摘要
对钱塘江河口地区感潮环境下的既有混凝土芯样中的氯离子浓度进行测定,分析侵蚀深度与氯离子浓度的关系。根据既有混凝土样本,测定既有混凝土的孔隙率,并分析氯离子扩散控制起点与孔隙率之间的关系。另外,同一深度的氯离子浓度具有较大的随机性,而且较好地符合对数正态分布。
The chloride ions＇ concentrations in existing concrete in tidal estuary environment of the Qiantang River are measured, the relation between erosion depths and concentrations of chloride ions in concrete is a analyzed. Based on the samples, the porosities of existing concrete are measured, and the relations between control starting points and porosities is also studied. In addition, there is stronger randomness in distribution of chloride ions＇ concentration at the different depths of existing concrete.
