水泥基材料水化过程的交流阻抗研究

Study of the Hydration Process of Cement-based Materials by AC Impedance Technique

用交流阻抗谱方法对水泥净浆、砂浆和普通混凝土的水化过程机理进行了研究 ,从不同龄期的交流阻抗谱的特征出发 ,对水泥基材料的水化过程进行了分期 ,并按照水化过程中水泥基材料与水的结合形式对水化进行了分类 。

The mechanism of the hydration process of cement paste, mortar and ordinary concrete has been studied by AC impedance technique. Different stages of the hydration process of cementbased materials were classified by the characteristics of the impedance spectra. The hydration of cementbased materials were also classified as primary, secondary and tertiary according to the binding form of the material with the water. The negative capacitance occurring in the initial and early stages of hydration has been interpreted from the viewpoint of structure.
