The triaxial cell was then put inside the magnetic core for Magnetic Resonance Imaging (MRI). The MRI at New Mexico Resonance have a resolution of one part in 512 which is 0.1 mm for a 5-cm specimen making it suitable to study the void distribution. We captured the image of the voids (filled with water) between solid particles. Measurements yield the initial packing of the specimens. Uniformity of the samples can be detected. This study has demonstrated the feasibility of using MRI to study the void distribution of sand specimens.
