混凝土中氯离子渗透性测定的电化学方法

Electrochemical Methods for the Measurement of Chloride Permeability in Concrete

本文提出了三种测定氯离子在混凝土中渗透性的简易的电化学方法，可用来代替较为复杂的ＡＳＴＭ建议的电学方法。方法简单省时，可靠性好，其中两法可用通用的电化学仪器进行测量，另一方法可以得到关于影响渗透性的各因素的信息。

Three electrochemical methods,i.e.chronoamperimetric (CA),cyclic voltammetric(CV) and AC impedance methods have been proposed to replace the method of AASHTO proposed by ASTM.It has been shown that CA and CV methods are far simpler and easier than that of AASHTO with the same precision and reliability.AC impedance method will give information about resistance and diffusion of ions in pore solution which are correlated to chloride permiability.
