That consolidation is 1. the binding of grains by cementing material to solid matrix [16]. 2. the gradual reduction in the water content (void ratio) of a saturated soil, as a result of an increase in the pressure acting on it, because of the addition of overlying sediments or the application of an external load. a laboratory test commonly known as a one-dimensional consolidation test (odometric test), is performed consolidation, cv usually expressed in cm2/sec, is calculated as the ratio where k is the hydraulic conductivity, on soil samples to evaluate consolidation. from such a test, the coefficient of mv is the coefficient of volume compressibility, and ?w is the unit weight of water. the theory of consolidation leads to a relation between degree of consolidation and time: in this expression u is the degree of consolidation or the percentage of total consolidation occurring in some time t; cv is the coefficient of consolidation; and h is half of the sample's thickness when the odometric test is performed [21].?
