Characterisation of steel reinforcement for RC structures: An overview and related issues

摘要

Characterisation of steel reinforcement is as important as that of concrete ingredients. The paper presents an overview of characterisation along with some related issues. After briefly highlighting the mechanics of RC structures, important characteristics of reinforcement, namely, bond with concrete, strength, ductility, resistance to corrosion are discussed. The effects of manufacturing process on the rebar characteristics are then described. Finally, a comparison of specifications of standards of different countries dealing with reinforcing steel is presented. The authors have suggested certain modifications in the Indian specifications IS 1786.
