摘要： 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.

摘要： A preferably pulverulent dispersing agent comprising as the component having a dispersing action the combination of (a) at least one representative of polycarboxylate ethers with a weight content of from 0.1 to 20%, (b) at least one representative of polycarboxylate esters with a weight content of from 0 to 20% and (c) at least one representative of non-charged copolymers with a weight content of from 0.1 to 20%, which is accessible by co-spray drying the individual components and which is suitable for controlling the flowability of aqueous chemical construction suspensions is claimed. By the dispersing agents which form in situ according to the invention, a controllable subsequent dosing of dispersing agent can be achieved without an additional process step. Furthermore, by subsequent dosing with a flow agent, an increased dosing efficiency of a polymer can be achieved, the extent of the dispersing can be controlled in several stages and the duration of the processability of a fresh mortar can be prolonged especially at elevated temperatures by an increasing saponification.

摘要： The invention relates to the use of an aluminate cement component a) for controlling the rheology of liquid phases based on a clay component b). Preferably, the component a) is made of calcium-aluminate cements and b) clays of the smectite type. The use of component a), which should consist of at least one representative of calcium-aluminate cements in fractions of >= 50 wt.% and which is preferably used for controlling the rheology of water and/or oil based systems, permits a thixotropic thickened product, which is difficult to dilute, to be obtained whose end result can be compared to previously known additives based on, for example, mixed metal oxide/mixed metal hydroxide (MMO/MMH). The use of said invention enables an economical system, which uses a known compound class as an additive, to be produced and the desired effects can be obtained with reduced amounts of additives.
