Three dimensional shape analysis of concrete aggregate fines produced

The sand particles were produced using either a cone crusher or a VSI. The F-shape parameter is defined to be the ratio between the maximal and minimal Feret diameters x Fmax and x Fmin, which are defined by the maximum and minimum distance between parallel tangents in a 2-D particle image projection [27].
