摘要:
The present invention relates to a process for producing solid compositions comprising calcium silicate hydrate and at least one water-soluble polymer with cationic structural units, uncharged structural units and/or anionic structural units containing sulpho groups, wherein an aqueous suspension of the calcium silicate hydrate is contacted with the polymer and the mixture is dried by a drum drying process./
摘要:
Suggested is a novel coated particle of active ingredients with controlled release properties at pH-values from 10 to 14, wherein the active ingredient is selected from one or more construction chemical additives for the control of inorganic binders, characterized in that the coating comprises shellac, a process for its manufacture and the use thereof as an additive for mortars, dry mortars, cement slurries and/or concretes.

摘要:
The invention concerns a solid composition comprising calcium silicate hydrate and at least one water-soluble cationic (co)polymer. Additionally, a process for producing the compositions, in which an aqueous suspension of calcium silicate hydrate, preferably suitable as a setting and curing accelerator for (portland)cement-containing binder systems, is contacted with at least one cationic (co)polymer and the product is dried. Also concerned is the use as setting accelerator in preferably (portland)cement-containing building material mixtures and as grinding assistant in the production of (portland) cement. The invention further concerned building material mixtures comprising the solid compositions of the invention.
