FRP筋海水海砂混凝土研究现状综述

Research Summary on FRP Reinforced Seawater Sea-sand Concrete

海砂混凝土和纤维增强复合材料筋(FRP筋)的组合应用是避免传统钢筋混凝土结构锈蚀破坏的有效途径。该文介绍了FRP筋、海砂混凝土、海水海砂混凝土和FRP筋海水海砂混凝土的研究现状和应用情况,指出FRP筋海水海砂混凝土尚需研究的问题。FRP筋海水海砂混凝土的研究和应用,能为我国沿海建筑用砂紧缺和岛礁建筑等海洋开发提供新的建设思路。

The combined application of sea-sand concrete and fi ber reinforced polymer(FRP) bar is an ef fective way to avoid the corrosion damage of traditional reinforced concrete structures. This paper reviews the research status and application of FRP bars,sea-sand concrete, seawater sea-sand concrete and FRP reinforced seawater sea-sand concrete, and points out the problems that need to be studied on FRP reinforced seawater sea-sand concrete. The research and application of FRP reinforced sea-sand concrete can provide new construction ideas for coastal building sand shortage and ocean development such as island building.
