    Abstract

    The corrosivity of different types of soil have been assessed by exposing carbon-steel plates at 50 different locations in Denmark for an extended period of time. The investigations included weight loss measurements and analysis of the chemical compositions of the corrosion products formed on the plates during exposure. An electrochemical soil corrosion probe has been designed and manufactured allowing for simultaneous measurements of several qauntities to predict corrosion. The probe consists of individual sections capable of measuring redox-potential, corrosion potential, soil resistivity and hydrogen absorption rates. In addition, traditional carbon-steel 3-electrode arrangements allow for performance of any kind of electrochemical meaurement (EIS, polarisation curves, LPR-measurements, galvanostatic pulse etc.).
