摘要： The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound, said reaction being carried out in the presence of an aqueous solution which contains a water-soluble comb polymer suitable as a plasticizer for hydraulic binders, wherein the water-soluble comb polymer is present as a copolymer which is produced by free radical polymerization in the presence of a phosphorylated monomer and a (meth)acrylic acid ester based polyether macromonomer.

摘要： The present invention relates to an additive for hydraulically setting compositions, comprising a colloidally disperse preparation of at least one salt of a mono- or polyvalent metal cation and of at least one compound which is able to release an anion which forms a low-solubility salt with the metal cation, and of at least one polymeric sulphonated dispersant. The additive is suitable particularly as a slump retainer.

摘要： The present invention relates to an additive for hydraulically setting compositions comprising a colloidally disperse preparation comprising at least one salt of a polyvalent metal cation with at least one organic phosphonate and/or phosphate compound as anion and at least one polymeric dispersant comprising anionic and/or anionogenic groups and polyether side chains. The additive is especially suitable as slump retainer and for improving early strength.

摘要： The present invention relates to cationic copolymers, a process for the production of these cationic copolymers and the use of these cationic copolymers as dispersants for geopolymer binder systems. These cationic copolymers where the cationic charge is due to the presence of certain cyclic and/or polycationic groups are stable towards Hoffmann elimination that would otherwise occur at very high pH values. Moreover, the dispersing effect of cationic polymers can be further enhanced through the addition of polyvalent anions.
