  • the flowable mass is filled into an oiled casting mold which can be moved on rails and has a volume of between 4 and 9 m 3 .
  • the casting mold After the casting mold has been filled, it is brought to a fermentation station, where the mass is fermented to its final volume and remains between one and six hours until the binder component has set enough green strength for the sawing.
  • the filled mold is then conveyed to a sawing station and released and then the mass is cut in a sawing station by means of wires.
  • the cut material on trolleys is either driven directly into an autoclave or collected on stands in front of autoclaves until there is an autoclave filling and then pushed into an autoclave.
  • autoclaving which is usually about 12 hours, the material is removed from the autoclave, unloaded in an unloading device, packaged and transported to the warehouse.
  • a casting station 101 the cleaned and oiled Molds filled with an aerated concrete mixture and then on Proofing stations 102 move where the mass floats in the molds sets.
