Abstract

The surface of concrete blocks is improved by the flame spray application of a silicate melt layer which forms a glaze on the relevant surface. In the prefd. method the surface is preheated by playing a gun flame over the surface to be sprayed. The process is cheap and simple and permits the coating of types of concrete which would not otherwise be coated, since they do not stand up to furnace heating.

Description

Verfahren zur Veredelung der Oberfläche von Betonkörp ern Die Erfindung betrifft ein Verfahren zur Veredelung der Oberfläche von Betonkörpern. Process for finishing the surface of concrete bodies The invention relates to a process for finishing the surface of concrete bodies.

Der Verwendung von Betonkörpern anstelle der verhältnismäßig teuren gebrannten keramischen Körper sind in vielen Fällen Grenzen gesetzt, da das monotone Aussehen der Oberfläche eines Betonkörpers den Anforderungen oft nicht entspricht, in anderen Fällen auch deshalb, weil die Oberfläche eines Betonkörpers leicht verschmutzt und nicht säure- und abriebfest genug ist. Es hat nicht an Vorschlägen gefehlt, das Aussehen einer Betonoberfläche ansehnlicher zu machen, wie z.B.The use of concrete bodies instead of the relatively expensive ones Fired ceramic bodies are in many cases limited, as this is monotonous The appearance of the surface of a concrete body often does not meet the requirements, in other cases also because the surface of a concrete body is slightly soiled and is not acid and abrasion resistant enough. There was no shortage of suggestions make the appearance of a concrete surface more attractive, such as

durch Anwendung eines sogenannten Sichtbetons, aber eiinewirklich befriedigende Lösung läßt sich auch auf diese Weise niht erreichen, vor allem auch nicht eine säure- und abriebfeste Oberfläche.by using a so-called exposed concrete, but really a satisfactory solution cannot be achieved in this way, above all not an acid and abrasion resistant surface.

Um eine befriedigende Oberfläche eines Betonkörpers zu erhalten, die der der üblichen keramischen Körper gleichwertig ist, wird erfindungsgemäß so verfahren, daß auf die zu veredelnde Oberfläche mit Hilfe des Flammspritzverfahrens eine eine Glasur bildende Silikatschmelze aufgebracht wird. Man erhält auf diese Weise eine glasierte Oberfläche, die säure- und abriebfest ist und der farbmäßig das Aussehen gebrannter und glasierter Körper gegeben werden kann.In order to obtain a satisfactory surface of a concrete body, the which is equivalent to the usual ceramic body, the procedure according to the invention is as follows: that on the surface to be refined with the help of the flame spraying process a Glaze-forming silicate melt is applied. This is how you get a glazed surface that is acid- and abrasion-resistant and the color-wise the appearance fired and glazed bodies can be given.

Während es nicht möglich ist, Betonkörper in der für keramische Körper üblichen Weise zu glasieren, d.h. auf den Betonkörper eine eine Glasur bildende Masse aufzubringen und den Betonkörper zusammen mit dieser Masse zu brennen, weil der Betonkörper den bei den erforderlichen Temperaturen entstehenden inneren Spannungen nicht gewachsen ist, läßt sich mit Hilfe des Flammspritzverfahrens auf diesen eine Glasur aufbringen, ohne daßder Betonkörper selbst hohe Temperaturen anzunehmen braucht. Die beim Aufbringen der Silikatschmelze eintretende Erwärmung des Betonkörpers beschränkt sich im wesentlichen auf seine Oberfläche.While it is not possible to have concrete bodies in the for ceramic bodies usual way to glaze, i.e. a glaze on the concrete body Apply mass and burn the concrete body together with this mass, because the concrete body to the internal stresses arising at the required temperatures has not grown, can be applied to this one with the help of the flame spraying process Apply glaze without the concrete body itself needing to accept high temperatures. The heating of the concrete body that occurs when the silicate melt is applied is limited essentially on its surface.

Das Aufbringen der Glasur geschieht mit an sich bekannten Flammspritzpistolen, die mit einem Behälter zur Aufnahme des aufzubringenden Pulvers ausgerüstet sind. Wesentlich im vorliegenden Fall ist, daß nicht ein Gemisch aus den glasurbildenden Bestandteilen aufgebracht wird, sondern daß zunächst die betreffende Pulvermischung geschmolzen, d.h. eine Silikatschmelze, hergestellt wird, diese Schmelze nach ihrem Erstarren zu Pulver zerkleinert und dieses Pulver mit Hilfe der Flamme auf die Betonoberfläche aufgebracht wird. Auf diese Weise ist sichergestellt, daß nicht einzelne geschmolzene Komponenten des Pulvers, sondern eine wirkliche Glasur auf die Betonoberfläche aufgebracht werden.The glaze is applied with flame spray guns known per se, which are equipped with a container to hold the powder to be applied. It is essential in the present case that not a mixture of the glaze-forming Components is applied, but that first the person in question Melted powder mixture, i.e. a silicate melt, is produced, this melt after it has solidified to powder and this powder with the help of the flame is applied to the concrete surface. This ensures that not individual melted components of the powder, but an actual glaze be applied to the concrete surface.

Um eine gleichmäßige Glasur zu erreichen ist weiter wichtig, daß die Körnung der zerkleinerten Schmelze gleichmäßig ist.In order to achieve a uniform glaze, it is also important that the The grain size of the crushed melt is uniform.

Die Abmessungen der Körner soll möglichst gleich sein, beispielsweise 0,1 bis 0,2 mm betragen, d.h. die erstarrte und pulverisierte Silikatschmelze soll entsprechend ausgesiebt werden.The dimensions of the grains should be the same as possible, for example 0.1 to 0.2 mm, i.e. the solidified and pulverized silicate melt should be are screened out accordingly.

Beim Aufbringen der Silikatschmelze auf die Betonoberfläche soll diese zweckmäßig vorerwärmt sein, vorzugsweise auf ca.When the silicate melt is applied to the concrete surface, it should suitably preheated, preferably to approx.

1500C, Dies kann in der Weise geschehen, daß der Flamme der Spritzpistole eine nur zur Aufheizung dienende Flamme vorgeschaltet wird. Das Erwärmen der Oberfläche benötigt nur eine kurze Zeit.1500C, this can be done in such a way that the flame of the spray gun a flame that is only used for heating is connected upstream. The warming of the surface only takes a short time.

Für das Aufbringen der Silikatschmelze hat sich weiter als günstig erwiesen, wenn die Oberfläche des Betonkörpers vor dem Aufbringen der Silikatschmelze durch eine verdünnte Wasserglaslösung verfestigt wird.For the application of the silicate melt has further proven to be favorable proven when the surface of the concrete body before the application of the silicate melt is solidified by a dilute water glass solution.

Die Erfindung ist anwendbar auf Betonkörper beliebiger Art, vorzugsweise auf vorgefertigte Betonkörper. Die Erfindung gestattet beispielsweise die Herstellung von Fassadenplatten aus Beton, die zur Verkleidung von Außen- oder Innenwänden verwendet werden können.The invention is applicable to concrete bodies of any kind, preferably on prefabricated concrete bodies. The invention permits manufacture, for example of facade panels made of concrete, which are used for cladding external or internal walls can be.
