Abstract

A mixt. for prodn. of wood concrete screeds consists of a hydraulic binder and an aggregate mix of dedusted and impregnated wood flakes of pref. 4-8 mm. size, rigid foam material (e.g. styropor) in granulate or flake form, .and ceramic chips (pref. of brick, gas concrete, perlite, pumice, expanded clay or slag). ADVANTAGE - The mixt. exhibits reduced tendency for bubble and crack formation and has high wear resistance.

Description

Die Erfindung betrifft eine Estrichmischung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a screed mixture according to the preamble of claim 1.

Holzbetonestriche aus Holzspänen, gebunden mit diversen chemischen Mitteln, sind bekannt. Solche Estriche bilden häufig Blasen und weisen auch Risse auf. Die Widerstandsfähigkeit gegen Abrieb ist gering.Wood-concrete screeds made from wood chips, bound with various chemical agents, are known. Such screeds often form bubbles and also show cracks. The Resistance to abrasion is low.

Der Erfindung liegt die Aufgabe zugrunde, einen verbesserten Estrich zu schaffen, der gegenüber bekannten Estrichen in wesentlich geringerem Ausmaß zu Blasen- und Rißbildung neigt und eine erhöhte Widerstandsfähigkeit gegen Abrieb besitzt.The invention has for its object to provide an improved screed of bubbles to a much lesser extent than known screeds and tends to crack and has increased abrasion resistance.

Zur Lösung der gestellten Aufgabe dienen erfindungsgemäß die kennzeichnenden Merkmale des Anspruchs 1. Die Ansprüche 2 und 3 betreffen bevorzugte Weiterbildungen der erfindungsgemäßen Mischung.According to the invention, the characteristic ones serve to solve the stated problem Features of claim 1. Claims 2 and 3 relate to preferred further developments the mixture according to the invention.

Das erfindungsgemäße Produkt ist eine Estrichmischung, die nur eines üblichen, hydraulischen Bindemittels, wie etwa Zement oder Gips, bedarf.The product according to the invention is a screed mixture which only hydraulic binders, such as cement or gypsum, is required.

Die Estrichmischung besteht aus Holzflocken mit einer Flockengröße von bevorzugt 4 bis 8 mm, wobei es wesentlich ist, daß die Holzflocken entstaubt sind, um eine gute Bindung im fertigen Estrich zu erreichen. Weiter werden die Holzflocken gegen Feuchtigkeitsaufnahme imprägniert. Die Flocken werden mit Hartschaumstoff- Granulat oder -Flocken, z. B. Styropor, und Keramiksplittern (Mineralsplittern) in ausgewogener Dosierung vermengt, wobei es auf das Mengenverhältnis der einzelnen Bestandteile zueinander ankommt. Die Zuschlagmischung besteht aus zwei Raumteilen der vorgenannten Holzflocken, ein bis ein/einhalb Raumteile Hartschaumstoff- Granulat mit 3 bis 6 mm Korngröße sowie 1/6 bis 1/3 Raumteile Keramiksplitter einer Korngröße von 0 bis 5 mm. Diese Mischung gibt nach Zugabe des hydraulischen Bindemittels eine schaufelgerechte, streichfähige Masse, die ohne maschinelle Verdichtung, nach dem Trocknen, den gewünschten fußwarmen Estrich ergibt. Der Härtegrad des Estrichs ist außerdem durch Wahl der Menge der Keramikanteile regelbar. Die sorgfältige Entstaubung der Holzflocken ist notwendig, da es sonst bei nichtmaschineller Verdichtung zu unerwünschten Nestbildungen kommen würde. Die verarbeitungsmäßig günstigen Kleinteile in der Estrichmasse werden durch Beigabe der Keramiksplitter erreicht. Als Keramiksplitter werden vorzugsweise Ziegelsplitt, Gas-Beton-Grieß, Perlite, Bimsstein-Grieß, Schlacken-Granulat, Blähton u. ä. eingesetzt. All diese Materialien sowie auch die Holzflocken sind umweltfreundliche Produkte, die aus Recycling-Prozessen stammen.The screed mix consists of wooden flakes with a preferred flake size 4 to 8 mm, it being essential that the wood flakes are dedusted to to achieve a good bond in the finished screed. The wooden flakes continue impregnated against moisture absorption. The flakes are made with rigid foam Granules or flakes, e.g. B. Styrofoam, and ceramic chips (mineral chips) in balanced dosage blended, depending on the quantitative ratio of each Components come together. The aggregate mix consists of two room parts the aforementioned wood flakes, one to one and a half room parts rigid foam Granules with a grain size of 3 to 6 mm and 1/6 to 1/3 ceramic fragments one Grain size from 0 to 5 mm. This mixture gives after adding the hydraulic Binder is a scoop-compatible, spreadable mass that does not require mechanical compaction,  after drying, the desired warm floor screed results. The degree of hardness the screed can also be regulated by selecting the amount of ceramic content. Careful dedusting of the wood flakes is necessary, as it is otherwise with non-machine Densification would lead to undesirable nesting. The processing Favorable small parts in the screed mass are added by the Ceramic splinter reached. Bricks, gas-concrete semolina, Perlite, pumice stone semolina, slag granules, expanded clay and the like. Ä. used. All of these materials, as well as the wood flakes, are environmentally friendly products, that come from recycling processes.
