The present invention refers to a settable mixture comprising (I) a water absorbing composition and (II) an aqueous emulsion of organic polymer or (III) dispersible organic polymer, wherein the water absorbing composition (I) contains inorganic ingredients which are capable to react with water and the wa~ter absorbing composition (I) contains at least 95 weight lime and wherein the amount of the aqueous emulsion of organic polymer (II) in relation to (I) is such as to provide a ratio of com~bined weight of polymer solids to combined weight of ingredi~ents which are capable to react with water of from 0.5:1 to 10:1, preferably 1:1 to 4:1 and wherein the amount of dispersible organic polymer (III) in re~lation to (I) is such as to give a ratio of combined weight of polymers to combined weight of ingredients which are capable to react with water of from 0.5:1 to 10:1, preferably 1:1 to 4:1.

La présente invention concerne un mélange durcissable contenant (I) une composition d'absorption d'eau et (II) une émulsion aqueuse d'un polymère organique ou (III) un polymère organique dispersible. La composition d'absorption d'eau (I) contient des constituants inorganiques capables de réagir avec l'eau. La composition d'absorption d'eau (I) contient également au moins 95 % en poids de chaux. La quantité d'émulsion aqueuse d'un polymère organique (II) par rapport à (I) est telle que l'on ait un rapport entre le poids combiné de solides polymères et le poids combiné de constituants pouvant réagir avec l'eau de 0,5:1 à 10:1, de préférence de 1:1 à 4:1. La quantité de polymère organique dispersible (III) par rapport à (I) est telle que l'on obtienne un rapport entre le poids combiné de polymères et le poids combiné de constituants pouvant réagir avec l'eau de 0,5:1 à 10:1, de préférence de 1:1 à 4:1.
