摘要
摘 要:介绍了一种新型非接触式多通道混凝土早龄期收缩测试设备及测试方法,并用成熟的非接触式电蜗流法与该设备进行测试比对与验证,在验证可靠的基础上测试了矿粉掺量对混凝土早龄期收缩的影响。试验结果表明,非接触式多通道混凝土早龄期收缩测试设备可以准确地观测混凝土早龄期收缩全过程,可以清晰地辨别各个时期的收缩量,且操作简便,并显著提高了试验效率。
Abstract: A new type of non-contact multi-channel test equipment and test methods about the concrete early age shrinkage was introduced. The validation test about the test equipment was carried out with the mature non-contact electrical cochlear flow method. On the basis of validation test, the influence of slag powder content on concrete early age shrinkage was measured. The results show that the non-contact multi-channel test equipment can observe the whole process of concrete early age shrinkage accurately and identify various periods of shrinkage clearly, and also be operated easily, which can improve the test efficiency significantly.
