Organic soil density
Witryna1 sty 2024 · The average bulk density of fibrous peat is around the unit weight of water (9.81 kN/m3). For organic soils with an organic content of 75% and greater, the specific gravity is in the range from 1.3 to 1.8 with an average of 1.5. The natural void ratio commonly ranges from 5 to 15 and it is around 25 for fibrous peat.
