【摘要】：海砂的资源化开采和应用不仅能解决沿海地区建筑用砂紧缺的难题,而且对环境、资源保护有重大意义。本文回顾了已有的钢筋海砂混凝土结构应用,钢筋锈蚀带来的建筑质量问题十分严峻,虽然可以用严格的海砂淡化方法避免,但是需要消耗大量的淡水资源,使用受限且综合效益低。而FRP耐氯盐腐蚀,性能优异,海砂混凝土与其组合应用可从根本上避免锈蚀问题,目前已有了一系列应用形式,而且未来发展前景广阔。本文介绍了已有的相关研究,并针对我国海洋开发的重大需求提出了一种面向海洋的新型FRP海砂混凝土组合结构,为海砂混凝土与FRP在工程建设中的应用提供了新的思路。
[Abstract]:The exploitation and application of sea sand can not only solve the shortage problem of building sand in coastal area, but also have great significance to environment and resource protection. This paper reviews the existing application of reinforced sea sand concrete structure. The problem of building quality caused by steel bar corrosion is very severe, although it can be avoided by strict desalination method, but it needs to consume a lot of fresh water resources, its use is limited and its comprehensive benefit is low. FRP is resistant to chlorine salt corrosion. Excellent performance, the combination of sea sand concrete and its application can fundamentally avoid the problem of corrosion, there have been a series of applications, and the prospects for future development are broad. This paper introduces the existing related research. In order to meet the great demand of marine development in China, a new type of marine FRP sea sand concrete composite structure is proposed, which provides a new way of thinking for the application of sea sand concrete and FRP in engineering construction.
