A comprehensive probabilistic model of chloride ingress in unsaturated concrete
Corrosion induced by chloride ions becomes a critical issue for many reinforced concrete structures. The chloride ingress into concrete has been usually simplified as a di↵usion problem where the chloride concentration throughout concrete is estimated analytically. However, this simplified approach has several limitations. For instance, it does not consider chloride ingress by convection which ...
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 کاملAutogeneous healing and chloride ingress in cracked concrete
An experimental study of the influence of autogeneous healing on chloride ingress in cracked concrete is presented. In the study, two concrete mixtures (a Portland cement mix and a blast furnace slag mix), two healing regimes (submerged and fog room regime), two cracking ages (14 and 28 days), and multiple crack widths are used as parameters. An adapted Rapid Chloride Migration testing procedur...
متن کاملInfluence of weather and global warming in chloride ingress into concrete: a stochastic approach
Reinforced concrete (RC) structures are subject to environmental actions affecting their performance, serviceability and safety. Among these actions, chloride ingress leads to corrosion and has been recognized as a critical factor reducing the service life of RC structures. This paper presents a stochastic approach to study the influence of weather conditions and global warming on chloride ingr...
متن کاملControlling chloride ions diffusion in concrete
The corrosion of steel in concrete is mainly due to the chemical reaction between the chloride ions and iron ions. Indeed, this is a serious threaten for reinforced concrete structure, especially for the reinforced concrete structure in the sea. So it is urgent and important to protect concrete against chloride ions corrosion. In this work, we report multilayer concrete can cloak chloride ions....
