Structure and compressive behavior of Lightweight Clay Aggregate particle: experiments and numerical simulations

Lightweight Clay Aggregate (LWCA) is a kind of highly porous granular particle which often used as lightweight backfilling geomaterials. However, the easy breakage LWCA plays negative role in its geotechnical application. This study focuses on internal structure and compressive behavior single using experiments numerical simulations. The uniaxial strength loading stiffness attributed to special structure. results could enrich our understanding crushing.
