“…The temperature dependency of conductivity can be empirically written as (Bockris and Reddy 1970;Sawaby et al 1988;Whittington et al 1981): or vice at fixed frequencies and recommended in the proposed testing method. In other words, the advantage of using the a-c impedance spectroscopy is to obtain a spectrum of impedance with a broad range of frequencies so that the low-frequency intercept impedance can be accurately detennined.…”

SynopsisThe behavior of the electrical conductivity of polycarboxylate cement with temperature was studied from room temperature up to 160OC. The effects of powder/liquid ratio, mixing temperature, percentage of MgO in the powder, and aging on this behavior were also investigated. The results obtained revealed that the electrical conductivity decreases with increasing the powder/liquid ratio and with decreasing mixing temperature and the amount of MgO in the powder. The reason for the changes of the conductivity due to the mentioned factors were discussed.
