Determination of Concrete Reinforcing Bars Characteristics

The objective of this study is to demonstrate the ability to determine the main characteristics of concrete reinforcing bars using simple methods. Most mechanical properties such as yield strength, tensile strength and elongation were determined through the tensile test. The chemical composition was determined using X-Ray Fluorescence (XRF) technique. Three sets of concrete reinforcing bars with diameter 8-20 mm manufactured by different companies were used in those analyses. The results obtained for mechanical properties conform to the specifications values of international standards. The chemical compositions also were in general conforming to the specifications claimed; except that for silicon and manganese which exhibit slightly higher value for some rebars products.
