    This paper describes the use of electrical property measurements to study physical and chemical changes occurring within cover-zone concrete during the early stages of hydration (up to 28-days). Concrete samples with different mix proportions have been embedded with sensors which are capable of measuring spatial and temporal changes in electrical resistance and temperature of the concrete. The results obtained from different concrete mixtures indicate that the water-binder ratio and both the dosage and type of mineral admixture influence the measured electrical conductivity and temperature within the cover-zone. Results can be interpreted in terms of setting, hardening and strength development. Furthermore, the changes observed in the electrical conductivity could also be used to evaluate drying effects and the convective zone.
