Chlorides concentration and ph measurement of concrete structure through immersed sensors

Abstract

The present work develops non-destructive measurements of chemical-physical parameters of concrete, in order to evaluate the degradation condition and to monitor, in time, the aging process. This study in particular focuses on the measurement of parameters such as pH, and therefore the carbonatation level of the concrete, and salt concentration (i.e. chlorides), and the evolution of these quantities with time. The analysis can be extended to other chemical-physical parameter of interests for which is provided a specific microsensor.
