Claims (1)

Patent-Anspruch:Patent claim: Ausführungsform des Verfahrens zur Verbesserung von. Aluminat und Silikat enthaltenden hydraulischen Bindemitteln, wie Hochofenschlacken und aus denselben hergestellten Zementen, Portlandzement u. dgl. durch Zusatz von Bariumsalzen. nach Patent 204699, dadurch gekennzeichnet, daß man den Bindemitteln vor oder nach dem Vermählen an Stelle von Bariumkarbonat eine den im Bindemittel und in dem als Anmachwasser verwendeten Meerwasser vorhandenen löslichen Sulfaten äquivalente Menge einer Verbindung zusetzt, deren Base ein unlösliches Sulfat bildet.Embodiment of the method for improving. Aluminate and silicate containing hydraulic binders, such as blast furnace slags and from the same manufactured cements, Portland cement and the like by adding barium salts. according to patent 204699, characterized in that the binders are added in place of barium carbonate before or after grinding one of the soluble sulfates present in the binder and in the seawater used as mixing water equivalent amount of a compound is added, the base of which forms an insoluble sulfate.
