Particle size distribution and relative breakage for a cement ellipsoid aggregate

Following the completion of triaxial compression tests on cement ellipsoid specimens, the particle size distribution for the specimen was analyzed after testing. It is found that neither particle strength nor confining pressure had much effect on the particle size distribution of completely broken particles. That is, the aggregates with different particle strengths have approximately the same fractal dimension. Hardin’s relative breakage was modified based on the concept of optimum distribution. Also, a relationship between relative breakage and plastic work was suggested and verified in this paper.
