WebA sphericity value may be obtained by measuring the long (A), intermediate (B), and short (C) axes of a particle and entering the computer-prepared table with the B/A and C/B ratios. … Web11. apr 2024 · Three types of biowastes (sawdust, grape marc, and grape stalk) and sand were characterized by sieving, and sphericity was calculated using images obtained by scanning electron microscopy (SEM). Sand particles, with a mean diameter of 0.33 mm, were used as inert material. Riley’s sphericity method proved to be the most suitable. rds construct heffen
