A concrete floor assembly is disclosed including a subfloor element with a floor side and a ground/ceiling side, and a top casting layer. In at least one embodiment, the subfloor element includes a concrete portion on the floor side, which concrete portion has a bottom casting surface with a surface roughness. The top casting layer includes a casting composition, which includes a self-compacting concrete and a shrinkage reducing admixture. The top casting layer is cast on the floor side of the subfloor element so that at least a portion of the bottom casting surface is covered by the top casting layer, the bottom casting surface having such surface roughness that the top casting layer adheres to the bottom casting surface. A method of providing such a concrete floor assembly is also disclosed, as well as a floor assembly. |
