A prototype for water content measurement in partially saturated soils

The paper presents the technological set-up and calibration of a system based on impedance spectroscopy for measuring water content in partially saturated soils. technique adopted is relatively recent geotechnical practice; it used herein to characterize electrical response soil specimen among two conducting electrodes upon application an alternate voltage measurement current intensity resulting across specimen, frequency values range [500 Hz – 50 kHz]. complex due both resistance, i.e. opposition current, reactance, tendency yield retrieve energy, depends content. An on-purpose experimental plan has been conceived presented herein, aimed at building function deriving pyroclastic soils from measurements. Preliminary results reveal adequate level repeatability measurements suggest existence monotonic correlation between modulus gravimetric
