angle of repose silica sand
The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping At this angle, the material on the slope face is on the verge of sliding

The angle of repose, or critical angle of repose,  of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping At this angle, the material on the slope face is on the verge of sliding The angle of repose can range from 0° to 90° The morphology of the material affects the angle of repose; smooth .
Soil friction angle is a shear strength parameter of soils Its definition is derived from the Mohr-Coulomb failure criterion and it is used to describe the friction shear resistance of ,
Green sand consists of high-quality silica sand, about 10 percent bentonite clay (as the binder), 2 to 5 percent water and about 5 percent sea coal (a carbonaceous mold additive to improve casting finish)
