研究了分别在NaCl和CaCl2·2H2O盐水溶液中浸渍7－730d的水泥砂浆试件受氯离子渗透的现象试验中，用染色法和滴定法先后测定了氯离子的渗透深度及其在渗透方向上的含量变化结果给出了渗透深度与水泥标号、水灰比、养护龄期、盐水溶液氯离子载体种类、氯离子浓度和试件浸渍时间等实验参数的关系，以及水泥砂浆的氯离子总含量和游离分量沿渗透方向的变化，并用滴定的结果对染色得到的分离子渗透深度进行了评价． The test of penetration of chloride ions by cement mortar specimens impregnated with NaCl and CaCl2·2H2O aqueous solutions for 7-730 d was studied. The depth of permeation of chloride ions and their permeation directions were determined successively by dyeing and titration. The results of the content change give the relationship between penetration depth and experimental parameters such as cement number, water-cement ratio, curing age, type of chloride ion carrier, chloride ion concentration, and sample impregnation time, and the total chloride ion content of cement mortar. The change of the free components along the infiltration direction and the results of the titration were used to evaluate the penetration depth of the separated segregants.
