Title (EN) DISPERSANT CONTAINING GYPSUM SLURRY
(FR) DISPERSANT CONTENANT UNE BOUILLIE DE GYPSE
Abstract: front page image
(EN)The subject of the present invention is a gypsum containing aqueous slurry containing a phosphate based polycondensate as sole agent with dispersing properties. With a phosphated polycondensate according to the invention as sole dispersing component an improved efficiency was found in comparison with the polycondensates known in the prior art. As additional favorable effect a significantly decreased retardation of the setting and hardening of the various construction compositions and especially of gypsum based slurries compared to other dispersants is to be observed, independently from the dosage of the dispersing component. This effect of the polycondensate component as well as an expedient influence on the pore structure surprisingly can be observed.
(FR)La présente invention a pour objet une bouillie aqueuse à teneur en gypse, contenant un polycondensat à base de phosphate comme unique agent ayant des propriétés dispersantes. Avec un polycondensat phosphaté selon l'invention comme unique composant dispersant, une efficacité améliorée a été trouvée par comparaison avec les polycondensats connus dans l'état de la technique. Comme effet favorable supplémentaire, on observe, indépendamment du dosage du composant dispersant, un retard significativement diminué de la prise et du durcissement des diverses compositions de construction et notamment de bouillies à base de gypse par comparaison avec d'autres dispersants. Cet effet du composant polycondensat ainsi qu'une influence opportune sur la structure des pores peuvent être observés de façon surprenante.
