Abstract: Systems and methods for real-time detecting and quantification of surface and bulk corrosion and erosion in materials involve measuring and characterizing the electrical resistances, capacitances, and/or inductances of the materials and their interfaces, preferably by using an impedance analyzer precision LCR meter. The materials may be metals, non-metals (such as plastics, polymers, cements, concrete, ceramics, rocks and soils) and composite materials with various types of material constituents (such as metals, plastics, polymers, and cements).

Abstract: The chemo-thermo-piezoresistive behavior of so-called “smart cement,” or cement modified with conductive fillers, is useful as a bulk sensor for monitoring the changes in the cement due to stresses, cracks, contamination, fluid loss, and temperature change that affect its performance. The smart cement utilizes a special conductive or semi-conductive filler and is useful as a bulk sensor that allows real-time monitoring of its properties.
