Analysis of shape parameters of coarse aggregate and their effects on packing density by DIP technique

Abstract

In this paper the particle shape parameters are analysed using a sophisticated technique called Digital Image Processing (DIP). The effects of shape parameters on the packing density are studied. The packing density determines the amount of cement paste required to fill the voids between aggregate particles. In this paper the details of experimental investigations carried out on coarse aggregates are presented. Aggregate samples from seven different sources have been used for experimental investigation. The shape parameters determined by DIP technique are correlated with packing density.
