| 摘 要： | 随着远海工程建设对建筑原材料的需求量与日俱增,若由内陆向海岛运送原料,其运输费用高、时效性差等问题显而易见。对于岛礁工程建设而言,可就地取材,将珊瑚碎屑作为骨料并加入海水拌制成珊瑚混凝土,同时采用纤维增强复合材料筋(FRP筋)作为结构增强筋,可有效解决海洋环境下钢筋锈蚀等耐久性问题。玄武岩纤维增强复合材料筋(BFRP筋)的力学性能优越,但我国对BFRP筋的研发起步较晚,尚未有充分的理论经验,故应对BFRP筋增强珊瑚混凝土耐久性展开系统研究,以确保岛礁工程建设的安全性。基于现有试验研究进展,在分析BFRP筋、珊瑚混凝土材料基本力学性能的基础上,对BFRP筋的耐久性、珊瑚混凝土的耐久性、BFRP筋-珊瑚混凝土界面粘结耐久性,以及BFRP筋增强珊瑚混凝土结构耐久性进行系统地概述与总结,并对BFRP筋增强珊瑚混凝土耐久性的后续研究进行展望。

| Abstract: | With the increasing demand of building raw materials for the coastal engineering, it is obvious that the transportation of raw materials from inland to islands incurs high transportation costs and poor timeliness. For the construction of island and reef engineering, coral concrete can be mode from local available materials by using coral debris as aggregate and adding seawater. Fiber reinforced polymer (FRP) bars are used as structural reinforcement bars, which can effectively solve durability problems such as corrosion of steel in marine environment. However, basalt-fiber reinforced polymer (BFRP) bars with excellent mechanical properties are limited by short research time and insufficient theoretical experience in China. Therefore, a systematic study on enhancing the durability of BFRP bars reinforced coral concrete should be carried out to ensure the safety of island and reef engineering construction. Thus, based on the existing research progress, the basic mechanical properties of BFRP bars and coral concrete are analyzed respectively, then the durability of BFRP bars, the durability of coral concrete, the bonding durability of the interface between BFRP bars and coral concrete, and the structure durability of coral concrete with BFRP reinforced are systematically discussed and summarized. Finally, prospect of future research on enhancing the durability of coral concrete with BFRP bars is proposed. |
