Criteria that govern the failure mechanisms, variability and strength of rubble masonry concrete (RMC) are explored with reference to the behaviour of analogous particulate composites. Contiguous particle interaction and the potential for anisotropy are noted as two distinguishing characteristics that may account for much of this material's unique behaviour. Failure appeared to be initiated by deboning of the stone-mortar interface parallel to the principal stress long before the specimens attained their maximum stress. Variability of mechanical properties was found to be a function of anisotropy and heterogeneity.
