Submitted by admin on Sun, 2015-09-13 05:00. uniformity coefficient (u-ni-form'-i-ty). A numerical expression of the variety in particle sizes in mixed natural soils, defined as the ratio of the sieve size through which 60% (by weight) of the material passes to the sieve size that allows 10% of the material to pass.

Answer 2

The coefficient of uniformity or the CU is the ratio of the D60 by D10, if the ratio is greater than 4, then the soil is considered as good quality soil. ... On the other hand, the coefficient of curvature is the ratio of (D30)2/(D10.
