Small-strain behaviour of cemented soils

The shear modulus of cemented soils at very small strain (G0) was studied. For artificially cemented clay, G0 was found to be independent of the mean effective stress until the yield stress. After yield, a significant effect of structure degradation on G0 was observed. The experimental data were interpreted by an equation, which relates G0 of cemented soils to mean stress, apparent overconsolidation ratio and the state of structure (sensitivity). The equation was also found to represent G0 of cemented sands.
