A series of triaxial compression tests was performed on three types of granulated coal ash (GCA) to investigate their shear and crushing behaviour. The experimental results show that GCA displays different dilatancy characteristics to other natural granular materials due to excessive breakage even at low stresses. A simple constitutive model for crushable soils with …
