Description
Zusatzmittel für hydraulische Bindemittel Die Erfindung betrifft die Zusammensetzung eines Zusatzmittels, insbesondere für hydraulische Bindemittel zur Beschleunigung des Abbindens und Aushärtens sowie zum Plastifizieren und als Gefrierschutz.Additive for hydraulic binders The invention relates to Composition of an additive, especially for hydraulic binders for Accelerated setting and hardening as well as plasticizing and anti-freeze protection.
Im modernen Bauwesen müssen die Gebäude möglichst schnell und stabil errichtet werden, ohne dass hierdurch eine Erhöhung der Gestehungskosten aufgrund des zur Anwendung gelangenden Materials auftritt.In modern construction, buildings have to be as fast and stable as possible can be built without this resulting in an increase in the prime costs of the material used occurs.
Die hydraulischen Bindemittel sind hierfür besonders geeignet wegen ihrer Festigkeit und Verarbeitbarkeit, so dass man immer wieder versucht, die Qualität dieser Bindemittel durch den Zusatz verschiedener Produkte zu verbessern.The hydraulic binders are particularly suitable for this purpose their strength and workability, so that one tries again and again to improve the quality improve these binders by adding various products.
Formiate können auch hierbei unter den gleichen Bedingungen angewendet werden, indem sie untereinander gemischt oder mit einem weiteren Zusatz von Kalium-Verbindungen, Acetaten, Aluminaten, Ca rbonaten, Ligno 5 ulfiten, Lignosulfonaten, T riathanolaminen, Permanganaten, Stearaten vermischt sind.Formates can also be used here under the same conditions be mixed with each other or with a further addition of potassium compounds, Acetates, aluminates, carbonates, lignosulfites, lignosulfonates, triethanolamines, Permanganates, stearates are mixed.
Selbstverständlich ist die angegebene Zusatzmenge veränderbar und ergibt sich je nach der gewünschten Widerstandsfähigkeit und der Abbindegeschwindigkeit des Bindemittels.Of course, the specified additional amount can be changed and depends on the desired resistance and the setting speed of the binder.
PATENTANSPRUECHE Zusatzmittel insbesondere für hydraulische Bindemittel zur Beschleunigung des Abbindens und Aushärtens sowie zum Plastifizieren und als Gefrierschutz, gekennzeichnet durch einen Gehalt an Formiaten reiner oder/und technisch reiner Qualität. PATENT CLAIMS Additive, especially for hydraulic binders to accelerate setting and hardening as well as for plasticizing and as Antifreeze, characterized by a content of pure and / and technical formats pure quality.
2. Mittel nach Anspruch 1, gekennzeichnet durch einen Gehalt an Kaliumverbindungen und/oder Acetaten und/oder Aluminaten und/oder Carbonaten und/oder Lignosulfonaten und/oder Permanganaten und/oder Stearaten, welche in Oelen oder anderen Lösungsmitteln gelöst sein können. 2. Agent according to claim 1, characterized by a content of potassium compounds and / or acetates and / or aluminates and / or carbonates and / or lignosulfonates and / or permanganates and / or stearates, which in oils or other solvents can be solved.
3. Mittel nach Anspruch 1, gekennzeichnet durch einen Gehalt an T r iäthanolamin. 3. Means according to claim 1, characterized by a content of T r iethanolamine.
4. Verfahren zur Anwendung des Zusatzmittels nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass es Holzfasern vor oder nach deren Mineralisierung oder bei der Herstellung gewöhnlichen Zementes zugemischt wird. 4. A method for using the additive according to claim 1 to 3, characterized in that there are wood fibers before or after their mineralization or is mixed with ordinary cement during production.
Hierftir sind Zusatzmittel im Handel, welche im wesentlichen auf der Basis von Chlor aufgebaut sind. Diese Produkte auf Chiorbasis bewirken jedoch die Gefahr einer Korrosion der Armierung und aller sonstiger Eisenteile, welche in dem Beton verarbeitet werden.There are additives for this in the trade, which are essentially based on the Based on chlorine. However, these chlorine-based products do that Risk of corrosion of the reinforcement and all other iron parts that are in the Concrete to be processed.
Zweck der vorliegenden Erfindung ist die Vermeidung dieses Nachteiles und die Schaffung eines Zusatzmittels, insbesondewfUr hydraulische Bindemittel, wie Beton, Mörtel od.dgl., welches gleichzeitig zur Beschleunigung des Abbindens und Aushärtens sowie zum Plastifizieren und als Gefrierschutz dient. Dieses Zusatzmittel hat den wesentlichen Vorteil, dass es nicht korrodierend auf die Armierung und andere Metallteile wirkt, die in dem Beton enthalten sind.The purpose of the present invention is to avoid this disadvantage and the creation of an additive, especially for hydraulic binders, Such as concrete, mortar or the like. Which at the same time to accelerate the setting and curing as well as for plasticizing and antifreeze. This additive has the major advantage that it is non-corrosive to reinforcement and others Metal parts that are contained in the concrete acts.
Darüber hinaus verändert die Zumischung des erfindungsgemässen Zusatzmittels in keiner Weise die Widerstandsfähigkeit und die Endhärte des Betons oder Mörtels, sondern verbessert im Gegenteil deren Qualität hinsichtlich der Widerstandsfähigkeit im Vergleich zu einem Beton, welcher dieses Zusatzmittel nicht enthält.In addition, the admixture of the additive according to the invention changes in no way the resistance and final hardness of the concrete or mortar, on the contrary, it improves their quality in terms of resistance compared to a concrete which does not contain this additive.
Durch die plastifizierende Wirkung des erfindungsgemassen Zusatzmittels besitzt der Beton oder Mörtel nach dem Ausschalen eine.Due to the plasticizing effect of the additive according to the invention does the concrete or mortar have a.
bessere Aussenflbche, welche wesentlich leichter auf dem rohen Beton bearbeitet werden kann Das erfindungsgemässe Zusatzmittel gestattet ferner die Herstellung von Formteilen und Konstruktionen aus Leichtbeton unter Verwendung von Holzfasern, wobei die gleichen Vorteile erzielt werden wie bei einem gewöhnlichen Beton oder Mörtel, d.h. insbesondere die Möglichkeit zur Einarbeitung von Armierungen oder anderen Metallteilen ohne Gefahr einer Korrosion, verbunden mit einer erhöhten Widerstandsfähigkeit und einer besseren Au8senfliche.better outside surface, which is much easier on the raw concrete can be processed The additive according to the invention also allows production of molded parts and structures made of lightweight concrete using wood fibers, with the same advantages as with an ordinary concrete or Mortar, i.e. in particular the possibility of incorporating reinforcements or other metal parts without the risk of corrosion, combined with increased resistance and a better exterior.
