Abstract

The corrosion effect on tensile strength of RC members is very important to region with high corrosion conditions. In this article a study on finding bond behaviour, crack pattern, crack spacing, and tensile strength of RC members is presented. For this purpose a comprehensive experimental program including reinforced concrete cylanders with different concrete covers and reinforcement ratios under various corrosion rates is conducted. The specimens are located in large tub containing water and salt (5% salt solution) with a devich for accelerated corrosion production. For each specimen, the variation of total tensile strength versus its average strain is plotted and the member behaviour at various load levels is investigated. Average crack spacing, and maximum bond stress developed at each corrosion level are studied and their apporoperiate relationship are proposed. The main parameterrs considerd in this investigation are: corrosion rate (C_w), reinforcement diameter (d), reinforcement ratio (ρ), c/d and d/ρ.
