No-slump concrete (NSLC) and self-compacting concrete (SCC) are two types of concretes, which became increasingly adapted by the concrete industry because of their specific rheological characteristics. For NSLC mixtures the high shape holding ability allows formworks to be removed shortly after concrete placing. However, NSLC needs a large amount of energy to be properly compacted. For SCC mixtures it is the high flowability and self-compactability that makes them unique. However, as SCC is not able to preserve its shape right after placing, formwork cannot be removed directly after casting. By comparing these two extreme cases, an ideal mixture would have been obtained, i.e. a self-compacting no-slump concrete (SCNSLC), which can compact under its own weight and maintains its shape right after casting. in this paper the possibility of a self-compacting no-slump concrete (SCNSLC) is discussed. The rheological behaviour of these mixtures in the dormant period is in focus, when the degree of hydration is still very limited. The shape holding ability of both mixtures is characterized by a shape preservation factor 0
