Abstract
Foamed cements have the advantage of low density and good thermal isolation properties. In an effort to improve their low mechanical properties, a detailed study of the failure mechanism of foamed cement is undertaken. By means of in-situ micro compression tests inside an X-ray scanner, deformation and fracture of small specimen can be observed in detail.
Using a simple beam lattice model, the material is modelled and fracture is simulated, taking into account as much as possible detail of the material structure. Direct 3D comparison with the outcome of the experiments is possible which is further assisted by using directly the material structures measured on the small samples that are subsequently tested in the X-ray scanner. Some preliminary test results and simulations are presented in this paper.
