| 摘 要： | 利用海水海砂替代淡水河砂制备混凝土不但能缓解土木工程行业对资源的消耗,而且对于沿海城市及远海岛礁建设而言,就地取材节约了大量的运输成本和时间成本,因此,对于海水海砂资源化利用的研究变得尤为重要。以海水海砂混凝土为研究对象,通过对比国内外学者对海水海砂特性的研究,综合分析了海水海砂混凝土力学性能以及干湿循环和冻融循环下耐久性能以及海水海砂混凝土与纤维增强聚合物(FRP)筋组合结构粘结性能的发展规律。最后对目前海水海砂混凝土研究成果进行了总结,并对未来的研究内容提出了建议。

| 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. |
