Crushing treatment on recycled aggregates to improve
In both series different samples of RA were processed by sieving, crushing and compaction in different ways. In addition, natural aggregate samples were studied to compare with recycled ones. The results show that the influence of the treatment in the material, mainly crushing and fresh compaction, as well as particle size, significantly ...
