Crushing characteristics of a recycled aggregate from ...

2018-1-30 · A crushing load reduction ratio for determining natural aggregate crushing is proposed. The load reduction ratio was over 50% for 63% of natural aggregate crushing cases. After crushing, the size of most of the aggregate was less than 20 mm, which can influence the compaction efficiency and friction behavior of recycled aggregates.
