recycled aggregate durability

Durability of recycled aggregate concrete - ScienceDirectThis paper presents the main results of the research carried out to analyse the physical, mechanical and durability properties of concrete incorporating recycled aggregate. One of the most unknown aspects of recycled aggregate concretes is related to their durability in aggressive environments. Also most of the results.recycled aggregate durability,recycled aggregate durability,Durability of Recycled Aggregate Concrete: A ReviewMar 1, 2017 . For non-structural applications, recycled aggregate concrete has been widely accepted in several countries mostly in Japan. However, further studies on its durability are still required. The lack of comprehensive standard guidelines for mixture proportion as well as the limited studies on its durability has.
