dc.description.abstractThe incessant building collapse and structural failures in Nigeria has renewed interests in the evaluation of the basic properties of reinforcing steel bars in Nigeria markets, since local markets serve as major source of supply for the steels used in construction and structural development. Thus, this study evaluated the quality of commercially available reinforcing steel bars in some selected markets with a view to determine their suitability for structural applications. Various steel bars samples were obtained from markets in four Nigeria cities. The basic physico-mechanical properties of the samples were examined and the obtained results were compared with the specified parameters in Nigerian Industrial Standard (NIS), ASTM and British Standards. Visual inspections revealed that most of the parameters that must to be indicated in identification marks on reinforcing steel bars were absent. Results also showed that the samples contained the basic chemical constituents of steel and possessed significant strengths and hardness values, but with noticeable inconsistencies in their contents. Thus, the level of compliance with the specified properties in the standards needs improvement. To avoid incessant structural failures in the country, regular and effective monitoring of the quality of steel bars in the markets for structural applications becomes imperative.en_US
