| 摘 要： | 基于ASTM C1202规范,研制了基于计算机USB总线的混凝土抗氯离子渗透性测定仪。该设备具有自动化程度和精度高、安全性强、可移植性和可扩展性强的特点。实验结果表明:随着混凝土水胶比的降低,其抗氯离子渗透性增强;同时,在相同的测试时间点,抗氯离子渗透性较高的混凝土试样端部盐池溶液的温升也较低。

| Abstract: | Concrete chlorine ion penetration resistance measuring instrument based on the USB bus of computer system was developed according to the ASTM C1202 specification.Compared with the testing set given by the specification,this instrument has the characters of automation,high accuracy,security,transplantability and extensibility.Experiment results show that with the decrease of ratio of water to binder,the concrete chlorine ion penetration resistance is enhanced and that the salt solution temperature rise of concrete with higher chlorine ion penetration resistance is low with lower chlorine ion penetration resistance at the same testing time interval. |
