Understanding Effects of Crushing Mechanism on Aggregate …
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. Cleavage is the application of compressive stress on aggregate, which prompts a limited number of …
