Effect of moisture content on freeze–thaw behavior of cement paste by electrical resistance measurements

The electrical resistivity responses of cement pastes with different moisture content under cyclic freeze–thaw (F–T) action are presented. Different moisture content was achieved using water adsorption. Ordinary cement paste samples with water-to-cement (W/C) ratio of 0.5 were used in resistance measurements. Cyclic F–T tests show similar curves of resistivity versus temperature, but with different characteristic parameter values. Depercolation during freezing and repercolation during thawing occur, and the percolation electrical resistivity remains almost constant at around 2000 (
