Corrosion of Reinforcing Bars Astm A706 in Self-Compacting Concrete Subjected to Chloride Attack and Carbonation
Self-compacting concrete is characterized as a system that has a mix design that increased strength and reduced amount of empty space within material. Reinforced concrete structures exposed to carbonation and chloride ion, are exposed to environmental conditions that cause degradation. Concrete were exposed to an accelerated carbonation test (3% CO2, 65% relative humidity, and 25 o C temperatures) and next it was tested under complete immersion, in 3.5 wt. % NaCl solution. . Monitoring of open-circuit potential, polarization resistance measurement and electrochemical impedance spectroscopy were used to evaluate the corrosion behavior of steel bar.
