  • Abstract The objective of this study is to discuss the application of the ac impedance and vicat needle to the cement paste and water-cement ratio. there are four kinds of equivalent circuit plots in our simulation test.
    The results of our study show that it takes longer for initial setting and final setting if the
    ratio of cement paste and water-cement is higher. besides, it also contributes to the same effect
    if we add more fly ash and slag in the cement paste. furthermore, if the frequency range of the
    fly ash and slag cement paste is fixed at 10000hz, we found that the susceptance of ac
    impedance in our simulation test result will increase. the time is between 0 to 45 minutes and
    it is close to the final setting time in the vicat needle. on the other hand, we also used four
    kinds of equivalent circuit plot in our test, and we found that the results in mode1 and mode3
    are close to the results of our simulation test, and the Rt(s+l)ĦBRs are also positively related to
    the quantities of fly ash and slag that we add in the cement paste.
