Optimum Compaction Wet and dry
Dry of Optimum Compaction and Wet of Optimum compaction
Comparing between and dry and wet of optimum compaction
Properties changes with compaction | Dry optimum | Wet of Optimum |
Structure after compaction | Flocculated (Random) | Dispersed (Oriented) |
Water deficiency | More | Less |
Permeability | More, Isotropic | Less, Isotropic |
Compressibility | ||
at low stress | Low | Higher |
at high stress | High | Lower |
Swelleability | High | Low |
Shrinkage | Low | High |
Stress strain Behavior | Brittle,high peak, Higher elastic modulus | Ductile, No peak, Lower elastic modulus. |
Strength (undrained) as mould after saturation | High | Much lower |
Construction Pore Water Pressure | Low | High |
