Effect of Crusher Operation on Coarse Aggregate Shape

Subtle differences in coarse aggregate shape can cause major differences in the properties of the concrete. Operation of the crushing equipment at the aggregate source has an effect on the shape of aggregate particles. A cubical particle shape is obtained when a large part of the crushing work is accomplished by interparticle contact.

Investigation of the Effects of the Type of Crusher on

The fundamental shape/morphological properties of coarse aggregates including form, angularity, and surface texture are known to influence the performance of pavements. The coarse aggregate shape properties are affected by many factors, amongst others, the properties of the parent rock and the type of crusher or crushing operations.
