- Mimicking the pressure changes in groundwater during earthquakes. Changes in groundwater pressure can trigger precipitation and dissolution of minerals, changing water chemistry and fracture surfaces. This in turn can lead to changes in rock friction, potentially increasing the magnitude of future earthquakes.

Abstract of funded proposal:
In the proposed experiments we aim to develop the scientific case to underpin the use of novel colloidal silica based grouts for radioactive waste containment. We aim to use the element specific capabilities of synchrotron based X-ray CT at beamline I13-2 to investigate the effects of the grout injection on the geochemistry of Sr, Cs and U. We will also utilize the time resolved capabilities to determine the influence of complex solid matrices on the (injection) behaviour of the silica grouts.
