Correlation of electrical measurements with moisture content for the diagnosis of preservation levels of neapolitan traditional masonries and the determination of recovery interventions

The humidity phenomena leads to the deterioration of walls’ performance. The recovery project relies on prior knowledge of the existing preservation levels. Innovative studies are exploring non-destructive electrical diagnosis methods to determine moisture contents and the correlation with measured electrical parameters. The research presented in this paper modifies the traditional methodological approach and defines a method for measuring the performance levels of wet tuff masonry. This method is based on comparing electrical measurements conducted in the laboratory. The innovative approach allows measurements to be taken without the constraints of probes design and external interference, overcoming limitations of current applications.
