Description

Verfahren zur Herstellung von Glasuren auf Betongegenständen Die Erfindung betrifft eile Verfahren zur Herstellung von Betonmasse, die _ sich zum durchgreifenden Schutz gegen ZVitterungseinüüsse bzw. gegen die schädliche Einwirkung von Gasen, Säuren oder Salzlösungen usw. glasieren läßt.Process for the production of glazes on concrete objects The invention concerns an urgent process for the production of concrete mass, which _ is going to be penetrating Protection against weathering influences or the harmful effects of gases, Can glaze acids or salt solutions, etc.

Es ist bisher nicht gelungen, Glasuren in wirklich gut haftender und einwandfreier Ausführung auf Betonkörpern zu erzeugen. Versuche, den Beton mit Diner hasse zu bestreichen, die sich leicht glasieren läßt, scheiterten daran, daß eilte solche Glasur auf Beton nur stellenweise oder gar nicht haftet und leicht abspringt. Auch gelang es nicht, glasierte Platten auf Beton so dicht anzubringen, daß sie diesen erfolgreich schützen. Es ist ferner versucht worden, den Zement des abgebundenen Betons auf der Oberfläche zu entfernen und die freigelegten Zuschlagstoffe mittels einer Stichflamme zu schmelzen. Diese Glasur bindet sich jedoch mit dem in den Vertiefungen befindlichen Zement nicht und bildet keine homogene Deckschicht auf der Gesamtoberfläche des Betons, so daß auch ein solcher Schutz illusorisch wird. Es genügt aber auch nicht, die an sich schon witterungsbeständigen mineralischen Zuschläge bzw. Gesteine allein zu schmelzen, sondern die Hauptbedingung ist, das Bindemittel, also den Zement, widerstandsfähig zu gestalten. Den allgemein gebräuchlichen, abgebundenen Beton an der Oberfläche mit Hilfe einer Stichflamme oder auf andere Art zu glasieren, mißlingt aus dem Grunde, weil der gewöhnliche Zement einen Überschuß an ungebundenem Kalk aufweist, der zur Rißbildung neigt und nicht fließt.So far it has not been possible to make glazes in a really good adhesive and flawless execution on concrete bodies. Try the concrete with diner hate to coat, which is easy to glaze, failed because of the hurry Such glaze only partially or not at all adheres to concrete and easily pops off. It was also not possible to attach glazed plates to concrete so tightly that they protect it successfully. Attempts have also been made to cement the set Remove concrete on the surface and use the exposed aggregates to melt with a jet of flame. However, this glaze bonds with the one in the indentations existing cement and does not form a homogeneous surface layer on the entire surface of the concrete, so that such protection is also an illusion. But it is also sufficient not the already weather-resistant mineral aggregates or rocks to melt alone, but the main condition is that the binder, i.e. the cement, design resistant. The commonly used, hardened concrete to glaze on the surface with the help of a jet flame or in another way, fails for the reason that the ordinary cement has an excess of unbound Has lime, which tends to crack and does not flow.

Bei voller Würdigung aller Anforderungen an die Zusammensetzung eines einwandfreien Betons und bei Berücksichtigung der chemischen und physikalischen Schmelzvorgänge beim Glasieren schafft die Erfindung Abhilfe. Nach dem erfindungsgemäßen Verfahren wird eine Betonmasse hergestellt, die sich durch Erhitzung der Oberfläche mittels einer Stichflamilie mit einer vollkommen homogenen, rissefreien und gut haftenden Glasur bedecken läßt. Um dieses Ziel zu erreichen, werden verschiedene Wege gewiesen. -Vor allem sollen als Bindemittel für den an der Oberfläche anzuschmelzenden Beton Zemente mit geringem Kalkgehalt und niedrigerer Schmelztemperatur als Portlandzement, wie z. B. Eisenportlandzement, Verwendung finden. Hierbei gilt es, einen Ausgleich zu schaffen zwischen dem Schmelzpunkt des Zu- -sclllagstoffes iuid des Zements, um durch ein Ineinanderfließen der Teile einen homogenen Glasurüberzug zu gewinnen. Derartige Zuschlagstoffe sind Flußspat, Hochofenschlacke oder Klinker mit niedrigem Schmelzpunkt. Das vorwiegend kristallinische Gefüge ebenso wie die unter dem Einfluß der Hitze entstehenden Alumosilikate bedingen eilen verhältnismäßig niedrigen Schmelzpunkt der Zuschlagstoffe. Wird nun ein Zement mit niedrigem Schmelzpunkt gewählt, so kann ein gleichmäßiges Erweichen und Schipelzen der Betonoberfläche und dadurch die Bildung einer festhaftenden homogenen Glasur erreicht werden, trotzdem die Flamme wahllos Zement und Zuschlagstoffe trifft. Ferner kommt die Verwendung von Zementen von gleichen oder annähernd gleichen Schmelzpunkten wie denen der Zuschlagstoffe in Betracht, wobei die erwähnte Wirkung erzielt wird. Nicht beabsichtigt ist jedoch gemäß diesem Verfahren die Verwendung von Tonerdezement.With full appreciation of all the requirements for the composition of a flawless concrete and taking into account the chemical and physical The invention provides a remedy for melting processes during glazing. According to the invention Procedure, a concrete mass is produced, which is achieved by heating the surface by means of a stitch family with a completely homogeneous, crack-free and good one can cover adhering glaze. To achieve this goal, various Pointed the way. - Mainly intended as a binder for the to be melted on the surface Concrete cements with a low lime content and lower melting temperature than Portland cement, such as B. Eisenportlandzement find use. It is important to find a balance to create between the melting point of the additive iuid of the cement, in order to obtain a homogeneous glaze coating by flowing the parts into one another. Such additives are fluorspar, blast furnace slag or clinker with low Melting point. The predominantly crystalline structure as well as that under the influence The aluminosilicates produced by the heat have a relatively low melting point of the aggregates. If a cement with a low melting point is now selected, so can an even softening and peeling the concrete surface and thereby the formation of a firmly adhering homogeneous glaze can be achieved, nevertheless the flame hits cement and aggregates indiscriminately. Then comes the use of cements with the same or approximately the same melting points as those of the aggregates into consideration, whereby the mentioned effect is achieved. However, it is not intended according to this method the use of calcium aluminate cement.

Wird für die Zuschlagstoftkörner die Form von @i'ürfeici oder Pyramiden gewählt, so erhitzen sich diese Körper gleichmäßiger als solche schmaler, langgestreckter Form, so daß sieh eine Absplitterung vermeiden' und die Glasurbildung begünstigen läßt.The form of @ i'ürfeici or pyramids is used for the aggregate grains selected, these bodies heat up more evenly than those that are narrower, more elongated Shape so that you avoid chipping and promote glaze formation leaves.

Es besteht auch die Möglichkeit, leicht schmelzende müieralische Stoffe, wie Glas, Bimsstein o. dgl., in Pulverform in die Oberfläche einzubringen, z. B. unter Druck in die Betongegenstände einzuschleudern. Durch das Einschleudern von Glasstaub usw. in die Poren der Betonmasse wird die Einwirkung dieses die Schmelztemperatur erniedrigenden Ivlediums wesentlich erhöht, da bei einer feinen Verteilung der Stoffe die chemische Reaktion bei Einwirkung der Stichflamme an Intensivität zunimmt.There is also the possibility of using easily melting materials, Such as glass, pumice stone or the like. To be introduced into the surface in powder form, e.g. B. to be thrown into the concrete objects under pressure. By throwing in Glass dust etc. in the pores of the concrete mass is the action of this the melting temperature degrading Ivlediums significantly increased, since with a fine distribution of the substances the chemical reaction increases in intensity when exposed to the jet flame.

Sollen hierbei bestimmte Farbtöne erzielt werden, so können färbende Metalloxyde oder färbende Steine in die Poren der Betonoberfläche eingedrückt oder eingeschleudert werden.If certain shades of color are to be achieved here, coloring can be used Metal oxides or coloring stones pressed into the pores of the concrete surface or be thrown in.
