应用交流阻抗方法研究了水泥浆体 /粗集料的界面性质 .从交流阻抗参数的变化可以了解浆体 /集料界面的结合力和抗渗性随浆体组成、集料品种以及养护时间的变化 .
The interfacial properties of cement paste / coarse aggregate were studied by means of AC impedance method. From the change of AC impedance parameters, it was found that the bond strength and impermeability of the aggregate / aggregate interface changed with the composition of the slurry, aggregate variety and curing time Variety .
