水泥水化过程的电化学研究(Ⅱ)——硬化水泥浆体在直流极化下的交流阻抗谱

Electrochemical Research on the Hydration Process of Cement(Ⅱ) ——ACIS of Hardened Cement Paste under DC Polarization

应用在直流极化下的交流阻抗谱方法测定了水泥水化过程的复平面图 ,在此基础上计算了各电路参数和水化过程的动力学常数 .

The method of ACIS (AC impedance spectroscopy) under DC polarization was applied to study the hydration process of cement. Various dynamic parameters of the hydration process were determined and its mechanism was discussed. It has been shown by Nyquist plot that during the hydration process there exist two different stages in which the microstructure of C S H is quite different.
