3D tomography characterisation of porous graphite and calcium sulphate with controlled porosity

Scientific Case

As part of the research for the project of QUBE: QUasi-Brittle fracture: a 3D Experimentally-validated approach. Two type of specimens porous graphite with 50% macro-porosity and hydrated calcium sulphate with controlled porosity (0%, 10% and 20%) have to be characterised by 3D tomography. Combined with high-resolution re-construction using focus ion beam milling at the University of Bristol, the bi-modal distribution of the pores can be quantified. This can provide 3D pore structure as input to the models at Manchester University and Oxford University.
