analyzed. Finally, the current research results of seawater sea-sand concrete were summarized, and suggestions for future research were made.

Key words: seawater sea-sand concrete, mechanical property, dry-wet cycle, freeze-thaw cycle, FRP bar, erosion mechanism
