چکیده انگلیسی
This paper aims to evaluate the applicability and suitability of the different methods, including weight loss, vernier caliper, drainage method, 3D scanning and XCT methods in the measurement of geometric parameters and amount of corrosion of a steel bar. A single 400 mm long and 14.11 mm diameter steel bar was measured first as non-corroded specimen before an accelerated corrosion of its 300 mm long middle part took place. This was followed by the measurement and evaluation of the geometrical parameters of the same bar specimen within its 300 mm long corroded part and 30 mm non-corroded part at its right end using different methods. The results show that the geometrical parameters of a corroded bar measured using 3D scanning and XCT methods well matched each other and much more precise than those using weight loss, vernier caliper and drainage methods. 3D scanning is the most suitable method to measure the geometrical parameter of a corroded bar. Vernier caliper is the best option for measuring the geometrical parameter of a non-corroded bar.
