采用非接触式阻抗测量法(NCIM),研究了水泥浆体的早期水化过程及其在不同阶段的水化行为,并通过Kramers-Kronig变换验证了阻抗数据的可靠性.结果表明:在溶解阶段及动态平衡阶段水泥浆体的阻抗近似为纯电阻;在加速阶段水泥浆体中的阻抗虚部值随着频率的增加而增加;水泥浆体早期抗压强度与其阻抗模数有很好的线性关系.
The non-contact impedance measurement (NCIM) was used to study the early hydration process of cement paste and its hydration behavior at different stages. The reliability of the impedance data was verified by Kramers-Kronig transformation. The results show that, The impedance of the cement paste in the phase and the dynamic equilibrium phase is approximately pure resistance. The imaginary part of the impedance in the cement paste increases with the increase of the frequency in the acceleration phase. The early compressive strength of the cement paste and its impedance modulus are very good Linear relationship.
