WebMar 24, 2024 · Uniformity Coefficient (UC) – This is defined as a ratio and is calculated as the size opening that will just pass 60% of the sand (d60 value) divided by the size opening that will just pass 10% of the sand sample (d10 value). ES is basically a value describing the average size of sand grains in a sand sample. WebMay 12, 2024 · Coefficient Of Curvature. It is the parameter estimated using the gradation curve through sieve analysis. This parameter is used to classify the soil as well graded or poorly graded and is given by the relation as below. Here, the term C u is coefficient of uniformity, D 30 is grain diameter below which there are 30% of particles present in the.

WebFor resins with uniform particle size, the median diameter, harmonic mean size and effective size are close to each other.
