Modelling of cementation bonds in clay – laboratory and numerical model

Abstract

Artificial cementation bonds were created in a model clayey material by adding 4 of Portland cement to kaolin clay. The mechanical behaviour of the model material was compared with the behaviour of the pure reconstituted kaolin clay.

Submersible LVDT´s and bender elements were used in identifying the elastic stiffness and the destructuration of the specimens.
