Abstract
Corrosion resistant steel (CRS) are used in the const-ruction work of Narmada Canal Project due to high level of salinity, sulphate and other ions present in parts of Gujarat. The rebar samples collected from different sites of the construction work were sent to NML for evaluation of their physical, chemical and corrosion properties evaluation in order to decide suitability for their use in construction work of Narmada Canal. The composition of the bars were analysed chemically. Bending and Tensile tests were performed to determine yield, elongation, tensile strength and crack after 90o bend. The CRI values in diff-erent environment and pitting resistance in concrete pore solution containing NaCI were determined. The chemistry, physical properties and corrosion resistance were found as per requirement except 10 and 12mm dia of lot no. III and IV.
