动态水化学侵蚀耦合作用下混凝土的力学特性

Mechanical Property of Concrete under Coupling Effect of Dynamic Water and Chemical Erosion

模拟了动态水环境下硫酸盐和碳酸盐对混凝土的侵蚀作用,进行了混凝土力学性质试验,研究了动态水和侵蚀环境耦合作用下混凝土的腐蚀特性。试验结果表明,动态水和侵蚀溶液的耦合作用对混凝土的侵蚀更加明显。此外,对混凝土的腐蚀机理进行了分析。其研究对处于侵蚀性地下水渗流以及流动水冲刷等环境下混凝土的耐久性设计和应用具有参考价值。

The erosion effect of sulfate and carbonate on concrete under dynamic water environment is simulated in this paper.The mechanical property of concrete is tested to study its corrosion characteristics under coupling effect of dynamic water and chemical erosion.The result shows that coupling of dynamic water and erosion solution has more significant erosion effect on concrete.In addition,corrosion mechanism of concrete is also analyzed.The research has reference for concrete durability design and application in the environment of erosive ground water seepage and running water erosion.
