Uniformity Coefficient(Cu) and Coefficient of Curvature(Cc) of Soil
Hence, D10, D30 and D60 are used to determine the measures of gradation. Measures of Gradation. The uniformity coefficient (Cu) and the coefficient of gradation (Cc) are the measures of soil gradation. These coefficients help to classify the soil as well graded or poorly graded ones. Uniformity Coefficient (Cu)

Soil Gradation Plot
Soil gradation is an important aspect of soil characterization that represents the distribution of different particle sizes in a soil sample. Plotting soil gradation involves using the results of a sieve analysis, which is a laboratory test that separates soil particles based on their sizes by passing the sample through a series of sieves with varying opening sizes.
