Abstract

The invention relates to a method for determining glycosylated haemoglobin in blood samples, glycosylated and non-glycosylated haemoglobin first being released from the erythrocytes, the haemoglobin being converted, if appropriate, into methaemoglobin and a differentiation of glycosylated and non-glycosylated haemoglobin then being carried out by means of haptoglobin. Before the differentiation of glycosylated and non-glycosylated haemoglobin by means of haptoglobin, one or more substances, which effect a change in conformation in the glycosylated and/or non-glycosylated haemoglobin, are advantageously added to the blood sample. Such substances are compounds having a binding action on the allosteric effector site of the haemoglobin, and also haeme-binding ligands. A further subject of the invention is a reagent for carrying out the method according to the invention and a reagent for differentiating glycosylated and non-glycosylated haemoglobin.

Description

Betonverzögerer, zum Verzögern von Beton oder Mörtel aufConcrete retarder, for retarding concrete or mortar

Basis von Phosphaten, frei von Alkalien.Based on phosphates, free from alkalis.

Die vorliegende Erfindung bezieht sich auf Beton-und Mörtelverzögerer auf Basis von Phosphaten, frei von Alkalien. Es ist bekannt, daß sich z.-B. Alkaliphosphate gut für die Verzögerung von Beton-oder Mörtel eignen, diese Verzögerter gelten in ihrer Wirksamkeit allgemein für hydraulische Bindemittel. Wenn aber der Beton oder Mörtel alkaliempfindlichen Zuschlag enthält, könnten solche Verzögerer nicht angewendet werden, da die Grenze der Alkaliempfindlichkeit überschritten wird und es somit zu den bekannten Alkalischäden kommt. Die Alkalireaktionen sind bekannt und beschrieben worden u.a.The present invention relates to concrete and mortar retardants based on phosphates, free from alkalis. It is known that e.g. Alkali phosphates well suited for the retardation of concrete or mortar, these retarders apply in their effectiveness in general for hydraulic binders. But if the concrete or If the mortar contains alkali-sensitive aggregate, such retarders could not be used because the limit of alkali sensitivity is exceeded and thus it comes to the well-known alkali damage. The alkali reactions are known and described been a.o.

in Dänemark von G.M. Idorn. Aus Anlaß eines schwerwiegenden Schadensfallas läßt Der Bundesminister für Verkehr nur noch Betonverzögerer auf reiner Phosphatbasis zu. ( sein Schreiben vom 2.4.1981, StB 25/58.55.10-5D'/25021 Va 811 ). In-den Fällen, wo der Beton-oder Mörtel alkaliempfindlichen Zuschlag enthält, können aber die bekannten Betonverzögerer auf Phosphatbasis nicht angewendet werden, da das in den Beton gelangende Na20-Äquivalent überschritten werden würde, die Anforderung lautet: weniger als 0,02 Gew.-, bezogen auf das Zementgewicht. Die vorliegende Erfindung erlaubt nunmehr Beton-oder Mörtel-, die alkaliempfindlichen Zuschlag enthalten, zu verzdgern, indem z.B. Phosphorsäuren, Polyphosphorsäuren oder-und Tetraphosphorsäuren neutralisiert werden mit: Ammoniak, Mono-Di-oder Triaethanolamin, andere Amine wie: z.B.in Denmark by G.M. Idorn. On the occasion of a serious claim The Federal Minister of Transport only leaves concrete retarders based on pure phosphate to. (his letter of 2.4.1981, StB 25 / 58.55.10-5D '/ 25021 Va 811). In the cases where the concrete or mortar contains alkali-sensitive aggregate, however, the known ones can be used Phosphate-based concrete retardants should not be used, as they get into the concrete Na20 equivalent would be exceeded, the requirement is: less than 0.02% by weight based on the weight of the cement. The present invention now allows Concrete or mortar, which contain alkali-sensitive aggregate, to be delayed by e.g. phosphoric acids, polyphosphoric acids or tetraphosphoric acids are neutralized are with: ammonia, mono-di- or triaethanolamine, other amines such as: e.g.

~~~ ~ Isopropanolamin, Propylamin, Dibuthylamin, wasserlösliche Amine allgemein.~~~ ~ Isopropanolamine, propylamine, dibutylamine, water-soluble amines generally.
