Durability Studies on the Recycled Aggregate Concrete in

At the present stage, the C&D wastes are frequently used to produce the recycled aggregates (RA), which include the recycled fine aggregate (RFA) and recycled coarse aggregate (RCA). Furthermore, recycled aggregate concrete (RAC) can be prepared by replacing the natural aggregates (NA) with RA in concrete [8, 9].

Durable Performance of Recycled Concrete Using Coarse

The influence of synchronous use of coarse and fine recycled concrete aggregates on durable performance of recycled aggregate concrete (RAC) in air environment were determined. In this study, three series of concrete mixtures were prepared, in which the coarse recycled aggregate was used as 0%, 30%, 60% and 90% replacements of coarse natural aggregate and fine recycled aggregate as
