The d.c. conductivity, ~, and low-frequency relative dielectric constant, k, of Portland cement paste were monitored, using impedance spectroscopy, during cooling from room temperature down to -50 ~ Dramatic decreases in the values of ~ and k, as great as two orders of magnitude, occurred at the ini
Surface corrosion of reinforcing steel embedded in cementitious materials containing chloride ion is described by characteristic change of impedance spectra. Phase angle shift, surface impedance and capacitive responses, recorded at very low frequency (100Hz-10mHz), are demonstrated to be very sensi
