Abstract

For producing retarded plaster mortars or masonry mortars and also ready-mixed mortars, the required additives in addition to sand and water are mixed with the binder in a mixer. This frequently leads to wrong proportions, or the additives are confused with one another. It is the object of the invention to prevent these known deficiencies by mixing the necessary additives with hydraulic binders whilst still in the works.

Description

Hydraulische Bindemittel, die sich für die Herstellung von verzögerten Putz-oder Mauermörteln bzw. Transportmörteln eignen.Hydraulic binders that are suitable for the production of delayed Plaster or masonry mortar or transport mortar are suitable.

Die vorliegende Erfindung bezieht sich auf die Herstellung von speziell zusammengesetzten hydraulischen Bindemitteln, die sich für die Herstellung von über längere Zeit verarbeitbaren Putz-oder DIauermörteln bzw. Transportmbrteln eignen.The present invention relates to the manufacture of special composite hydraulic binders that can be used in the manufacture of over Plaster or permanent mortar or transport mortar that can be used for a longer period of time are suitable.

Es ist bekannt, daß die Verarbeitbarkeit von hydraulischen Bindemitteln durch Zugabe von Verzögerungsmitteln verlängert werden kann. Dabei ist gemeint, die Verarbeitbarkeit von Eetoii, Mörtel oder lutz. Es ist weiterhin bekannt, daß die Verarbeitbarkeit von Beton, Mörtel oder Putz durch Zugabe vori sogenannten Hilfsstoffen veibessert werden kann.It is known that the processability of hydraulic binders can be extended by adding retarders. This means the workability of Eetoii, mortar or lutz. It is also known that the workability of concrete, mortar or plaster by adding so-called auxiliary materials can be improved.

Dabei werden dem Bindemittel in einem Mischer die erforderlichen Zusatzmittel zugemischt.DOS 24 53 527 describes: Factory-mixed masonry or plaster mortar and procedures for its delivery and distribution to the construction site. Be there the required additives are added to the binder in a mixer.

DOS 22 65 352 bescilreibt: Nörtelgemiscli. Auch da werden dem Bindemittel die erforderlichen Zusatzmittel in einem Mischer zugemischt.DOS 22 65 352 describes: Nörtelgemiscli. Also there will be the binder the required additives are mixed in in a mixer.

DOS 28 01 932 beschreibt: Baustoff-Zusatzmittel. Auch hier werden in einem Mischer Bindemittel und Zusatzmittel zusammengemischt.DOS 28 01 932 describes: Building material additives. Will be here too Binder and additive mixed together in a mixer.

In den genannten Schriften werden also in einem Mischer Bindemittel, Sand, Wasser und Zusatzmittel zusammengemischt. Die Zusatzmittel selber sollen dabei bestimmte Eigenschaften des Putz-oder Maeurmörtels verändern. Einer solchen Mischung können z.E. ein, zwei, drei oder mehr Zusatzmittel zugemischt werden.In the documents mentioned, binders are used in a mixer, Sand, water and additives mixed together. The additives themselves should be included change certain properties of the plaster or mortar. Such a mix can e.g. one, two, three or more additives are mixed in.

Die Zusatzmittel werden in verschiedenen Mengen der Mischung zugegeben. Die Dosierung der Zusatzmittel kann dabei per TSand erfolgen oder mittels eines Dosierungsgerätes. Die Praxis aber l.at gezeigt, daß oft Fehlciosierungen vorkommen oder aber durch menschliches Versagen die Zusa-tzmittel verwechselt werden. Die Folge ist, daß der gewünschte Effekt nicht eintritt oder die Mischung selber unbrauchbar wird.The additives are added to the mixture in various amounts. The dosing of the additives can be done by T sand or by means of a Dosing device. However, experience at l.at has shown that false ciosings often occur or the additives are mixed up due to human error. the The result is that the desired effect does not occur or the mixture itself becomes unusable will.

ie genannten nachteile lassen sich einfach dadurch beseitigen, daß bereits im Herstellungswerk dem hydraulischen Bindemittel die einzelnen Zusatzmittel zugemischt werden. Fehldosierungen oder willkürliche Zugabe der Zusatzmittel werden dadurch ganz einfach beseitigt. Die Zusatzmittel können im Herstellungswerk, Momentwerk oder lialkwerk in verschiedener Weise dem Bindemittel beigemischt werden. Die Zusatzmittel können in Form von Pulver zugegeben werden oder in flüssiger Form aufs Bindemittel aufgesprüht werden.The disadvantages mentioned can be eliminated simply by the fact that The individual additives are added to the hydraulic binder in the manufacturing plant are mixed in. Incorrect dosages or arbitrary addition of additives thus easily eliminated. The additives can be used in the manufacturing plant, moment plant or lialkwerk can be mixed with the binder in various ways. The additives can be added in the form of powder or in liquid form on the binder be sprayed on.

Wuerpel).in @asonry Cement "e.g. an additive is added at the factory, this improves the processability of the PM binder. (III. International Symposium on cement chemistry, 1952, Ch. L. Wuerpel).

l: hydraulische 3indemittel im Sinne der Erfindung gelten alle omente einschließlich Sonderzemente, PM-Binder, hydraulische und @@@hydraulische Kalke.l: hydraulic binders in the context of the invention, all oments apply including special cements, PM binders, hydraulic and @@@ hydraulic limes.

Ein hydraulisches Bindemittel, das sich der Erfindung gemäß für die Herstellung von lange verarbeitbaren Putz-oder Maeurmörtel oder Transportmörtel eignet, kann folgende Zusammensetzung haben: hydraulisches Bindemittel, Luftporenbildner, Verzögerer, Wasserretensionsmittel, Kunststoffkomponente.A hydraulic binder, which according to the invention for Production of plaster or corn mortar or transport mortar that can be used for a long time suitable, can have the following composition: hydraulic binder, air-entraining agent, Retarder, water retention agent, plastic component.

lii diesem Beispiel wird dem hydraulischen Bindemittel soviel an Luftporenbildner zugesetzt, daß in der Puzu-oder Maeurmörtel oder Transportmörtelmischung ein Luftgehalt von z.B. 18-30% erreicht wird. Der Verzögerer wird in der Menge dem hydraulischen Bindemittel zugesetzt, daß der Erstarrungsbeginn z.B. bis zu 60 Stunden verzögert wird. Das Wasserretensionsmittel wird dem hydraulischen Bindemittel in der Menge zugesetzt, daß der damit hergestellte Putz-oder Maeurmörtel oder Transportmörtel kein Wasser mehr abstößt. Die Kunststoffkomponente wird dem hydraulischen Bindemittel in der Menge zugefügt, daß die Haftfestigkeit des Putz-oder Maeurmörtels oder Transportmörtels verbessert wird.In this example there is so much air-entraining agent in the hydraulic binder added that there is an air content in the puzu or corn mortar or transport mortar mixture of e.g. 18-30% is achieved. The retarder is hydraulic in the amount Binder added so that the start of solidification delays, for example, up to 60 hours will. The water retention agent is added to the hydraulic binder in quantity added that the plaster or corn mortar or transport mortar produced therewith no longer repels water. The plastic component becomes the hydraulic binder added in the amount that the adhesive strength of the plaster or corn mortar or transport mortar is improved.

Neben der so beschriebenen Zusammensetzung kann es oft auch genögen, wenn dem Bindemittel von den genannten Zusatzmitteln nur bestimmte zugesetzt werden.In addition to the composition described in this way, it can often also be sufficient if only certain of the additives mentioned are added to the binder.

Als Luftporenbildner können verwendet werden: Natriumresinat, Fettsäuren und deren Salze, Alkyarylsulfonate, Alkylphenolpolyglykolaether, äthoxyliertes Polypropylenglykol, Fettalkoholpolyglykolaether, Fettsäure-Eiweißkondensate, Schwefelsäureester von Ölen und Fetten, Fettsäuretauride u.a.The following can be used as air entraining agents: sodium resinate, fatty acids and their salts, alkylarylsulfonates, alkylphenol polyglycol ethers, ethoxylated polypropylene glycol, Fatty alcohol polyglycol ethers, fatty acid-protein condensates, sulfuric acid esters of Oils and fats, fatty acid taurides, etc.

Als Verzögerer können verwendet werden: Gluconsäure und deren Salze, Phosphorsäure und deren Salze, Polyphosphorsäuren und deren Salze, Ligninsulfosäure und deren Salze, Melasse, Borsäure und deren slaze, Citronensäure und deren Slaze.The following can be used as retarders: gluconic acid and its salts, Phosphoric acid and its salts, polyphosphoric acids and its salts, lignin sulfonic acid and their salts, molasses, boric acid and their slaze, citric acid and their slaze.
