ERT Imaging of Graphite Electrically Conductive Concrete

Article Preview

Abstract:

In recent decades, Electrical Resistance Tomography (ERT) has become a research focus. The application of ERT in practical engineering is still in the research stage, due to the resistivity is very high and not steady, limiting its development. The influencing factors of Graphite Electrically Conductive Concrete (GECC), such as the dosage of graphite, curing age, moisture content and so on, have been analyzed. A set of ERT system of GECC has been proposed and designed based on PXI platform. This paper mainly shows experiments on ERT of GECC structure. The targets given with defects have been used for imaging. By examining, the law of the GECC imaging in different conductivity matrix has been got. Meanwhile, this paper determines the resistivity threshold in the ERT system, and validates the detection accuracy of the model with defects.
