The process of designing a building structure starts with the selection of construction materials based on their mechanical properties and the type of stresses to be supported. For the design of reinforced concrete structure, which is one of the most built structures around the world, the choice will fall on concrete and steel reinforcing bars. The quality of TMT (Thermo-Mechanically Treated) bars chosen must have adequate tensile strength to guarantee a ductile behaviour expected of reinforced concrete structure, so that the structure will be safe and functional to fulfil the purpose for which it is built. Possible causes of the failures of reinforced concrete structures are many including the quality of steel and concrete adopted. In this research work, various quality assessment tests such as Ultimate Tensile Strength test, Bend & Re-band test and Elongation have been performed on TMT steel reinforcing round bars used in local areas of Assam. Samples of 10 mm, 12 mm and 16 mm diameter bars of different brands namely JINDAL, SATYAM, TISCON and VISCON were collected from different stages of construction, including reinforcement procurement and onsite storage of Jorhat district and tested in the Material Testing Laboratory, Civil Engineering department of H.R.H. The Prince of Wales Institute of Engg. & Technology, Jorhat, Assam. Results obtained shows that all the samples considered met the IS 1786 (2008) code specifications.
