用交流阻抗谱法测定了不同水灰比普通硅酸盐水泥净浆水化反应的阻抗谱,实验结果表明:(1)不同水灰比样品复阻抗实部曲线具有相同的变化趋势,即随着水化反应的进行,复阻抗实部曲线均呈现出减小→增大→减小→增大的变化规律;(2)特征点的出现时间随水灰比的增大依次延后,特征点的时间间隔均随水灰比的增大而变大;(3)在硬化期,低水灰比水泥净浆阻抗谱实部曲线有较大的增长斜率;(4)阻抗谱实部和阻抗谱虚部曲线的变化趋势相反,并且在同一次实验测量中,阻抗谱实部和虚部曲线特征点并不对应同一测量时间.
用交流阻抗譜法測定瞭不同水灰比普通硅痠鹽水泥淨漿水化反應的阻抗譜,實驗結果錶明:(1)不同水灰比樣品複阻抗實部麯線具有相同的變化趨勢,即隨著水化反應的進行,複阻抗實部麯線均呈現齣減小→增大→減小→增大的變化規律;(2)特徵點的齣現時間隨水灰比的增大依次延後,特徵點的時間間隔均隨水灰比的增大而變大;(3)在硬化期,低水灰比水泥淨漿阻抗譜實部麯線有較大的增長斜率;(4)阻抗譜實部和阻抗譜虛部麯線的變化趨勢相反,併且在同一次實驗測量中,阻抗譜實部和虛部麯線特徵點併不對應同一測量時間.

The impedance spectra of different water-cement ratio of ordinary portland cement hydration reaction was obtained in this paper, and the experimental results showed that: (1)The real part of complex impedance of the sample with different water-cement ratio has the same trend of increase, which shows decrease - increase - decrease - increase; (2)The feature points delays successively with the increase of water-cement ratio, and the time interval of the feature points enlarges with the increase of water-cement ratio; (3)The real part of complex impedance of the sample with low water-cement ratio has a much larger increase slope in the hardening period; (4)The variational trend of the real part of impedance spectra is quite opposite from the imaginary part, and the feature point of the real and imaginary part of impedance spectra does not appear at the same time during once measurement.
