滨海地区变电站地下混凝土结构防腐抗渗研究

Research on anti-seepage and anti-corrosion of underground concrete structures for substations in coastal area

天津滨海地区的地下水含有较多的腐蚀性物质.本研究针对水质化验分析结果,采用不同比例掺量外加剂、不同比例掺量的地下腐蚀离子模拟,进行混凝土抗渗漏试验研究.经过不同配比、不同外加剂、不同腐蚀介质掺量的混凝土现场同条件实验,取得抗渗结论,为滨海地区地下混凝土施工提供了重要的参考依据.

The groundwater of Tianjin coastal area contains a lot of corrosive substances.Based on the results of the test analysis of water quality,anti-seepage test research is done on cement concrete by adopting admixture of different mixing ratios and underground corrosive ion simulation of different mixing ratios.under the in-site same conditions;the experiment is done on the cement concrete of different proportioning and different admixtures and different corrosive media mixture;and then the anti-seepage conclus...
