摘要
提出了应用交流阻抗谱来研究硬化水泥浆体孔结构的实验方法及其理论依据．通过交流阻抗等效电路中常相角元件的指数与分形几何间的联系，推出硬化水泥浆体孔结构的特征可用分形的维数来表示，得到的结果与用压汞法和ＢＥＴ吸附法的结果相一致．
AC impedance method has been applied to measure the pore structure of different kinds of hardened cement pastes formed at different conditions.Pore structure is characterized by the exponents of constant phase angle elements in the equivalent circuits and hence the fractal dimensions of the samples.The results measured are in good agreement with those obtained by mercury porosimeter and BET adsorption method.
