| 摘 要： | 研究了不同矿物掺和料在干燥或浆体状态下的交流阻抗谱,通过比较其差异对矿物掺和料的水合过程机理进行了探讨.结果表明:矿物掺和料的阻抗值在电介质范围内,但其Cole-Cole图与一般的电介质不同,矿物掺和料的水合过程较水泥的水化过程简单,但也存在初凝阶段和终凝阶段.

| Abstract: | Impedance spectra of a variety of mineral admixtures in dry state as well as in aqueous paste were shown with a view to comparing the difference among them and elucidating the mechanism of their hydration process.It is shown that the impedance of mineral admixture is in the range of dielectrics,however,their Cole-Cole plot is quite different from the ordinary dielectrics.Though there exit the stages of initial and final setting in the hydration process of mineral admixtures,it is far simpler than that of cement. |
