Abstract

The project has as its goal the development of the prototype of a compact version of a system for the inductive scanning of steel bars in concrete structures, producing 3D images starting from a beta version already developed, which produces 2D images. At the end of phase 2 of the project, it is intended to have the first version of a device of wide application in the civil construction industry, as well as in other sectors. Today there is greater concern about the safety of concrete structures than before. One of the most important aspects in such structures is the condition of the steel reinforcements. Considerable resources are being spent on research to develop tests on the destructibility of such components. The magnetic scanner is the most advanced instrument for the inspection of concrete structures, providing a magnetic image of the metallic structures. This project intends to make available to the Brazilian market a complete system, including a magnetic scanner and controller, data acquisition, software for viewing, processing and analysis of the image of the concrete, as well as instruction manuals.
