Porosity void ratio
WebJan 19, 2024 · Define the following terms: (i) water content (ii) void ratio (iii) porosity (iv) Unit weight of solids (v) Air content (vi) Bulk Unit weight (vii)Specific gravity. 0 0 SMDARJI Tuesday, January 19, 2024 (1) water content or Moisture content (w) WebThe void ratio is also an index of the fractional volume of soil pores, but it relates that volume to the volume of solids rather than to the total volume of soil. The advantage of this index over the previous one (f) is that a change in pore volume changes the numerator alone, whereas a change of pore volume in terms of the porosity will ...
