Description

Verfahren zur Herstellung feuersicherer Bauteile. Portlandzement erreicht in seiner Widerstandsfähigkeit gegen die Einwirkung von Hitze die untere Grenze der in der Technik als feuerfest bezeichneten Baustoffe, d. i. oberhalb etwa 155o°. Verarbeitet man ihn zu Beton, um daraus feuerbeständige oder feuersichere Bauteile herzustellen, so versagt er, wenn man ihm die üblichen Zuschlagstoffe aus Quarzsand, Kies, Silikatgestein-, Kalkstein-, Ziegelbruch u. dgl. zusetzt, weil entweder der Quarz mit seinen auch wenig haftfesten Flächen durch Wachsen unter .Hitzewirkung den Beton zermürbt, oder weil die sonst genannten Stoffe weit unter der Eigenschmelzung des Portlandzementes mit diesem zerfließen 1 Sogar feuerfeste Schamotte löst sich weit unter dem Schmelzpunkt des Zementes mit ihm in der Hitze im Fluß auf. Versuche mit sintergebrannten Magnesitbrocken, Korund und anderen ähnlichen teueren Zuschlagstoffen, die an sich widerstandsfähig genug sein würden, sind schon aus wirtschaftlichen Gründen aussichtslos.Process for the production of fire-safe components. Portland cement achieved the lower limit in its resistance to the action of heat the building materials referred to as refractory in technology, d. i. above about 155o °. If you process it into concrete, you can make fire-resistant or fire-safe components from it to produce, it fails if the usual aggregates made of quartz sand, Gravel, silicate stone, limestone, broken bricks and the like adds, because either the Quartz, with its surfaces that are also not very adhesive, is caused by waxing under the effect of heat the concrete wears down, or because the other substances mentioned are far below their own melting point of Portland cement dissolves with this 1 Even refractory chamotte dissolves far below the melting point of the cement with him in the heat in the river. try with sintered magnesite lumps, corundum and other similar expensive additives, which in themselves would be resilient enough are economic ones Reasons hopeless.

Überzieht man indessen gemahlene Brocken aus feuerfesten Tonen mit einer dünnen Schicht von korundähnlicher oder ähnlich wirkender Masse, die nachgewiesenermaßen j feuerfeste Schamottemassen vor der Einwirkung des Zementes vorzüglich schützen, .I so wird ein Beton mit solch zubereitetem Zuschlagstoff wenigstens die Widerstandsfähigkeit wie der reine Portlandzement gegen Schmelzung aufweisen, oder diese noch überschreiten, weil durch die Masseneinlagerung des unangreifbaren Zuschlagstoffes ein Eindringen der Hitze in den Beton bedeutend verzögert wird.In the meantime, ground lumps of refractory clays are coated with it a thin layer of corundum-like or similarly acting mass, which has been proven j excellent protection of refractory fireclay from the effects of cement, .I a concrete with such a prepared aggregate will at least have the resistance like pure Portland cement show against melting, or even exceed this, because due to the mass storage of the unassailable aggregate, penetration the heat in the concrete is significantly retarded.

Das zackige rauhe Schamottekorn gibt dem Beton außerdem die denkbar beste Festigkeit und erlaubt bei zweckmäßiger Körnung ein Heruntersetzen des Zementzusatzes gegenüber Zuschlagstoffen mit glatter, nicht saugender Fläche.The jagged, rough grain of fireclay also gives the concrete the conceivable best strength and, if the grain size is appropriate, allows the cement additive to be reduced compared to aggregates with a smooth, non-absorbent surface.

Die Verwendung eines derartigen Betons für alle Bauteile, die hohen Hitzegraden ausgesetzt werden können, ist ein billiger und sicherer Schutz gegen die zerstörende Wirkung des Feuers. Man braucht nur an die Tragweite des Verfahrens bei schwer belasteten Eisenbetonteilen, wie Unterzügen, Säulen u. dgl., zu denken, bei denen bei Brandgefahr z. B. Beton mit Kalksteinzuschlag schon bei recht niederen Hitzegraden unweigerlich der Zerstörung unterliegt, weil der Kalk gebrannt wird und unter Einwirkung des Löschwassers dann explosionsartig aufquillt. Ähnliche Beispiele lassen sich viele aufführen.The use of such a concrete for all components that are high Exposure to heat levels is a cheaper and safer way to protect against the destructive effects of fire. One only needs to consider the scope of the procedure to think about heavily loaded reinforced concrete parts, such as beams, columns, etc., where there is a risk of fire z. B. Concrete with limestone surcharge even with quite low Heat levels are inevitably subject to destruction because the lime is burned and then swells explosively under the action of the extinguishing water. Similar examples many can be listed.
