EK521
When an assembly of particles in a very loose packing is being loaded by shear stresses, there will be a tendency for volume decrease. This is called contractancy.
EK520
Dilatancy is the increase in volume that may occur during shear.
EK511
Undrained shear strength is the shear strength of a soil when sheared at constant volume.
EK495
Secondary compression is the change in volume of a fine-grained soil caused by the adjustment of the soil internal structure after primary consolidation has been completed.
EK494
Primary consolidation is the change in volume of a fine-grained soil caused by the expulsion of water from the voids and the transfer of stress from the excess porewater pressure […]
EK439
Shrinkage for concrete is the volume reduction with time.
EK247
The change in the volume of drying concrete is not equal to the volume of water removed. The evaporation of free water causes little or no shrinkage. As concrete continues […]
