2 is based on data for relatively clean sands, thus, sands with a significant amount of clay/silt-sized material will fall in the lower portion of the range. The reported values of effective friction angle (ϕ′), based on SPT N60 values, should be reduced by 5° for clayey sands and should be increased by 5° for gravelly sands.

What Is Sand Made Of?
Sand Is Made From Eroded Rock. A lot of the sand (both beach and desert) is made from eroded rock. As rivers flow downstream from their origin, their movement (often violent) erodes rocks down to very small grains of minerals and carries these small portions of rock along with it as it travels. Along the river's journey, the pebbles continue ...
