Traditional CT testing system, non real-time online scanning. The German Wille Rock Online Real time CT Triaxial Testing System enables simultaneous mechanical testing and CT scanning. X-ray transparent triaxial cell for low and high pressure tests.
Sample's porosity, crystalliza-tion and dissolution, exchange of pore fluids, pre and post-failure geometry, or even crack propagation can be now monitored in situ during testing, and also in a time-resolved manner.
Real time visualization of deformation of sample (consolidation, shear) and flow process (saturation, permeability) during test Two phase fluid flow (gas and liquid).
High potential for upgrades (visualization systems e.g. μ-CT, AE, ERT, custom made test jigs and environmental chambers etc.)
Usage: Natural gas hydrates, soil, rock, concrete, asphalt, synthetic building materials
CT online scanning allows researchers to obtain valuable images from internal structures to explore and verify the characteristics of various materials during stress processes, such as analyzing the relationship between pores, fluids, and materials during loading. Gain a deeper understanding of the uniformity, continuity, cracks, voids, and joints of the specimen.
