Title:
DISPERSANT CONTAINING GYPSUM SLURRY
Document Type and Number:
WIPO Patent Application WO/2012/049077
Kind Code:
A3
Abstract:
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.
