Description
Herstellung von hydraulischen Bindemitteln oder sonstigem Baustoff. Bisher sind meist gekörnte Schlacken zur Herstellung von Bindemitteln verwendet worden. Die Erfindung bezweckt, das Körnen zu umgehen und Haldcngut an sich, so wie es sich in der Kohlenaufbereitung und aus der Verbrennung und aus den Eisenerzschmelzbetrieben (Basischer Hochofenbetrieb, Saurer Martinbetrieb) und der Eisenerzaufbereitung ergibt, unmittelbar als Ausgangserzeugnisse für die Herstellung von Bindemitteln und Bausteinen zu verwenden.Production of hydraulic binders or other building materials. So far, mostly granular slag has been used for the production of binders been. The aim of the invention is to circumvent the grain and woodland material per se, so as it is in coal preparation and from combustion and from iron ore smelters (Basic blast furnace operation, Saurer Martin operation) and the iron ore processing results, directly as raw materials for the production of binders and building blocks to use.
Die Erfindung beruht auf der Erkenntnis, daß der verschieden große Gehalt an Kalziumoxyd, Kieselsäure und anderen hydraulischen Bestandteilen in den vorgenannten Abfalistoffen bei geeigneter Vermischung derselben allein genügt, um ein Abbinden hervorzurufen, das gegebenenfalls bei gewünschtem größeren Abbindungsvermögen oder größerer Festigkeit durch Hinzufügen zusätzlicher Mengen von Kalziumoxyd erhöht werden kann.The invention is based on the knowledge that the different sizes Content of calcium oxide, silica and other hydraulic components in the The above-mentioned waste materials, if mixed appropriately, alone suffices to to cause a setting, possibly with the desired greater setting capacity or increased strength by adding additional amounts of calcium oxide can be.
Maßgebend für diese Erkenntnis war die Feststellung, daß sich in den vorgenannten Abfallstoffen, sei es zufolge Verarbeitung der Rohstoffe; sei es zufolge der Haldenlagerung und der hierbei auftretenden chemischen Vorgänge, hydraulisierende Bestandteile in verschiedener Menge bilden. Je nachdem nun das gewünschte Bindemittel oder der Baustein mehr oder weniger Abbindekraft oder Festigkeit haben soll, wird man sich mit der Vermengung der gemahlenen Haldenstoffe in bestimmten Verhältnissen mit oder o, ne Zusatz von Kalk oder Zement abfinden müssen.The decisive factor for this finding was the finding that in the the aforementioned waste materials, be it according to processing of raw materials; be it according to the dump storage and the chemical processes that occur here, hydraulic Form components in different amounts. Depending on the desired binding agent or the building block should have more or less setting power or strength you deal with the mixing of the ground stockpile materials in certain proportions with or without the addition of lime or cement.
So z. B. mischt man 25 Prozent Kalziumoxyd mit 75 Prozent von der Halde genommenem, d. h. auf der Halde natürlich gebranntem Kohlenschiefer (Opuka) und erhält ein Bindemittel, welches mit dem gleichfalls der Halde entnommenen Rösterzstaub innig vermengt, mit Wasser angemacht und in Formen gebracht einen Baustein von genügender Festigkeit ergibt. Mit Rösterzstaub ist das bkher als wertloser Abfall behandelte sandige, staubige und aussortierte Eisenerz aus den Röstprozessen gemeint, denen gewisse Eisenerze vor der Verhüttung unterzogen werden.So z. B. mix 25 percent calcium oxide with 75 percent of the Heap taken, d. H. Naturally burned coal shale (Opuka) on the heap and receives a binding agent which is mixed with the roasting dust that is also removed from the heap intimately mixed, mixed with water and shaped a building block of sufficient Gives strength. With roasting dust, what was previously treated as worthless waste sandy, dusty and discarded iron ore from the roasting processes meant them certain iron ores are subjected to before smelting.
Soll beispielsweise die vorgenannte bestimmte Schlacke zur Herstellung dieses Bin.iemittels oder Bausteines verwendet werden, so genügt bereits für gewisse Erfordernisse der Kalkgehalt der aus dem Basischen Hochofenbetrieb kommenden Haldenschlacke, um in Verbindung mit gewissen hydraulischen Stoffen des Kohlenschiefers wirksam abzubinden.For example, if the aforementioned specific slag is intended for production of this bin .ie means or module are used, it is already sufficient for certain Requirements of the lime content of the slag from the base blast furnace operation, to be effective in connection with certain hydraulic substances of the coal shale tie off.
Selbstverständlich werden bei den vorgenannten Beispielen bei der Herstellung von Bausteinen Füllmittel verwendet, die an und für sich hydraulische Eigenschaften haben, so daß sie die Bindekraft des Bindemittels verstärken. In Betracht kommen diesbezüglich kohlenschieferhaltige Aschen oder Rösterzstaub.Of course, in the aforementioned examples, the Manufacture of building blocks uses fillers that are hydraulic in and of themselves Have properties such that they enhance the binding force of the binder. Into consideration In this regard, there are ashes or roasting dust containing coal shale.
Als bekannt wird vorausgesetzt, Eisenerz und gekörnte Hochofenschlacke gemeinsam auf hydraulische Bindemittel zu verarbeiten, ferner Hochofenschlacke und Brennstoffasche zu einem Traßersatz zu vermahlen und schließlich Brennstoffaschen und Hochofenschlacke auf Bausteine zu verarbeiten.Iron ore and granular blast furnace slag are assumed to be known to be processed together on hydraulic binders, furthermore blast furnace slag and To grind fuel ash to a truss substitute and finally fuel ash and to process blast furnace slag on building blocks.
