WebHere are some key points about sandstone: Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. Sandstone can be classified based on composition (e.g. quartz arenite, … WebSand typically has negligible shear strength at zero confining stress and is generally modeled with a cohesion value of zero. The phi value is typically estimated based on … WebFeb 5, 2024 · Before 400 °C, the water inside the sandstone gradually evaporated, which weakened the cohesion of the sandstone. Meanwhile, the lubrication between the particles was reduced, and the friction between the mineral particles gradually increased, leading to an increase in the internal friction angle. However, at temperatures greater than 400 °C ... i got the magic in me b.o.b
