Effect of temperature on electrical conductivity of blended cement pastes
Previous studies proved that addition of slag and silica fume to ordinary Portland cement increases the chemical resistance to aggressive ion attack and results in lowering of the heat of hydration. In this investigation, the effect of curing temperature on the hydration characteristics of blended cement was studied. The blended cement used in this investigation consists of ordinary Portland cement, slag, and silica fume. The change in phase composition of cement pastes was investigated by differential scanning calorimetry. The electrical conductivity of cement pastes was monitored during setting and hardening at different temperatures. It is demonstrated that the electrical conductivity of cement paste can be used as an effective means of studying the progress of cement hydration and for monitoring structural changes occurring within the paste. The setting time of blended cement changed according to curing temperature.
