Description
Die Erfindung betrifft einen Wandputz aus einem Zement oder einem Zement enthaltenden Mörtel mit eingelagerten unbehandelten, überzugsfreien Strohfasern. Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Wandputzes.The invention relates to a wall plaster made of a cement or a cement containing mortar with embedded untreated, coating-free straw fibers. The The invention also relates to a method for producing a wall plaster.
Wandputze werden mit einer Bewehrung aus eingelagerten Fasern versehen, um zu verhindern, daß sich in einer auf eine Innenwand oder eine Außenwand gegebenenfalls unter Zwischenschaltung einer Wärmedämmschicht aufgebrachten Putzschicht Risse bilden, weil die Putzschicht wärme- oder witterungsbedingten Dehnungen der Innen- oder Außenwand bzw. der Dämmschicht nicht folgen kann. Die Bewehrung soll auch Rissbildung bei Quell- oder Schwindvorgängen in der Putzschicht verhindern. In diesem Zusammenhang ist die Verwendung verschiedener Naturfasern bereits vorgeschlagen worden, unter anderem von Baumwollfasern (DE 36 07 438), Fruchthaaren des Kapokbaumes (DE 195 06 868) oder Fasern aus Bast, Hanf, Mais und dergleichen als Bewehrung für einen Baustoff (DE 197 36 527).Wall plasters are provided with reinforcement made of embedded fibers in order to prevent yourself from sticking to an inner wall or an outer wall optionally applied with the interposition of a thermal barrier coating Plaster layer form cracks because the plaster layer is caused by heat or weather Stretches of the inner or outer wall or the insulation layer can not follow. The Reinforcement is also said to crack during swelling or shrinkage in the Prevent plaster layer. In this context, the use is different Natural fibers have already been proposed, including cotton fibers (DE 36 07 438), fruit hair of the kapok tree (DE 195 06 868) or fibers Bast, hemp, corn and the like as reinforcement for a building material (DE 197 36 527).
Nachteilig ist, daß Naturfasern, die Zellulose enthalten, im alkalischen Milieu des Putzes angegriffen werden und im Laufe der Zeit verrotten, wobei auch ihre Festigkeit abnimmt. Deshalb hat man bereits vorgeschlagen, in einen Dämmestrich für Fußbodenbeläge Naturfasern einzulagern, die gegen den Angriff durch Zement oder andere Bindemittel durch einen Überzug geschützt sind (DE 925 195). Bei wärmedämmenden Konstruktionsteilen aus einem mineralischen Bindemittel mit darin eingelagerten Naturfasern aus Schilf, Stroh, Sisal, Hanf, Baumwolle und dergleichen ist vorgeschlagen worden, die Naturfasern vor ihrer Einlagerung in das Bindemittel mit geeigneten Verrottungsschutzmitteln und anderen eigenschaftsregulierenden Materialien zu behandeln (DE 44 02 912). Unbehandelte Strohfasern sind als Bewehrung für Dämmplatten vorgeschlagen worden, deren Bindemittel ausschließlich aus natürlichen und/oder synthetischen Latices besteht (DE 198 10 862).The disadvantage is that natural fibers containing cellulose in the alkaline environment of Plasteres are attacked and rot over time, reducing their strength decreases. That is why it has already been proposed to use an insulation screed for Store flooring natural fibers that are resistant to attack by cement or other binders are protected by a coating (DE 925 195). at thermal insulation construction parts made of a mineral binder embedded natural fibers from reeds, straw, sisal, hemp, cotton and the like It has been proposed to use the natural fibers before storing them in the binder suitable anti-rot agents and other property regulating agents Treat materials (DE 44 02 912). Untreated straw fibers are considered Reinforcement for insulation boards has been proposed, the binders of which are exclusive consists of natural and / or synthetic latices (DE 198 10 862).
Ein Wandputz der eingangs beschriebenen Gattung (DE 196 24 149 A1) soll durch eingelagertes Füllmaterial, z. B. Feststoffe, Fasern und dergl., besondere Oberflächeneffekte ergeben, so dieser Wandputz eine Tapete ersetzen kann. Er soll nur innen eingesetzt werden, nicht aber als Außenputz. Ferner sind Lehm-Fertigputze bekannt, die als Zusatz getrocknetes und geschnittenes Stroh enthalten (DE 296 03 687 A1; DE 295 18 567 A1).A wall plaster of the type described at the beginning (DE 196 24 149 A1) is said to be stored filling material, e.g. B. solids, fibers and the like., Special Surface effects result, so this wall plaster can replace a wallpaper. He should can only be used inside, but not as exterior plaster. There are also ready-made clay plasters known that contain dried and cut straw as an additive (DE 296 03 687 A1; DE 295 18 567 A1).
Aufgabe der Erfindung ist es, einen einfach herzustellenden Wandputz anzugeben, der auch bei extremer witterungsbedingter Beanspruchung dauerhaft rißfrei bleibt.The object of the invention is to provide a wall plaster that is simple to produce, that remains permanently crack-free even under extreme weather-related stress.
Diese Aufgabe wird dadurch gelöst, daß die Strohfasern aus knotenfreine Abschnitten von Weizenstrohfasern bestehen. Überraschenderweise wirkt sich das alkalische Milieu im Zement oder zementhaltigen Mörtel bzw. im Putz positiv auf die Eigenschaften der Weizenstrohfasern aus. Das wird darauf zurückgeführt, daß Weizenstrohfasern einen verhältnismäßig großen Gehalt an reaktionsfähiger Kieselsäure (SiO2) und dementsprechend puzzolanische Eigenschaften haben. Sie wirken deshalb wie ein hydraulischer Zusatz zum Zement bzw. Mörtel, indem freier Kalk durch die Kieselsäure in Calciumsilicate überführt wird. Gleichzeitig steigt auch die Zug- und Druckfestigkeit der Weizenstrohfasern an, ohne daß ihre Duktilität nachteilig beeinflußt wird. Aufgrund der ablaufenden chemischen Reaktionen entsteht auch ein guter Verbund zwischen dem mineralischen Bindemittel und den eingelagerten Weizenstrohfasern sowie Schutz gegen Verrottung. Der erfindungsgemäße Wandputz kann folglich allen thermisch bedingten oder witterungsbedingten Dehnungen des Untergrundes oder der Putzschicht ohne Rißbildung folgen. Vorzugsweise können die Weizenstrohfasern eine Länge von 10 bis 25 mm besitzen.This object is achieved in that the straw fibers consist of knot-free sections of wheat straw fibers. Surprisingly, the alkaline environment in the cement or cement-containing mortar or plaster has a positive effect on the properties of the wheat straw fibers. This is attributed to the fact that wheat straw fibers have a relatively large content of reactive silica (SiO 2 ) and, accordingly, pozzolana properties. They therefore act as a hydraulic additive to the cement or mortar, in that free lime is converted into calcium silicates by the silica. At the same time, the tensile and compressive strength of the wheat straw fibers increases, without their ductility being adversely affected. Due to the chemical reactions taking place, there is also a good bond between the mineral binder and the embedded wheat straw fibers, as well as protection against rotting. The wall plaster according to the invention can consequently follow all thermally or weather-related expansions of the substrate or the plaster layer without cracking. The wheat straw fibers can preferably have a length of 10 to 25 mm.
Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Wandputzes. Das Verfahren ist dadurch gekennzeichnet, daß der Zement oder der Mörtel trocken mit den Weizenstrohfasern vermischt wird und die Mischung dann mit Wasser angemacht wird. Insbesondere können 100 Gewichtsteile Zement oder Mörtel mit 1,5 bis 2,5 Gewichtsteilen Weizenstrohfasern gemischt werden. Bei einer bevorzugten Ausführung werden 100 Gewichtsteile Zement oder Mörtel mit 2 Gewichtsteilen Weizenstrohfasern gemischt.The invention also relates to a method for producing a wall plaster. The The method is characterized in that the cement or mortar is dry with the wheat straw fibers are mixed and then mixed with water becomes. In particular, 100 parts by weight of cement or mortar with 1.5 to 2.5 parts by weight of wheat straw fibers are mixed. In a preferred one Execution will be 100 parts by weight of cement or mortar with 2 parts by weight Wheat straw fibers mixed.
Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; es zeigen: In the following an embodiment shown in the drawing Invention explained; show it:
Fig. 1 in einem Diagramm die Zerreißfestigkeit von unbehandelten Weizenstrohfasern, Fig. 1 a diagram showing the tensile strength of untreated wheat straw fibers,
Fig. 2 in einem Diagramm die Zerreißfestigkeit von Weizenstrohfasern nach Einlagerung in einer alkalischen Lösung nach CEN (bei einem pH-Wert von 12,5 bis 13,5) während 24 Stunden bei 60°Celsius, Fig. 2 a diagram of the tensile strength of wheat straw fibers after storage in an alkaline solution according to CEN (with a pH 12.5 to 13.5) for 24 hours at 60 ° Celsius,
Fig. 3 schematisch einen Schnitt durch eine verputzte Wand. Fig. 3 shows schematically a section through a plastered wall.
Einem Vergleich der Fig. 1 und 2 entnimmt man, daß die Zerreißfestigkeit von Weizenstrohfasern im alkalischen Milieu erheblich zunimmt. Das gilt auch dann, wenn Weizenstrohfasern als Bewehrung in einen Wandputz aus mineralischen Bindemitteln eingelagert werden.A comparison of FIGS. 1 and 2 shows that the tensile strength of wheat straw fibers increases considerably in an alkaline environment. This also applies if wheat straw fibers are embedded as reinforcement in a wall plaster made of mineral binders.
In Fig. 3 erkennt man eine Wand 1 als tragenden Untergrund, auf der mit einer Klebemörtelschicht 2 und Dübeln 3 eine Wärmedämmung 4 befestigt ist. Auf die Wärmedämmung 4 ist ein erfindungsgemäßer Wandputz 5 aufge tragen, der mit einem Oberputz 6 abgedeckt ist.In Fig. 3 you can see a wall 1 as a load-bearing surface on which a thermal insulation 4 is fixed with an adhesive mortar layer 2 and dowels 3 . On the thermal insulation 4 , a wall plaster 5 according to the invention is worn, which is covered with a top plaster 6 .
Zur Herstellung des Wandputzes 5 werden 100 Gewichtsteile Zement oder Mörtel trocken mit 2 Gewichtsteilen Weizenstrohfasern gemischt. Die Mischung wird anschließend mit Wasser angemacht und dann auf die Außen seite der Wärmedämmung 4 aufgetragen. Wenn der Wandputz 5 hinreichende Festigkeit erlangt hat, wird der Oberputz 6 aufgetragen.To produce the wall plaster 5 , 100 parts by weight of cement or mortar are dry mixed with 2 parts by weight of wheat straw fibers. The mixture is then mixed with water and then applied to the outside of the thermal insulation 4 . When the wall plaster 5 has achieved sufficient strength, the top plaster 6 is applied.
Der Wandputz 5 kann rißfrei allen thermisch bedingten oder witterungs bedingten Dehnungen der Wärmedämmung 4 folgen, weil die Weizenstroh fasern aufgrund ihres erheblichen Kieselsäuregehaltes (SiO2) puzzolanische Eigenschaften haben und die Kieselsäure mit dem Kalk des mineralischen Bindemittels derart reagiert, daß unter Bildung von Calciumsilicaten der Verbund zwischen den Weizenstrohfasern und dem mineralischen Bindemittel verbessert und die Zugfestigkeit der Weizenstrohfasern erhöht wird, ohne daß Verrottungsgefahr besteht.The wall plaster 5 can follow all thermal or weather-related expansions of the thermal insulation 4 without cracks, because the wheat straw fibers have pozzolanic properties due to their considerable silicic acid content (SiO 2 ) and the silicic acid reacts with the lime of the mineral binder such that the formation of calcium silicates Bond between the wheat straw fibers and the mineral binder is improved and the tensile strength of the wheat straw fibers is increased without the risk of rotting.
