Particle Breakage of Cement Ellipsoid Aggregate—Part I: Triaxial Compression Tests
Source abstract
Abstract
Abstract Cement ellipsoid aggregate was adopted to simulate rockfill materials in laboratory tests. The specimen was prepared by mixing cement ellipsoids of four diameters in a particular ratio. Triaxial compression tests and isotropic compression tests were then conducted to investigate the macroscopic stress–strain relationship of the aggregate, and the crushing characteristics of the cement ellipsoids. The particle size distributions were analyzed after testing. No particle breakage occurred during the isotropic compression tests or the unloading–reloading process of the triaxial compression tests; this implied that breakage of the cement ellipsoids mainly occurs during the shearing process of loading. Sieving analysis showed that the sizes of the larger particles did not change much; crushing mainly produced small particles and, thus, changed the particle size distribution.
