Abstract

The invention relates to a composition for inorganic binders, comprising at least one ketone-formaldehyde condensation product on the basis of a cyclic ketone and at least one anionic or nonionic surfactant and/or a thickener, and also to building material mixtures which comprise this composition, and to the use of the composition. The compositions improve the applications properties of the binder formulations.

First claim

The invention claimed is:

1. A composition, comprising
(a) at least one cyclohexanone/formaldehyde/sulfite condensation product, and
(b) at least one anionic or nonionic surfactant comprising an α-sulfo-C8-C18 fatty acid disalt and at least one thickener wherein the thickener is a cellulose ether, and
wherein a weight ratio of component (a) to component (b) is in the range from 3:1 to 1:17 8/9, and wherein a weight ration of the component (a) to the thickener is in the range from 0.3:1 to 1:13 8/9.

2. The composition according to claim 1 , wherein the weight ratio of component (a) to component (b) is in the range from 3:1 to 1:5.

3. The composition according to claim 2 , wherein the weight ratio of component (a) to component (b) is in the range from 1:2 to 1:5.

4. The composition according to claim 1 , which is in powder and/or granule form.

5. The composition according to claim 4 , obtained by co-spray drying of a mixture comprising components (a) and (b).

6. A building material mixture, comprising the composition according to claim 1 and an inorganic binder.

7. The building material mixture according to claim 6 , wherein the inorganic binder is a hydraulic or latent hydraulic binder or a mixture thereof.

8. A method of improving application properties of a building material formulation, the method comprising: adding the composition according to claim 1 to the building material mixture comprising an inorganic binder.

9. A composition, comprising
(a) at least one cyclohexanone/formaldehyde/sulfite condensation product, and
(b) at least one anionic or nonionic surfactant comprising an α-sulfo-C8-C18 fatty acid disalt and at least one thickener, wherein the thickener is a cellulose ether, and

wherein a weight ratio of component (a) to component (b) is in the range from 3:1 to 1:10, and
wherein a weight ratio of component (a) to the thickener is in the range from 1.5:1 to 1:16 2/3.
