Infilled fracture: If the infilling is a weak clay or fault gouge, the friction angle (Cl) is likely to be low, but there may be some cohesion if the infilling is undisturbed. Alternatively, if the infilling is a strong calcite, for example, which produces a healed surface, the cohesive strength may be significant (see Section 2.3). 2. slow steam download speed windows 11

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.
