The electrical conductance and hydration kinetics of artificial pozzolana-cement pastes
Artificial pozzolana were made by firing of two types of clays at two temperatures (600 deg C and 700 deg C). Different artificial pozzolana-Portland cement pastes were made using a water/cement ratio of 0.40 by weight of the cement blend. Each cement paste was examined for hydration kinetics at 20 deg C as well as electrical conductance at 20 and 35 deg C. The results of hydration kinetics indicated a sort of phase transformation of hydration products at the intermediate stages of hydration. Electrical conductance studies demonstrated two maxima at 20 deg C; only one maximum at 35 deg C was detected at the early stages of hydration. All results could be related to the sequence of the initial hydration reaction and the mode of disruption of the electrically insulating coating layers around the grains of the cement constituents.
