Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von schwer entflammbarem Leichtbeton unter Verwendung bestimmter Zuschlag stoffe zur weiteren Herstellung entsprechender Leichtbeton- Bausteine.The invention relates to a method for producing heavy flammable lightweight concrete using certain surcharge materials for the further production of corresponding lightweight concrete Building blocks.
Als Zuschlagstoffe werden hierbei in besonderer Weise aufberei tete Abfallprodukte, insbesondere Gasbetonbruch und Hochofen schlacke wiederverwendet und unter Zugabe von Portlandzement, Sand und Wasser zu aushärtbarem Leichtbeton verarbeitet.The aggregates are processed in a special way Waste products, especially gas concrete breakage and blast furnace slag reused and with the addition of Portland cement, Sand and water processed to hardenable lightweight concrete.
Nach dem allgemeinen Stand der Technik werden zur Herstellung von Leichtbeton die verschiedensten Zuschlagstoffe eingesetzt. Hierzu zählen vor allem Schlacken, Asche, Gasbetonbruch und Gips. Je nach den zu erreichenden Eigenschaften des Leichtbetons wer den die Zuschlagstoffe mit Portlandzement, Sand und Wasser in einem entsprechenden Mischer aufbereitet. Homogenität und Härte des ausgehärteten Leichtbetons sind unterschiedlich, was einen qualitätsmindernden Effekt darstellt und auf unausgewogene Misch ungsverhältnisse zurückzuführen ist.According to the general state of the art are used to manufacture various aggregates are used by lightweight concrete. Above all, this includes slag, ash, gas concrete breakage and gypsum. Depending on the properties of the lightweight concrete to be achieved which the aggregates with Portland cement, sand and water in processed in an appropriate mixer. Homogeneity and hardness of the hardened lightweight concrete are different, which one represents quality-reducing effect and on unbalanced mix conditions.
Bei anderen Verfahren, bei denen ebenfalls Gasbetonbruch als Zuschlagstoff verwendet wird, wird dieser auf eine mittlere Korngröße von etwa 15 mm gebrochen und bis zur Sättigung in Wasser durchnäßt und anschließend in bekannter Weise mit Port landzement, Sand und Wasser gemischt, wobei die verschiedensten Mengenverhältnisse angewendet werden. In other processes in which gas concrete fracture is also considered If aggregate is used, this will be on a medium Grain size of about 15 mm broken and until saturated in Soaked water and then in a known manner with port land cement, sand and water mixed, the most varied Ratios are applied.
Diese Verfahren haben den Nachteil, daß die aus dieser Leicht betonmischung geformten Bausteine eine über längere Zeit anhal tende Restfeuchte aufweisen, weil der Gasbetonbruch das aufge saugte Wasser nicht spontan freigibt.These methods have the disadvantage that they are easy to use building blocks shaped for a long time tend residual moisture because the gas concrete break up sucked water does not release spontaneously.
Der Erfindung liegt die Aufgabe zugrunde, einen Leichtbeton zu schaffen, dessen Homogenität und Härte innerhalb eines Volumens, z. B. eines geformten Steines, konstant ist und darüber hinaus schwer entflammbar ist.The invention has for its object to a lightweight concrete create, its homogeneity and hardness within a volume, e.g. B. a shaped stone, is constant and beyond is flame retardant.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Gasbe tonbruch zerkleinert und durch Klassieren auf eine Korngröße von 10 bis 15 mm gebracht und während des Klassierens unter Ein wirkung von Saugluft entstaubt wird. This object is achieved in that Gasbe broken clay and by classification to a grain size brought from 10 to 15 mm and under classification during classification effect of suction air is dedusted.
Anschließend wird der klassierte Gasbetonbruch z. B. in eine Trommel mit entsprechender Lochung eingebracht und durch Ein tauchen in einen Behälter, der mit Natriumsilikat gefüllt ist, mit diesem benetzt.Then the classified gas concrete fracture z. B. in a Drum with appropriate perforation introduced and by on immerse in a container filled with sodium silicate, wetted with this.
Der benetzte Gasbetonbruch wird anschließend getrocknet und da nach mit der auf eine Korngröße von 5 bis 10 mm gebrachten Hochofenschlacke und Sand in einem Mischer unter Zugabe von Portlandzement und Wasser gemischt.The wetted gas concrete break is then dried and there after with the brought to a grain size of 5 to 10 mm Blast furnace slag and sand in a mixer with the addition of Portland cement and water mixed.
Nach der Erfindung wird der mit Natriumsilikat benetzte Gasbe tonbruch aus der Trommel auf ein endlos laufendes Band gebracht. Unter gleichzeitigem Rütteln des laufenden Bandes während des Durchlaufes durch einen Warmluftunnel erfolgt das Trocknen des Gasbetonbruches.According to the invention, the gasbe wetted with sodium silicate Broken clay brought out of the drum on an endless belt. With simultaneous shaking of the running belt during the Passing through a warm air tunnel, the Gas concrete break.
Um eine gleichmäßige Homogenität und eine gewisse Feuerfestig keit des Leichtbetons zu erreichen, werden je 1,5 Volumenteile Gasbetonbruch und Hochofenschlacke und je 0,5 Volumenteile Sand, Portlandzement und Wasser miteinander gemischt.For a uniform homogeneity and a certain refractory to achieve light concrete, 1.5 parts by volume each Gas concrete breakage and blast furnace slag and 0.5 volume parts of sand each, Portland cement and water mixed together.
Aus der nach der Erfindung hergestellten Leichtbetonmischung lassen sich in bekannter Weise Steine formen. Natriumsilikat ist unter anderem als Flammschutzmittel bekannt. Dadurch ist der Gasbetonbruch in Verbindung mit Hochofenschlacke, die so gut wie feuerfest ist, ebenfalls gegen Flammeinwirkung geschützt.From the lightweight concrete mixture produced according to the invention stones can be formed in a known manner. Sodium silicate is known, among other things, as a flame retardant. This is the Gas concrete breakage in connection with blast furnace slag, which is so good how fireproof is, is also protected against exposure to flame.
