Nonstandard compression and creep of some (geo)materials are commented on. Such a behaviour results from some special features of soil structure and/or specific state parameters (density, water content etc.). The present study is based on laboratory tests showing some examples of nonstandard behaviour. This results mostly from the grain breakage and bonding-debonding mechanism. The study of the nonstandard behaviour is practically important because of showing the pitfalls of the routine approach.
