OPTIMUM COMPACTION WET & DRY - civil engineering vk

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
