IDENTIFICATION OF CEMENTATION IN OVERCONSOLIDATION CLAYS

The note describes the application of the generalized compressibility equations for normally and overconsolidated clays (presented by Nagraj & Srinivasa Murthy, 1986) based on physico-chemical principles. The ideas are used in a new combination as a method of identifying possible particle cementation in overconsolidation clays. Examination of the present method indicates that errors due to cementation of overconsolidated soils are likely. The note recommends the inclusion of a step which compares the shear strength of the soil sample to that predicted for that soil based on physico-chemical principles. The derived sensitivity can be used to avoid cemented soils being inadvertently analyzed as uncemented overconsolidated soils.
