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.

WebExplanation: The well-graded soils are the soils in which there is a wide variation of particle sizes the smaller particles fit into and fill up the most of the pores between the larger particles.Or the soil which comprises of all particle sizes is called well-graded soil.; The poorly graded soils are the soils that consist of soil grains in a very narrow range of sizes. 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
