Rapid assessment of the potential chloride resistance of structural concrete
This present study benchmarked the chloride resistance of concretes mixes at the limit state of BS 8500-1:2006 using the newly published CEN TS12390-11. Of the three allowed methodologies, the immersion test was carried out. At least two water-cement ratios were produced for each mix design to …

Enhancing the service life of concrete exposed to chloride attack
… to enhance the durability of concrete exposed to chloride attack by means of two approaches: (i) to design sustainable concrete compositions and (ii) to apply suitable maintenance techniques consisting of electrochemical chloride extraction (ECE) and surface coating (SC) treatments. Subsequently, …

Assessment and prediction of chloride ingress and carbonation in patch repair mortars
… performance requirements, such as carbonation resistance and chloride resistance, are usually not considered despite the fact that they have a direct influence on the durability performance of concrete repair mortars. The widespread premature failure of patch repairs which meet the existing …

Evaluation of surface treatments for RC structures failing to meet South African durability index requirements
… of corrosion causing agents (carbon dioxide, chloride ions and moisture) is presented in literature but the extent of protection and durability of these products is largely unknown. A laboratory investigation was developed to evaluate the performance and longevity of surface treatments under …

Role of cement content in determining resistance of concrete to reinforcement corrosion
… relationships between cement content and resistance of concrete to carbonation-andchloride- induced reinforcement corrosion. Moreover, no data were found on the combined influences of crack width and cement content on resistance of concrete to reinforcement corrosion.Given this background, …

Durability Assessment and Service Life Prediction of Concrete in Extreme Aggressive Environment
… the performance of various concrete mixes for chloride resistance. The study focuses on establishing and developing correlations between chloride diffusion rates and concrete resistivity. By identifying these correlations and based on the target service life, the research aims to set …

Influences on durability and leaching behaviour of concrete: new technologies in fly ash production
… showed that finer, low LOI fly ashes had higher chloride resistance and at equal strength fly ash concretes performed better than those with PC. Equal strength fly ash concretes covering the modern technologies were found to have similar levels of durability for sulfate attack, abrasion and …

Chloride penetration in concrete: evaluation of rapid conductivity methods and development of a service life prediction model for marine conditions
Chloride-induced corrosion is the predominant cause of loss of service life in reinforced concrete structures subjected to marine conditions. To protect reinforcing steel from the corrosive effects of external chloride ions present in these environments, a proper combination of concrete quality and …
