Description

Verfahren zur Herstellung eines hydraulischen Bindemittels. Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Gewinnung eines hydraulischen Bindemittels unter Verwendung von Ölschieferschlacke.Process for the production of a hydraulic binder. The present The invention relates to a method for obtaining a hydraulic binder using oil shale slag.

Wegen ihres hohen Gehaltes an Schwefelverbindungen ließen bisher sehr viele Öl-Schieferschlacken eine Verarbeitung auf raumbeständige hydraulischeBindemittel nicht oder allenfalls nur unter sehr schwierigen und umständlichen Voraussetzungen zu. Gemäß der vorliegenden Erfindung ist dies nun in einfacher Weise dadurch möglich, daß die zu verarbeitende ölschieferschlacke unter einem Zuschlag von etwa 15 Prozent Portlandzement etwa zur Hälfte mit staubfein gemahlener basischer wassergekörnter Hochofenschlacke vermischt wird. Auf diese Weise ergibt sich selbst aus einer Ölschieferschlacke iriit verhältnismäßig hohem Gehalt an Schwefelsäureanhydrid ein raumbeständiges hydraulisches Bindemittel von hoher Festigkeit, wobei für viele Zwecke schon ein geringerer Zementzusatz genügt.Because of their high content of sulfur compounds, they have so far left a lot Many oil slate slag is processed on volumetric hydraulic binders not or at most only under very difficult and cumbersome conditions to. According to the present invention, this is now possible in a simple manner by that the oil shale slag to be processed under an addition of about 15 percent Portland cement about half with powder-fine ground basic water-grained Blast furnace slag is mixed. In this way it results from an oil slate slag itself With a relatively high content of sulfuric anhydride it is a stable one hydraulic binder of high strength, being already a for many purposes less cement is sufficient.

'Um den Gehalt des zuzuschlagenden Port-Landzementes an Sch`vefelsäureanhydrid möglichst gering zu halten, kann dieser in Form von Klinkern verwendet werden, denen der übliche Gipszusatz fehlt, wobei die Vermischung sämtlicher Stoffe am zweckmäßigsten durch gemeinsame Vermahlung erfolgt. Die besten Ergebnisse erzielt man unter Verwendung hochkalkiger schwefelarmer Portlandzemente.'' To determine the amount of sheepleic anhydride in the port land cement to be added To keep this as low as possible, this can be used in the form of clinker, which the usual gypsum additive is missing, whereby the mixing of all substances is most expedient takes place by joint grinding. The best results are achieved using high-lime, low-sulfur portland cements.
