Durability Design, Monitoring and Rehabilitation

The durability of the concrete structures, monitoring and rehabilitation is a major concern all over the world. Extensive studies have been carried out to improve the quality of concrete by using different materials, but the current knowledge in this area is still insufficient. The demands of better quality concrete by its users are ever increasing. Therefore, it is very important to meet their expectations by improving the quality of concrete structures as well as enhancing monitoring and mitigation methods. If the concrete properties related to durability can be increased, then service life of concrete structures can also be increased. There are so many factors which decreases or increases the quality of concrete, such as quality of mixing water, water/cement ratio, quality of aggregates, environmental factors (coastal, industrial and non-polluted area), workmanships, and so on. During the service life of concrete structure, monitoring material serviceability and durability is critical in extending structural service life. The durability of concrete can be explained on the basis of tolerance of weathering condition towards resistance to deterioration by chemical attack, thawing, abrasion, etc. However, if the structures start to deteriorate, then its mitigation procedure by using different protective schemes can be assessed. Therefore, this special issue emphasizes the quality of concrete using nano-technology, advanced materials, monitoring and rehabilitation procedures, etc.
