Concrete Carbonation and Chloride Resistance Under Initial Hot Water Curing
Three concrete mix proportions were designed and prepared, respectively, such as fly ash concrete (abbreviated as “FAC”) with 30% fly ash replacement ratio of cement, fly ash, and slag concrete (abbreviated as “FSC”) with each of 20% fly ash and slag replacement ratio and ordinary Portland cement concrete (abbreviated as “OPC”) for the research of carbonation and chloride resistance of concrete...
متن کاملProgress of Carbonation in Chloride Contaminated Concretes
Concretes used in marine environment are generally under the cyclic effect of CO2 and chloride ions (Cl -). To date, the influence of carbonation on ingress of chloride ions in concretes has been widely studied; in comparison, study on the influence of Clon the progress of carbonation is limited. During the study, concretes were exposed to independent and combined mechanisms of carbonation and ...
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 کاملA 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...
