摘要

Fireproof element comprises an external cover strip (7) for tensioning a component; and a cover (6) partially enclosing an inner space containing a filling made from magnesium oxychloride cement or magnesium oxysulfate cement . An Independent claim is also included for a process for the production of a fireproof element. Preferred Features: The magnesium oxychloride cement has a composition MgCl2/Mg(OH)2/H2O with a molar ratio of 1: (2.5-5): (8-12) or the magnesium oxysulfate cement has a composition MgSO4/Mg(OH)2/H2O with a molar ratio of 1: (2.5-3.5): (6-10). The filling contains magnesium chloride and magnesium sulfate
