Reinforced concrete ceiling poured on site at the construction site. After erecting a formwork supported by yokes, the reinforcement, which essentially consists of steel meshes and steel rods, is inserted into the formwork with spacers. The concrete is delivered fresh to the construction site in the form of ready-mixed concrete or produced on site at large construction sites. It is inserted into the formwork by means of a concrete pump or sick bucket and compacted. In-situ concrete slabs require post-treatment after the concreting process. The ceiling may only be stripped after it has hardened sufficiently. In-situ concrete ceilings can be produced as flat ceilings, but also in other forms, e.g. as ribbed ceilings or coffered ceilings.
