Understanding Effects of Crushing Mechanism on Aggregate Morphology
For given aggregate type, the associated crushing mechanism plays a decisive role in governing morphology of aggregates. The crushing of aggregates involves three prime mechanisms, namely abrasion, cleavage and impact . The abrasion can only induce localised stress in a small fragment of total surface area and result in limited size reduction.
