混凝土腐蚀的正交试验研究

The Study of Orthogonal Test in Concrete Corrosion

地下水腐蚀混凝土的研究目前仍以单因素试验为主。本次正交腐蚀试验的主要目的是根据已知的介质组分分析强势的腐蚀因素组合及其主次关系,并可方便地获得各因素对混凝土的腐蚀影响规律。两组复合腐蚀液的试验结果表明,Cl-和Mg2+为强势腐蚀因素;各腐蚀因子之间均存在交互作用,但交互作用强弱不等。在评价腐蚀效应时应综合考虑各腐蚀因子之间的相关关系。

The study of groundwater concrete corrosion test now still takes single factor test. The main purpose of corrosion test is to analyse strong corrosion combination of factors and boats relations which based on known media components, and easy access to all the factors on the concrete effects of corrosion. Two composite etched test results show that Cl^- and Mg^2＋ are the strong corrosion factors. There are interactions between every corrosion factor. It should consider the relationshio of each corrosion factor on evaluation of corrosion effect.
