recycled concrete aggregates (RCA) [4]. Initially, the recycled aggregate (RA) was used for non-structural purposes such as fill material, base course material and foundations, however, modern research has shown that it is viable option to use recycled concrete aggregates to replace natural aggregates (NA) in structural concrete.

Flexural strength of recycled aggregate concrete showed similar trends like the other properties. Studies shown that the flexural strength using recycled concrete aggregates varied by 16-23% with different replacement levels [41]. Hansen (2014) stated that using RCAs in the SSD state compensates for the workability loss in the mix [42].
