Study of the factors affecting the electrical conductivity of zinc–polycarboxylate cement

摘要

AbstractThe behavior of the electrical conductivity of polycarboxylate cement with temperature was studied from room temperature up to 160°C. 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
