Question

Value of angle of internal friction varies of soil is

Answer 1

Friable (moist) sandy loam soils are typically in the range 5 to 15 kN/m2 and moist plastic clay soils 10 to 40 kN/m2. Angle of Internal Friction (φ) Theoretically a pure clay would have a value of 0° and φ would rise with increasing sand content and density to approximately 40° for a compact sandy loam soil.
