摘要
利用海水和海砂替代淡水河砂,不仅能够有效缓解自然资源匮乏等问题,还对海洋工程的建设具有深远的意义。本文综合分析了国内外现有的研究成果,深入探讨了海水海砂的材料特性以及海水海砂混凝土的力学性能,最后针对海砂对混凝土结构耐久性的危害提出若干防治措施,以期减少海砂对钢筋混凝土的危害。
Utilizing seawater and sea sand to replace fresh water and river sand can not only effec‐tively alleviate the problem of natural resource scarcity,but also has profound significance for the construction of marine engineering.This article comprehensively analyzes the existing research results at home and abroad,deeply discusses the material properties of seawater and sea sand as well as the mechanical properties of seawater sea-sand concrete.Finally,several prevention and control measures are proposed for the harm of sea sand to the durability of concrete structures,aiming to reduce the harm of sea sand to reinforced concrete.
