环境因素对混凝土氯离子侵蚀对流区的影响研究

摘要

以人工气候环境和感潮河口自然环境下的混凝土试件为研究对象，通过试验检测，研究了不同环境条件下水灰比和腐蚀时间对混凝土中对流区深度的影响。试验结果表明，人工气候环境和感潮河口自然环境下，水灰比对对流区深度的影响并不明显，延长腐蚀时间会适当增加对流区的深度。%The paper deal with the influence of water- cement ratio, corrosion time on the concrete convention depth of corroded concrete specimens under artificial and estuarine natural environment by means of experimental testing and analysis in the paper. Results show that in both artificial environment and estuarine natural environment, the water- cement ratio has no influence on the concrete convention depth, but concrete convention depth is deeper as corrosion time increased.
