FRP与海砂混凝土组合应用的发展与创新

摘要/Abstract

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 use of sea sand in engineering construction is an effective solution to solve the problem of shortage of building sand in the coastal area not only, and is also reduces environmental impact. Upon review of the existing reinforced sea sand concrete applications, it is clear that there have been many substandard outcomes, primarily due to steel corrosion. Although these problems can be largely avoided by thoroughly washing sea sands with fresh water, the process is extremely water intensive, meaning that its overall usefulness is limited. However, fiber reinforced polymer (FRP) materials have both excellent mechanical performance and resistance to chloride-induced corrosion. Using FRP reinforcement and sea sand concrete in concert can avoid corrosion problems entirely. There are already many potential applications for this type of composite structure, and the prospects of further future development are equally good. An innovative FRP-concrete hybrid structural system for use in seaborne engineering is proposed herein. Specifically, this structure aims to fulfill an increasing demand for seaborne and coastal development. Meanwhile, it is also hoped to promote the application of sea sand concrete and FRP in engineering structures.

Key words: sea sand concrete, corrosion resistance, offshore construction
