Abstract	This study extends previous work and demonstrates that magnetic resonance imaging (MRI) of water allows the internal crack pattern of hardened concrete to be observed along with the internal aggregate structure. The ability to reconstruct three-dimensional images is demonstrated and the importance of image registration is discussed. By using aramid fibre-reinforced plastics (AFRP), it is possible to make reinforced concrete specimens that can be measured by MRI. Plain concrete cylinders and others externally confined by AFRP spirals have been tested in compression and scanned after various amounts of load have been applied to show the progress of fracture development. Samples have also been made with straight AFRP rods cast into the concrete which, when pulled out, give bond failures and internal cracking. It is possible not only to observe the fractures, but also to relate them to the internal concrete structure determined by previous scans of the freshly prepared concrete samples.
