| چکیده | ||
| For rehabilitation of damaged concrete structures, the durability of repair overlay is a very important issue. Self-compacting concretes (SCC) are known as a suitable repair overlay materials. In this study, the durability of different self-compacting lightweight aggregate concretes (LWSCC) and effect of lightweight aggregate type on them is investigated. 3 mix designs of LWSCC containing three different types of lightweight aggregates and a conventional self-compacting concrete were considered. The Rapid chloride permeability tests (RCPT), Rapid chloride migration tests (RCMT) and Accelerated corrosion tests (ACT) were performed and the Chloride migration coefficients were obtained. The corrosion resistance of the mix designs was investigated and compared. The resistance against chloride penetration were acceptable for all mix designs, but concrete with Leca and Pumice had the best and the worst performance respectively. As a result of using lightweight aggregates, using Scoria aggregate may cause better protection to steel reinforcement against corrosion than Leca and Pumice aggregate. | ||
