Abstract
Description
Die Erfindung betrifft einen Leichtbetonbaustein unter Verwendung von Polystyrol oder dgl., wie sie zur Her stellung von Gebäuden im Wohnungs- und Gesellschaftsbau in allen Größen eingesetzt werden.The invention relates to a lightweight concrete block under Use of polystyrene or the like provision of buildings in residential and social buildings can be used in all sizes.
Bekannt sind Bausteine aus den Bindemitteln Zement und Kalk und dem Zuschlagstoff Sand.Building blocks made of cement and Lime and the aggregate sand.
Derartige Bausteine sind in der Regel zu schwer und be sitzen eine zu geringe Wärmedämmung und kommen daher so kaum zur Anwendung.Such building blocks are usually too heavy and be Insulation is too low and therefore come like this hardly used.
Zur Verbesserung oder Vermeidung dieser Nachteile ist es bekannt, weitere Zuschlagstoffe wie textile Fasern, Holz- und Kunststoffteilchen in den unterschiedlichsten Zusammensetzungen zu verwenden. In letzter Zeit werden verstärkte Bemühungen deutlich, als Porenbildner Kunst stoffteilchen aus Polystyrol in den Formen von Granula ten oder durch Vergasung gerundete und geglättete Kügel chen zuzusetzen.It is to improve or avoid these disadvantages known, other additives such as textile fibers, Wood and plastic particles in a wide variety To use compositions. Lately be intensified efforts significantly as a pore builder art Polystyrene fabric particles in the shape of granules or rounded and smoothed by gasification to add.
So wird in der DE-G 92 01 498.4 ein Leichtzuschlagstoff in Form von zerkleinerten Polystyrol-Partikeln mit zerfa serter, rauher Oberfläche zugegeben. DE-G 92 01 498.4 is a light aggregate in the form of shredded polystyrene particles with zerfa Serter, rough surface added.
Desweiteren wird in der DE 40 34 721 zur Gewichtsredu zierung aus Altpolystyrol zerkleinertes Polystyrolgranu lat mit verschiedenen Korngrößen für verschiedene Anwen dungsfälle eingesetzt.Furthermore, in DE 40 34 721 for weight loss Decoration made from shredded polystyrene granules lat with different grain sizes for different applications use cases.
Der wesentliche Vorteil des Einsatzes von Polystyrol oder Styropor oder dgl. besteht in einer erheblichen Ge wichtsminderung und einer hohen Wärmedämmung der Beton elemente.The main advantage of using polystyrene or styrofoam or the like. consists in a considerable Ge weight reduction and high thermal insulation of the concrete elements.
Alle genannten Lösungen haben gemeinsam, daß das Poly styrol neben weiteren Zuschlagstoffen eingesetzt wird. Der Erhöhung des Anteils von Polystyrolteilchen sind da her Grenzen gesetzt, weil das zu Lasten der Anteile der anderen Zuschlagstoffe geht. Das beeinträchtigt irgend wann die Bindefähigkeit des Zementes, weil die Räume zwischen den Polystyrolteilchen immer größer werden und nicht mehr ausreichend gefüllt und die obendrein oft glatten Oberflächen der Polystyrolteilchen daher nicht mehr zur Genüge mit Zement umschlossen werden.All of the solutions mentioned have in common that the poly styrene is used in addition to other additives. The increase in the proportion of polystyrene particles are there set limits because this is at the expense of the shares of other additives. That affects something when the cement bindability because the spaces between the polystyrene particles get bigger and bigger not filled enough anymore and often on top of that smooth surfaces of the polystyrene particles are therefore not are more adequately enclosed with cement.
Sand wird daher zum Füllen dieser Hohlräume weiterhin als notwendiger Hauptzuschlagstoff angesehen.Sand will therefore continue to fill these cavities regarded as a necessary main aggregate.
Sand ist aber im erheblich Umfang dafür verantwortlich, daß Bausteine trotzt des relativ hohen Anteiles von Po lystyrol immer noch zu schwer sind und noch eine zu ge ringe Wärmedämmung aufweisen. Damit werden diese Bau steine gerade den immer höher werden Ansprüchen zur ver besserten Wärmedämmung nicht mehr gerecht.However, sand is largely responsible for that building blocks defy the relatively high proportion of Po lystyrene are still too heavy and another too rings have thermal insulation. This will make this construction stones just to meet the ever increasing demands better thermal insulation no longer do justice.
Weiterhin führt Sand durch seine Salpeteranteile zu den unbeliebten Ausblühungen an den Oberflächen der Baustei ne.Sand also leads to the through its nitrate components unpopular efflorescence on the surfaces of the component no
Es besteht daher die Aufgabe, die Bestandteile von Sand bei Leichtbetonbausteinen der vorliegenden Gattung wei testgehend zu verringern.It is therefore the task of the constituents of sand with lightweight concrete blocks of the present type white test to reduce.
Diese Aufgabe wird dadurch gelöst, daß als Zuschlagstoff ausschließlich granuliertes und/oder aufgeschäumtes Po lystyrol verwendet wird und das Polystyrol aus Polysty rolpartikeln und Polystyrolmehl besteht.This object is achieved in that as an aggregate exclusively granulated and / or foamed bottom lystyrene is used and the polystyrene from polysty roll particles and polystyrene flour.
Die erfindungsgemäß benötigten Polystyrolpartikel und das Polystyrolmehl wird durch die herkömmlichen Zerklei nerungsverfahren aus dem handelsüblichen Granulat oder dem stangenförmigen Halbzeug gewonnen. Auch vergaste Po lystyrolpartikel bzw. Styropor sind verwendungsfähig. Es ist zweckmäßig, Polystyrolpartikel mit unterschiedli chen Korngrößen herzustellen und einzusetzen. Besonders vorteilhaft ist es, das Polystyrol aus der Zerkleinerung von gealtertem, insbesondere aus recyclen fähigem Altpolystyrol zu gewinnen. Das trägt außerdem zur Umweltschonung bei.The polystyrene particles and The polystyrene flour is made through the traditional pulping recovery process from the commercially available granules or won the rod-shaped semi-finished product. Gassed butt too Lystyrene particles or styrofoam can be used. It is useful to polystyrene particles with differ to produce and use grain sizes. It is particularly advantageous to remove the polystyrene from the Shredding of aged, especially from recycled able to recover old polystyrene. That also carries to protect the environment.
Dieser neuartige Leichtbetonbaustein besitzt hervorra gende Eigenschaften.This new lightweight concrete building block has Hervra properties.
Auf Grund der Substitution von Sand durch ausschließlich Polystyrol ist die Verwendung eines höchsten Anteiles von Polystyrolbestandteilen möglich. Der Leichtbetonbau stein wird daher äußerst massereduziert und läßt sich so leicht verarbeiten. Besonders in der Großplattenbauweise kommt dieser Vorteil sehr zur Geltung. Due to the substitution of sand with exclusively Polystyrene is the use of a high proportion of polystyrene components possible. The lightweight concrete construction stone is therefore extremely reduced in mass and can be so easy to process. Especially in the large plate construction this advantage comes into its own.
Noch bedeutsamer sind die mit diesem Baustein erzielten Wärmedämmeigenschaften, da der Baustein mit Ausnahme des Zementes aus porigem Material besteht.Even more important are those achieved with this module Thermal insulation properties, since the building block with the exception of Cement consists of porous material.
Durch die unterschiedlichen Korngrößen der Polystyrol partikel und des feinen Polystyrolmehles wird die Bil dung von Hohlräumen vermieden, was sich vorteilhaft auf die Bindigkeit der Mischung und damit auf die Festigkeit des Bausteines auswirkt.Due to the different grain sizes of the polystyrene particles and fine polystyrene flour is the Bil formation of cavities avoided, which is advantageous on the cohesion of the mixture and thus the strength of the building block affects.
Der Leichtbetonbaustein ist daher besonders geeignet für den Bau von Außenwänden mit einer optischen oder funk tionellen Außenverblendung.The lightweight concrete block is therefore particularly suitable for the construction of external walls with an optical or radio tional external veneer.
Bei Innenwänden ist es von Vorteil, den Leichtbetonbau stein mit Gipsputz, Kaltputz, Fliesen oder Klinkern zu verkleiden.In the case of interior walls, it is advantageous to use lightweight concrete stone with gypsum plaster, cold plaster, tiles or clinker dress up.
Zur Verbesserung der Witterungsbeständigkeit werden Leichtbetonbausteine, die nicht verkleidet eingesetzt werden, mit einer handelsüblichen Versiegelung versehen.To improve weather resistance Lightweight concrete blocks that are not used clad are provided with a commercially available seal.
