Fire resistance body and method for manufacturing the same

The invention relates to a fire resistance body and a manufacturing method for fire resistance body. The fire resistance body has a fire resistance of at least F30 and the fire resistance body has a first zone (6) and a second zone (7), wherein the first zone and the second zone with respect to at least one parameter selected from the following list differ from each other : density, median diameter of the macropores of the macropores, distribution width of the pore size distribution of the macropores, chemical composition. The process for preparing a fire resistance body comprises preparing a first composition comprising a first water-gypsum dispersion, forming a first wet foam by foaming the first composition, forming a second wet foam by foaming the first composition or a second composition, wherein the first and the second wet foam from one another differ with respect to at least one selected from the group consisting of the composition, conditions during foaming, in particular the intensity of foaming, the setting of the first and second wet foam, wherein the first wet foam has a first zone (6) the fire resistance body forms and the second wet foam a second zone (7) of fire resistance body forms, with the first zone and the second zone with respect to at least one parameter selected from the following list different from each other: density, median diameter of Makroporen, spreading width of Porengrossenverteilung of Makroporen, chemical composition and drying the Feuerwiderstandskorpers, wherein the first zone and the second zone of the Feuerwiderstandskorpers stoffschlussig interconnected are.
