Crushing characteristics of a recycled aggregate from waste concrete
The amount of crushed aggregate with a grain size of over 20 mm is approximately 28% and the amount with a grain size in the range 10–20 mm is 72%. After crushing, the size of most of the aggregate was less than 20 mm. Such variation in grain size distribution can be important when recycled aggregates are used for compaction materials.
