The objective of the work will be to provide experimental data on the evolution (degradation) of cementation of artificially and naturally cemented geomaterials.
This project will extend work performed in a recently completed PhD thesis. This will be achieved by monitoring the shear wave velocity as the materials are subjected to a range of stress paths. The rationale behind this approach is that the shear wave velocity is sensitive to the amount of cementation and provides a non-destructive measurement. The experimental data will allow an evaluation of the different strategies employed in constitutive models to reproduce the effects of cement degradation.
