WebAug 23, 2024 · Classification of Coarse-Grained Soil (Based on ISSCS) According to the IS soil classification system, coarse-grained soil is graded based on particle size, gradation characteristics (Cu and Cc), and percentage fineness. The soil in which 50% or more soil particles are retained on a 75-micron sieve (0.075 mm) is classified as coarse-grained soil. WebThe values of C u and C c are used to classify whether the soil is well-graded or not. Sand isconsidered well-graded, if C u is greater than 6 and C c is between 1 and 3. For gravel to be considered as well-graded, C u should be greater than 4 and C c should be between 1 and 3. From Figure 3.5, D 10 = 0.18, D 30 = 0.35, and D 60 = 0.61 country music awards austin tx

Soil gradation is a classification of the particle size distribution of a soil. Coarse-grained soils, mainly gravels or sands, are graded as either well graded or poorly graded. Poorly graded soils are further divided into uniformly-graded or gap-graded soils. Fine-grained soils, mainly silts and clays, are classified according to their Atterberg limits.
