The present disclosure provides an apparatus for characterizing mechanical properties of a sample. The apparatus comprises a structure for supporting the sample and applying a first pressure in a first direction to the sample and an actuator for modulating the first pressure. The apparatus also comprises a pressure applicator containing a liquid and arranged to apply a second pressure to the sample in a second direction that is transversal to the first direction. Further, the apparatus comprises a pore pressure applicator arranged to apply a flow of a fluid through a porous sample such that a pore pressure is applied to the porous sample. In addition, the apparatus comprises a sensor for sensing a change in the sample in response to a change in a pressure experienced by the sample.

Apparatus for and a method of characterising mechanical properties of a sample

A method for determining the density of cement slurry in undersea drilling is disclosed. The method uses the reflection of acoustic waves from the slurry in order to determine its acoustic impedance and thus its density.
