1. Its fine particle sizing ( nonplastic silt ) and spherical particle shape enhances mix flowability . 2. The cement powder flowability is reduced, and air-set lumps tend to form. 3. "The flowability of the glaze doesn't seem to be as good," 4. A Hausner ratio greater than 1.25 is considered to be an indication of poor flowability . 5. The Carr index is frequently used in pharmaceutics as an indication of the flowability of a powder. 6. For higher-strength concrete, lower ratios are used, along with a plasticizer to increase flowability . 7. The Hausner ratio is used in a wide variety of industries as an indication of the flowability of a powder. 8. Additional features include excellent wet abrasion resistance, easy melt flowability ( shear thinning ), and good dispersion of fillers. 9. A Carr index greater than 25 is considered to be an indication of poor flowability , and below 15, of good flowability. 10. A Carr index greater than 25 is considered to be an indication of poor flowability, and below 15, of good flowability .
