Web(0.075mm). GRAVEL (G) and SAND (S) are further identified or classified according to their gradation as well-graded (W) or poorly graded (P), SILT content (M), or CLAY content (C). Examples of these are Well-graded SAND (SW) or SILTY SAND (SM). Fine-grained soils pass more than 50 percent of material through the No. 200 sieve. SILT (M), The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain siz… fitso near me https://ethicalfork.com
