【摘要】 结合室内试验及现场试验所测得的氯离子浓度分布,与Fick第二定律给出的氯离子浓度分布曲线进行比较,分析了不同侵蚀环境下氯离子浓度分布的特点并计算了其与Fick分布两者间的相关性。结果表明,Fick第二定律适用于室内试验环境、现场盐雾作用环境和海水浸泡环境,经适当修正后,还可适用于有碳化或硫酸根影响的环境,但不适用于海水反复淋溅作用下的环境。更多还原

【Abstract】 Compared with two Cl- distributions, the testing mearsurements in laboratories or in sites and the calculated valumes byFick′s second law, the correlation coefficients of two distribution curves are calculated and analysed. The rezults show that, the Fick′s sec-ond law is suitable for indoor tests and under the conditions of salt- fogging or seawater- immersion, and after a proper correction also suit-able for suffering of carbonation and sulphate attack, but dose not suited for the environments of repeatedly spraying of seawater.更多还原
