Beschreibung
Zusammenfassung:	The invention relates to fireproof, sprayable compounds, or fireproof, unfired mouldings, containing, as the main fireproof component, sintered magnesite, sintered dolomite, or a mixture thereof, together with 0.5 to 5% by weight of bentonite, 1 to 5% by weight of aluminium sulphate, and 0.5 to 5% by weight of an alkaline earth compound comprising caustic calcined magnesite, magnesium hydroxide or a mixture thereof. The compounds or mouldings according to the invention have the advantage that they do not suffer from bondingagent migration and that no devaporization cracking or flaking occurs.
