Abstract

Conductivity and permittivity of Type I, II and III cement pastes have been measured during the first 24 h hydration period at 10.0 GHz using the infinite sample method. Correlations between the electrical parameters and the chemical processes are discussed. Conductivity and relative permittivity are shown to be affected by the water-cement ratio and the type of cement. Changes in electrical parameters during the hydration processes coincide with hydration stages as derived from calorimetry measurements.
