Abstract
Description
Auf Bauteile, wie Fundamente, Kellerwände, Untergeschosse, Be hälterwände usw. kann Wasser in recht unterschiedlicher Weise einwirken. Um Schäden zu vermeiden und die Funktionstüchtigkeit der Bauwerke zu erhalten, dichtet man gegen Feuchtigkeit und drückendes Wasser ab.On components such as foundations, basement walls, basements, Be container walls, etc. can use water in quite different ways act. To avoid damage and functionality to preserve the buildings is sealed against moisture and pressing water.
Ist die Abdichtung nicht mehr intakt, kommt es grundsätzlich zu Schädigungen an den Bauwerken. Man kann die Schäden einteilen in mechanische, biologische und chemische Korrosion.If the seal is no longer intact, it basically happens Damage to the structures. The damage can be divided into mechanical, biological and chemical corrosion.
Zu den mechanischen Schäden rechnen Frost- und Salzsprengungen. Sie haben ihre Ursachen in Volumenvergrößerungen beim Gefrieren von Wasser bzw. beim Kristallisieren von Salzen.Frost and salt blasts count towards mechanical damage. They have their causes in volume increases when freezing of water or when crystallizing salts.
Die biologischen Schädigungen sind zurückzuführen auf den Befall von Außen- und Innenwänden mit Mikroorganismen. Ein besonders bekanntes Beispiel dafür ist der Schimmelbefall in Gebäudeek ken.The biological damage is due to the infestation of external and internal walls with microorganisms. A special one A well-known example of this is mold growth in Gebäudeek ken.
Unter chemischer Verwitterung versteht man in diesem Zusammen hang die Zerstörung von Bausubstanz durch die Aufnahme von ag gressiven Stoffen, die im Bodenwasser gelöst sind.Chemical weathering is understood in this context hang the destruction of building fabric by inclusion of ag gressive substances that are dissolved in the soil water.
Aufgenommen werden Wässer bzw. wäßrige Lösungen von Bauwerken nach unterschiedlichen Mechanismen; hier sind besonders wichtig: die kapillare Wasseraufnahme, die Wasseraufnahme durch Sicker- und drückendes Wasser, die hygroskopische Wasseraufnahme und die Kapillarkondensation.Waters or aqueous solutions of buildings are taken up according to different mechanisms; here are particularly important: the capillary water absorption, the water absorption by seepage and pressing water, hygroscopic water absorption and the capillary condensation.
Will man die Wasseraufnahme über diese Mechanismen unterbinden, so muß die Abdichtung (Isolierung) in voller Funktionstüchtig keit geschaffen oder wieder hergestellt werden.If you want to prevent water absorption using these mechanisms, the seal (insulation) must be fully functional created or restored.
Als einfaches Verfahren, d. h. besonders preiswert und wirksam, wird heute die Verkieselung nach der Bohrlochmethode angewandt.As a simple process, i. H. particularly inexpensive and effective, Today, silicification using the borehole method is used.
Bei dieser Methode der Abdichtung von Bauwerken, werden Bohr löcher im Abstand von ca. 10 cm in das Mauerwerk getrieben und danach Wasserglaslösung eingebracht.With this method of sealing buildings, Bohr holes in the masonry at a distance of approx. 10 cm and then water glass solution introduced.
Die Wasserglaslösung kann mittels Überdruck oder Normaldruck injiziert werden. Die Druckinjektion wird meist bei größeren Schäden durchgeführt, während kleinere Durchfeuchtungsschäden einfacher mit Spritzflaschen oder Handkannen saniert werden.The water glass solution can be applied using overpressure or normal pressure be injected. The pressure injection is usually larger Damage done while minor wetting damage easier to renovate with wash bottles or hand cans.
Die Wasserglaslösungen diffundieren aus dem Bohrloch in das umgebende Mauerwerk und bilden dort Kieselgel bzw. verbinden sich mit den Calcium- und Aluminiumverbindungen des Mauerwerks zu unlöslichen Silikaten. Auf diese Weise entsteht eine wasser feste Dichtungsschicht. The water glass solutions diffuse from the borehole into the surrounding masonry and form silica gel or connect there with the calcium and aluminum compounds of the masonry to insoluble silicates. This creates a water solid sealing layer.
Nachteilig an diesem und ähnlichen Verfahren ist jedoch die geringe Flexibilität der entstehenden Dichtungsschichten. Dies gilt auch für hydrophobierte Wasserglaslösungen. Aufgabe der dem Wasserglas zugesetzten Hydrophobierungsmittel (Silikonate, Fett säureverbindungen u. a.) ist es, durch Kapillardepression das Eindringen von Wasser zu vermindern. Die Flexibilität und Rißbe ständigkeit der Sperrschicht wäre andererseits aber besonders wichtig, um eine dauerhafte Abdichtung auch bei Vibrationen (hervorgerufen z. B. durch Pkw- und Lkw-Verkehr, Flugzeuger schütterungen usw.) oder bei geringen Bodenabsenkungen zu ge währleisten.The disadvantage of this and similar processes, however, is that low flexibility of the resulting sealing layers. This also applies to water-repellent water glass solutions. Task of the Water repellent added to water glass (siliconates, fat acid compounds and. a.) it is that by capillary depression Reduce water ingress. The flexibility and Rißbe on the other hand, durability of the barrier layer would be special important for a permanent seal even with vibrations (caused e.g. by car and truck traffic, aircraft vibrations, etc.) or with slight subsidence guarantee.
Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, die an sich bekannten Wasserglaslösungen so zu verändern, daß die bei der Anwendung entstehenden silikatischen Sperrschichten ihre nachteilige Sprödigkeit und Rißanfälligkeit verlieren.The present invention was therefore based on the object to change known water glass solutions so that the silicate barrier layers that develop during use lose disadvantageous brittleness and susceptibility to cracking.
Diese Aufgabe wurde erfindungsgemäß dadurch gelöst, daß Wasser glaslösungen mit oder ohne Hydrophobierungsmittel faserförmige Stoffe mit geringen Längenabmessungen zugesetzt werden.This object was achieved in that water glass solutions with or without fibrous hydrophobizing agent Substances with small length dimensions can be added.
In einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung werden den Wasserglaslösungen Carbonfasern (Kohlenstoff-Fasern) zugesetzt.In a particularly preferred embodiment of the present Carbon fiber is the invention of water glass solutions (Carbon fibers) added.
Die Gehalte der Wasserglaslösungen an Carbonfasern betragen nach einem weiteren Merkmal der Erfindung 10 bis 0,01% und beson ders bevorzugt 1 bis 0,01%.The carbon fiber content of the water glass solutions is: another feature of the invention 10 to 0.01% and esp more preferably 1 to 0.01%.
Wasserglaslösungen sind Kalium- und Natriumsilikate in wäßriger bzw. wäßrig-kolloidaler Lösung. Die Lösungen werden durch das Molverhältnis Siliciumdioxid zu Alkalimetalloxid oder mittels ihrer Dichten charakterisiert. Kaliwasserglas 30, z. B. enthält bei einer Dichte von ca. 1,25 kg/l 30% Festglas bei einem Mol verhältnis von etwa 4. Die Viskosität der Lösung beträgt ca. 8 mPa s.Water glass solutions are potassium and sodium silicates in aqueous and aqueous colloidal solutions. The solutions are characterized by the molar ratio of silicon dioxide to alkali metal oxide or by means of their densities. Potash water glass 30 , e.g. B. contains at a density of about 1.25 kg / l 30% solid glass with a molar ratio of about 4. The viscosity of the solution is about 8 mPa s.
Alle Wasserglaslösungen reagieren stark alkalisch. Säuren, saure Salze und selbst Kohlensäure und Hydrogencarbonat setzen aus den Lösungen Kieselsäuren frei, die sich als Gel niederschlagen und mit den Komponenten im Mauerwerk weiterreagieren.All water glass solutions react strongly alkaline. Acids, acid Salts and even carbon dioxide and bicarbonate form from the Solutions free silicas, which are deposited as a gel and continue to react with the components in the masonry.
Für die erfindungsgemäßen Verkieselungsmittel werden bevorzugt Kaliwasserglaslösungen verwendet, da diese im Gegensatz zu den Natronwasserglaslösungen nicht zum Ausblühen neigen.For the silicification agents according to the invention are preferred Potash water glass solutions are used, as opposed to the Soda water glass solutions do not tend to bloom.
Als faserförmige Stoffe entsprechend Anspruch 1 dieser Erfindung kann man Glasfasern, synthetische und natürliche Polymerfasern oder bevorzugt Carbonfasern verwenden.As fibrous materials according to claim 1 of this invention you can use glass fibers, synthetic and natural polymer fibers or preferably use carbon fibers.
Glasfasern sind schon lange bekannt und ihre Herstellung sowie Eigenschaften gehören zum Stand der Technik. Bevorzugt im Rahmen dieser Erfindung werden dünne (1-100 um) und kurze (1-0,1 mm) Glasfasern eingesetzt. Diese Glasfasern verteilen sich in den Wasserglaslösungen und bilden bei der Ausbreitung im Mauer werk Glasfaser-verstärkte Kieselgelschichten. Man erhält so gegen Erschütterungen und Senkungen stabile Dichtschichten.Glass fibers have long been known and their manufacture as well Properties belong to the state of the art. Preferably in the frame This invention uses thin (1-100 µm) and short (1-0.1 mm) glass fibers are used. These glass fibers are distributed in the water glass solutions and form when spreading in the wall werk Glass fiber reinforced silica gel layers. You get like this sealing layers stable against vibrations and subsidence.
Ein Nachteil der Glasfasern besteht darin, daß sich diese lang sam in den Wasserglaslösungen auflösen oder zumindest angegrif fen werden.A disadvantage of glass fibers is that they are long sam dissolve in the water glass solutions or at least attacked be opened.
Carbonfasern weisen diese Nachteile nicht auf, und werden des halb bevorzugt eingesetzt.Carbon fibers do not have these disadvantages, and are the half preferably used.
Carbonfasern, auch Kohlenstoff-Fasern oder Graphit-Fasern ge nannt, werden durch Pyrolyse von organischen Verbindungen gewon nen.Carbon fibers, including carbon fibers or graphite fibers are obtained by pyrolysis of organic compounds nen.
Carbonfasern sind bis zu Temperaturen von 2000°C bruchfest, viermal leichter als Stahl, korrosionsbeständig und elastisch. Die mittlere Zugfestigkeit liegt bei 2 bis 3 kN/mm2, der ent sprechende E-Modul beträgt ca. 300 kN/mm2.Carbon fibers are unbreakable up to temperatures of 2000 ° C, four times lighter than steel, corrosion-resistant and elastic. The average tensile strength is 2 to 3 kN / mm 2 , the corresponding modulus of elasticity is approx. 300 kN / mm 2 .
Für das erfindungsgemäße Verkieselungsmittel werden den Wasser glaslösungen Carbonfasern in Mengenanteilen von 10 bis 0,01% zugesetzt. Die Länge der verwendeten Fasern kann in weiten Gren zen schwanken. Damit die Carbonfasern mit der Wasserglaslösung jedoch in die Haarrisse und Poren des Mauerwerks einsickern können, sollen die Carbonfasern 1 bis 2 mm Länge nicht über schreiten. Besonders bewährt haben sich Längen zwischen 1 und 0,05 mm.For the silicification agent according to the invention, carbon fibers are added to the water glass solutions in proportions of 10 to 0.01%. The length of the fibers used can vary widely. So that the carbon fibers with the water glass solution can seep into the hairline cracks and pores of the masonry, the carbon fibers should not exceed 1 to 2 mm in length. Lengths between 1 and 0.05 mm have proven particularly useful.
Die bei der Bohrlochisolierung entstehenden Dichtungsschichten aus Kieselgel und Metallsilikaten werden durch die eingebetteten Carbonfasern zu flexiblen Sperrschichten umgewandelt, welche die nachteiligen Eigenschaften der reinen Wasserglasschichten, näm lich mangelnde Riß- und Dehnbeständigkeit nicht mehr aufweisen. Die mit den erfindungsgemäßen Verkieselungslösungen hergestell ten Sperrschichten sind in vorteilhafter Weise gegen Mauerwerks dehnungen, Bodensenkungen oder -hebungen viel weniger anfällig als Dichtschichten auf Basis von reinem Wasserglas mit oder ohne Hydrophobierungsmittel.The sealing layers that arise during well insulation from silica gel and metal silicates are embedded by the Carbon fibers converted to flexible barrier layers, which the adverse properties of pure water glass layers, näm no longer exhibit insufficient resistance to cracking and stretching. Prepared with the silicification solutions according to the invention th barrier layers are advantageously against masonry strains, subsidence or subsidence much less susceptible as sealing layers based on pure water glass with or without Water repellents.
Zur Herstellung der beanspruchten Wasserglaslösungen mit faser förmigen Stoffen wird in einfacher Weise die abgewogene Menge Fasermaterial unter leichtem Rühren in die Wasserglaslösung eingebracht.For the production of the claimed water glass solutions with fiber shaped substances is the weighed amount in a simple manner Fiber material with gentle stirring in the water glass solution brought in.
Die entstehenden Suspensionen neigen zum langsamen Absetzen, sind sonst aber stabil. Durch Umschütteln oder Aufrühren, kurz vor der Verarbeitung, kann man aber leicht die Mischungen wieder homogenisieren und anwendungsfertig erhalten.The resulting suspensions tend to slowly settle, are otherwise stable. By shaking or stirring, briefly before processing, but you can easily mix again homogenize and get ready for use.
