Description
Verfahren zur Herstellung von Betonmauerwerk. Zusatz zum Patent 338552 Das Verfahren gemäß dem Patent 338552 zur Herstellung von Betonmauerwerk beruht auf der Verwendung von zwei -verschiedenen Mischungen, indem Sand oder ähnliche Stoffe in mageren Mischungsverhältnis mit hydraulischen Bindemitteln zu Körpern verarbeitet, nach dem Trocknen zerkleinert und dann als Zuschlagstoff zur zweiten Mischung benutzt werden. Da alle hydraulischen Bindemittel jedoch sehr im, Preise gestiegen sind, bezweckt die vorliegende Erfindung für diese einen billigen Ersatz zu schaffen.Method of making concrete masonry. Addendum to patent 338552 The method according to the patent 338552 for the production of concrete masonry is based on the use of two -different mixtures by adding sand or similar Substances in a meager mix ratio with hydraulic binders to form bodies processed, crushed after drying and then used as an aggregate for the second Mixture can be used. However, since all hydraulic binders are very expensive have increased, the present invention aims to provide a cheap replacement for them to accomplish.
Erreicht wird dieser Zweck dadurch, daß als Ausgangstoffe zur Herstellung des künstlichen Schotters Brennstoffrückstände, insbesondere Braunkohlenasche, benutzt werden. Es ist bereits bekannt, Braunkohlenasche o. dgl. als Zuschlag zu verwenden, jedoch maßte dieselbe erst besonderen Verfahren unterworfen werden, uni: die in der Asche enthaltenen Sulfide-unschädlich ztt machen, wodurch wiederum aber die Herstellungskosten derartiger Betonmauerwerke bedeutend erhöht werden. - Nur so können bei den bis jetzt bekannten Verwendungsarten von Braunkohlenasche die durch die Sulfide hervorgerufenen Treiberscheinungen im Mauerwerk vermieden werden.This purpose is achieved in that as starting materials for production of the artificial gravel, fuel residues, in particular lignite ash, are used will. It is already known to use lignite ash or the like as an additive, however, it was first to be subjected to special procedures, uni: those in the sulfides contained in the ash harmless ztt, which in turn, however, the Manufacturing costs of such concrete masonry are significantly increased. - Only this way can with the previously known types of use of lignite ash through the sulphides caused drifting phenomena in the masonry are avoided.
Gemäß denn vorliegenden Verfahren werden Braiunkohlengsche oder ähnliche Stoffe, gemahlen oder ungemahfen, ohne oder mit Zusatz von Sand, Kalk, Kieselgar, Ton o. dgl., je nach der Bindekraft der Asche mit Wasser vermischt zu Formsingen verambeitet, die nach dem Trocknen zerkleinert werden und einen künstlichen Schotter ergeben. Dieser Schotter wird mit einer anderen Mischung aus Zement, Kalk oder ähnlichen Bindemitteln in der gewollten Weise verarbeitet.According to the present method, lignite or similar are Substances, ground or unmilled, with or without the addition of sand, lime, kieselgarden, Clay or the like, mixed with water, depending on the binding power of the ash, to form singing processed, which are crushed after drying and an artificial gravel result. This crushed stone is made with another mixture of cement, lime, or the like Binding agents processed in the intended way.
Sollten in der Braunkohlenasche schädliche Stoffe, Sulfide, gewesen sein, so können diese doch keine Wirkung mehr ausüben, da sie in den einzelnen Schotterteilen in zu geringem Maße vorhanden sind. Auch werden sie durch die Bestandteile der zweiten Mischung unschädlich gemacht, zum mindesten aber so verteilt, daß eine sichtbare oder fühlbare Wirkung nicht mehr eintreten kann.There should have been harmful substances, sulphides, in the lignite ash be, these can no longer have any effect, since they are in the individual gravel parts are insufficiently available. They also become through the constituents of the second Mixture rendered harmless, but at least distributed in such a way that a visible one or a noticeable effect can no longer occur.
Wenn Asche mit großer Bindekraft und Reinheit zur Verf'ü'gung steht, dann kann man dieselbe auch mit mehr oder weniger Zementzusatz für die zweite Mischung verwenden, um, damit den künstlichen Schotter zu binden.If ash is available with great cohesiveness and purity, then you can do the same with more or less cement addition for the second mixture use to bind the artificial gravel.
Je nach der Bindekraift und Reinheit der Asche o. dgl. ist auch das Mischungsverhältnis ebenso wie die Anwendung der verschiedenen Zuschläge, je nach ,ihrer Erreichbarkeit verschiednen; danach, richtet sich auch die Kostenersparnis, die mit diesem Verfahren verbunden ist.Depending on the binding force and the purity of the ash or the like, the mixing ratio, as well as the use of the various additives, are different depending on their availability; according to this, the cost savings associated with this process also depend.
Da das nach diesem Verfahren ausgeführte Mauerwerk aus zwei verschiedenen Teilen besteht, dem künstlichen Schotter und der zweiten Mischung zum Binden des Schotters, wirkt es sehr gut .isolierend, so daß es sich auch in dieser Hinsicht ebenso wie infolge der Kostenersparnis für Notbauten und Massensiedlungen, aber auch für jeden anderen Verwendungszweck in hervorragendem Maße eignet.Since that carried out according to this procedure Masonry consists of two different parts, the artificial gravel and the second Mixture for binding the ballast, it works very well. Isolating, so that it is also in this respect as well as as a result of the cost savings for emergency buildings and Mass settlements, but also for any other purpose in excellent Dimensions suitable.
