Description

Herstellung eines porösen, zähen, druckfesten und rissefreien Betons Es ist bekannt, Gasbeton oder Schaumbeton herzustellen. Die Mängel des Porenbetons sind geringe Festigkeiten, ohne Dampfhärtung große Schwindneigung, große Wassersaugfähigkeit und Sprödigkeit der ganzen Masse, daher Neigung zur Rißbildung. Als Fußbodenestrich insbesondere sucht man einen fugenlosen Belag, der rißfrei bleibt, druckfest und insbesondere eindruckfest ist, sehr viele möglichst kleine, luft- und wasserdicht gegeneinander abgeschlossene Luftporen besitzt, um eine maximale Wärme- und Schalldämpfung zu erzielen, und der billig herzustellen ist.Production of a porous, tough, pressure-resistant and crack-free concrete It is known to produce aerated concrete or foam concrete. The shortcomings of aerated concrete are low strength, high tendency to shrink without steam hardening, high water absorbency and brittleness of the whole mass, hence tendency to crack. As a floor screed In particular, you are looking for a seamless covering that remains crack-free, pressure-resistant and In particular, it is resistant to impressions, very many as small as possible, airtight and watertight Has mutually closed air pores in order to achieve maximum heat and sound absorption and which is cheap to manufacture.

Nach dem bisherigen Stand der Technik waren diese Forderungen mit billigen und einfachen Mitteln nicht zu erreichen.According to the previous state of the art, these requirements were included cheap and simple means cannot be achieved.

Das Verfahren nach der vorliegenden Erfindung ermöglicht die Herstellung eines porösen, druckfesten und rißfreien Betons aus entsprödetem Zementbeton, Magnesitbeton, Wasserglasbeton oder Gipsbeton, indem man als Zuschlagstoffe eine Körnung auswählt von z. B. 3 bis 7 mm oder 3 bis 25 mm, aber immer ohne das Feinkorn o bis 3 mm oder o bis 7 mm und diese feinkornfreien Zuschläge, anorganischer und/oder organischer Art, mit so viel Bindemittel, Zement, Sorelzement, Wasserglas oder Gips, einbindet, daß noch genügend Hohlräume in der porösen Masse erhalten bleiben und zum Anmischen des hydraulischen oder anderen Bindemittels eine verdünnte bituminöse stabile Dispersion verwendet in solcher Menge, daß keine bituminöseVerkittung derZuschläge entsteht.The method according to the present invention enables the production of a porous, pressure-resistant and crack-free concrete from de-brittle cement concrete, magnesite concrete, water glass concrete or gypsum concrete by selecting a grain size of z. B. 3 to 7 mm or 3 to 25 mm, but always without the fine grain o to 3 mm or o to 7 mm and these fine grain-free aggregates, inorganic and / or organic, with as much binder, cement, Sorel cement, water glass or gypsum , that there are still enough cavities in the porous mass and a diluted bituminous stable dispersion is used to mix the hydraulic or other binding agent in such an amount that no bituminous putty of the aggregates is formed.

An Stelle von reinem Bitumen oder Teer in Emulsionsform kann man auch Wachs und/oder Harze und/oder Kunstharze und/oder gehärtete Öle und/oder Silicone, d. h. allein oder in Mischung, verwenden.Instead of pure bitumen or tar in emulsion form, you can also Wax and / or resins and / or synthetic resins and / or hardened oils and / or silicones, d. H. Use alone or in a mixture.

Diese Stoffe entspröden die hydraulischen und anderen Bindemittel, indem sie Millionen hauchdünner Gleitflächen, Gelenke oder Fugen in der Betonmasse erzeugen und die hydraulische Bindung hydrophob, also wasserabweisend, machen.These substances break the hydraulic and other binders, by making millions wafer-thin Sliding surfaces, joints or joints in the concrete mass and the hydraulic bond is hydrophobic, i.e. water-repellent, do.

Perlkies oder Rheinkies von 3 bis 7 mm Körnung besitzt beispielsweise 40% Hohlräume.Pearl gravel or Rhine gravel with a grain size of 3 to 7 mm, for example, has 40% voids.

Der poröse elastische Beton gemäß vorliegender Erfindung, z. B. im Mischungsverhältnis i : 6, besitzt nach 28 Tagen 13i,4 kg/qcm Druckfestigkeit und 45,o kg Biegezugfestigkeit. Das Verhältnis der Biegezug- . zu Druckfestigkeit ist also i : 3, d. h. außergewöhnlich günstig. Diese Masse ist zäh und bleibt rißfrei. Der Elastizitätsmodul beträgt weniger als 2oooo. Der vorstehende poröse elastische Beton war z. B. zusammengesetzt aus 11,36 kg Kies von 3 bis 7 mm Korngröße, 2,oo kg Portlandzement Dyckerhoff, 0,535 kg stabiler Bitumendispersion (50%ig), o,535 kg Wasser. Er enthielt also 3ookg/cbmZement und i,8%Bitumen.The porous resilient concrete according to the present invention, e.g. B. in the mixing ratio i: 6, has after 28 days 13.4 kg / cm 2 compressive strength and 45.o kg flexural strength. The ratio of the bending tensile. to compressive strength is therefore i: 3, ie exceptionally favorable. This mass is tough and remains free of cracks. The modulus of elasticity is less than 2,000. The above porous elastic concrete was e.g. B. composed of 11.36 kg of gravel with a grain size of 3 to 7 mm, 2.000 kg of Portland cement Dyckerhoff, 0.535 kg of stable bitumen dispersion (50%), 0.535 kg of water. So it contained 3ookg / cbm cement and 1.8% bitumen.

Ein anders zusammengesetzter poröser elastischer Beton mit einem Korn 3 bis 7 mm, einem Mischungsverhältnis mit Zement von i :6 und einem Bitumengehalt von 1,5% Spramex Zoo in Emulsionsform ergab nach 28 Tagen 9o kg/qcm Druck- und 45 kg/qcm Biegezugfestigkeit. Dieser beinahe plastisch zu nennende poröse und druckfeste Beton hat das günstige Verhältnis Biegezug- : Druckfestigkeit von i : 2. Er ist ein idealer Baustoff für die verschiedensten Zwecke und ist außergewöhnlich billig herzustellen.A differently composed porous elastic concrete with one grain 3 to 7 mm, a mixing ratio with cement of i: 6 and a bitumen content of 1.5% Spramex Zoo in emulsion form resulted in 90 kg / qcm pressure and 45 kg / qcm flexural strength. This almost plastic can be called porous and pressure-resistant Concrete has the favorable flexural strength: compressive strength ratio of i: 2 an ideal building material for a wide variety of purposes and is exceptionally cheap to manufacture.

Normaler Beton und auch Porenbeton haben infolge ihrer kapillaren Poren, die außerdem hydrophil, also wasserfreundlich sind, die schlechte Eigenschaft, Wasser zu saugen.Normal concrete and also aerated concrete have capillaries as a result of their Pores, which are also hydrophilic, i.e. water-friendly, the bad property, To suck water.

Der poröse elastische Beton, welcher nach dem Verfahren gemäß der Erfindung hergestellt ist, enthält keine kapillaren Poren, sondern die entstehenden Hohlräume der Betonmasse sind größer, die keine kapillar wirkende Saugkraft mehr besitzen. Außerdem sind die Porenwände durch den Bitumenzusatz wasserabweisend geworden und dadurch gegen Normalwasser dicht.The porous elastic concrete which is produced by the method according to FIG Invention is made, does not contain capillary pores, but the resulting Cavities in the concrete mass are larger, which no longer have a capillary suction force own. In addition, the pore walls have become water-repellent due to the addition of bitumen and therefore impervious to normal water.

Dieser poröse elastische Beton ist nicht nur für Fußbodenestriche geeignet, sondern auch als Schüttbeton zur Herstellung von Wänden und Decken für Bauten aller Art.This porous elastic concrete is not just for floor screeds suitable, but also as poured concrete for the production of walls and ceilings for Buildings of all kinds.

Bei Verwendung von Ziegelsplitt 3 bis 7 mm ist das festgestellte Raumgewicht 1,74, also gegenüber normalem, dichtem Beton von 22oo kg/cbm um 25% hohlraumreicher und leichter.When using brick chippings 3 to 7 mm is the determined volume weight 1.74, which is 25% more void than normal, dense concrete of 22oo kg / cbm and easier.
