Abstract
Description
Es wurde gefunden, das Zinn-II-Chlorid multifunktional als Promotor zur Erhöhung der Frühfestigkeit und Qualitätsverbesserung bei der Herstellung von hydraulisch abbindenden Systemen eingesetzt werden kann. Die Applikation erfolgt zum Zementklinker im Mahlprozess.It The tin-II chloride was found to be multifunctional as a promoter to increase the early strength and quality improvement be used in the manufacture of hydraulic setting systems can. It is applied to the cement clinker in the grinding process.
1. Verlust an Frühfestigkeit einer hydraulisch abbindenden Masse1. Loss of early strength a hydraulically setting mass
Es wird beobachtet, dass in hydraulisch abbindenden Massen oftmals die Frühfestigkeit negativ (verzögert) beeinflusst wird und damit Qualitätseinbußen hingenommen werden müssen.It it is observed that in hydraulically setting masses the early strength negative (delayed) is affected and thus losses in quality have to be accepted.
Eine solche Verzögerung kann verschiedene Ursachen haben, allerdings wird dieser Effekt besonders durch Einsatz des Chromatreduktor Eisen-II-Sulfat in verstärktem Maße beobachtet. Deshalb soll diese Tatsache hier als Beispiel beschrieben werden.A such delay can have different causes, however this effect observed to an increased extent, in particular by using the chromate reducer iron-II-sulfate. Therefore, this fact will be described here as an example.
Der Grund hierfür ist, dass Eisen-II-Sulfat sehr hoch dosiert werden muss, um eine minimale Lagerstabilität im Zement garantieren zu können. Hierdurch steigt die Sulfatlast derartig stark an das die hydraulisch abbindende Masse verzögert wird, mit der Folge, dass die Frühfestigkeit erheblich reduziert werden kann.The reason for that is that iron-II-sulfate has to be dosed very high in order to get one minimal storage stability to guarantee in the cement. hereby the sulfate load increases so much that the hydraulically setting one Mass delayed is, with the result that the early strength can be significantly reduced.
Es wurde gefunden, dass durch Zugabe von Zinn-II-Chlorid in Verbindung mit Triethanolamin, bevorzugt als Flüssigkeit, appliziert zum Zementklinker im Mahlprozess die Frühfestigkeiten wieder auf das gewünschte Maß gebracht werden können. Weiterhin reduzieren die Zinn-II-Ionen des Zinn-II-Chlorids Chromate und kann so zum Wegfall von zusätzlichen Chromatreduktoren bzw. deren Minderung beitragen. Infolgedessen wird so der Sulfateintrag je nach Gegebenheit gestoppt oder reduziert. Zusammenfassend bedeutet das, die Frühfestigkeit wird durch die Kombination von Zinn-II-Chlorid und Triethanolamin wesentlich gesteigert und zweitens kann ein zusätzlicher Sulfateintrag durch ein Chromatreduktionssystem vermieden werden.It it was found that by adding tin-II chloride in combination with triethanolamine, preferably as a liquid, applied to the cement clinker in the Grinding process the early strengths back to the desired one Made to measure can be. Furthermore, the tin-II-ions of the tin-II-chloride reduce chromates and can thus eliminate the need for additional chromate reducers or contribute to their reduction. As a result, the sulfate entry stopped or reduced depending on the circumstances. In summary, means that, the early strength becomes essential through the combination of tin-II-chloride and triethanolamine increased and secondly, an additional sulfate entry through a chromate reduction system can be avoided.
Standartrezeptur:Standard recipe:
- 25 % Zinn-II-Chlorid (41%ig)25% tin-II-chloride (41%)
- 50 % Triethanolamin50% triethanolamine
- 25 % Wasser.25% water.
2. Verbesserung der Zementqualität2. Improvement the cement quality
Es wurde gefunden das durch Zugabe von Zinn-II-Chlorid zum Zementklinker die Standartqualität 32,5 auf 42,5 angehoben werden kann.It was found by adding tin-II-chloride to the cement clinker the standard quality 32.5 to 42.5 can be raised.
Standartrezeptur:Standard recipe:
- 25 % Wasser25% water
- 25 % Zinn-II-Chlorid25% stannous chloride
- 50 % Monoethylenglykol.50% monoethylene glycol.
Je nach technischem Anspruch ist die Glykolkomponente dem Zementklinker anzupassen, oder ggf. auch durch Rhodanit, Naphthalin, Lignin, Melamin, Polycarboxylate oder andere Zusatzmittel nach EN 934 einzusetzen. Optimale Ergebnissen müssen durch Versuche ermittelt werden, dies beruht auf der Tatsache das Zementklinker z.B. je nach Herkunft sich sehr stark voneinander unterscheiden können. Entsprechend müssen die vorstehenden Standartrezepturen variiert werden und deshalb ist es nicht möglich für jeden Anwendungsfall eine allgemein gültige Standartrezeptur zu entwickeln.ever According to technical requirements, the glycol component is the cement clinker adapt, or possibly also by rhodanite, naphthalene, lignin, melamine, Use polycarboxylates or other additives according to EN 934. Must have optimal results determined by experiment, this is due to the fact that Cement clinker e.g. depending on their origin very different from each other can distinguish. Must accordingly the above standard formulations are varied and therefore it is impossible for each Use case a general one Develop standard recipe.
Grundsätzlich ist es auch möglich Zinn-II-Chlorid pulverförmig der Zementklinker im Mahlprozess zuzusetzen.Basically is it is also possible tin-II-chloride powdery add the cement clinker in the grinding process.
Das Maximum der Dosierung von Zinn-II-Chlorid begrenzt sich durch das vorgeschriebene Maß an Chlorid in Baustoffen und darf nicht überschritten werden.The The maximum dosage of tin-II-chloride is limited by that prescribed level of Chloride in building materials and must not be exceeded.
