The study was undertaken to compare shape parameters of fine aggregates produced from three different crushers, i.e. vertical shaft impactor (VSI), cone crusher (CC) and horizontal shaft impactor (HSI).
The comparison between Conventional and Digital Image Technique based shape characterization approaches are presented.
