Abstract

In this study, capacitance based self-sensing properties of the cement paste is investigated. Continuous and discontinuous loading cycles (minimum stress is 6 kPa, maximum stress is 36 kPa) are applied to the cement pastes. A correlation between stress and capacitance is observed. The greeter the compressive stress on the cement paste, the lower the capacitance. Capacitance change is irreversible for the entire stress regime. Initial capacitance value (un-loaded state) of the cement paste is 119.51 pF, whereas capacitance value of the specimen under 36 kPa compressive stress is 119.41 pF. Fractional change in capacitance at the highest stress is 9.2x10-4.
