Pitting Corrosion Behaviour of New Corrosion-Resistant Reinforcement Bars in Chloride-Containing Concrete Pore Solution
In this study, the pitting behaviour of a new corrosion-resistant alloy steel (CR) is compared to that of low-carbon steel (LC) in a simulated concrete pore solution with a chloride concentration of 5 mol/L. The electrochemical behaviour of the bars was characterised using linear polarisation resistance (LPR) and electrochemical impedance spectroscopy (EIS). The pitting profiles were detected b...
متن کاملEmbedded Capacitor Sensor for Monitoring Corrosion of Reinforcement in Concrete
Corrosion of reinforcement can affect durability and integrity of reinforced concrete structures. Repair cost for a badly corroded structure can be very costly and time consuming. In this paper, several capacitor sensors were developed to monitor corrosion potential of reinforcement in concrete. The impedance capacitive of sensors was tested in various acid and alkali solutions using Agilent 42...
متن کاملChloride Ingress Resistant Concrete: High Performance Concrete Containing Supplementary Composites
1 Associate Professor of Structural Engineering College of Engineering, King Saud University Email: [email protected] Abstract – In Reinforced concrete structures chloride ion penetration is considered to be a major cause of corrosion of reinforcing bars. Conventional concretes fail to prevent the intrusion of moisture and aggressive ions adequately. The use supplementary cementing composite ma...
متن کاملModeling of Chloride Concentration Effect on Reinforcement Corrosion
The corrosion of reinforcement is one of the major causes of deterioration of reinforced concrete (RC) structures, considerably affecting their durability and reliability. The rate of reinforcement corrosion is governed by, among other factors, the presence of chlorides on the surface of the steel. The assessment of such deteriorating effects necessitates the development of relevant models and ...
متن کاملTHESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Chloride Induced Corrosion of Reinforcement Steel in Concrete Threshold Values and Ion Distributions at the Concrete-Steel Interface
The chloride threshold value (Cth), or critical chloride content, is defined as the chloride concentration at the depth of the reinforcement, which initiates the depassivation of steel in concrete. However, very limited information is available regarding the chloride distributions at the interface with the steel. The main objective of this work is to improve the knowledge and understanding abou...
