-11. (canceled)
An aqueous preparation of polymer-modified setting accelerators, comprising:
- a setting accelerator;
- and
- a cationically stabilized polymer which has one or more polymers of ethylenically unsaturated monomers and a polymer having a cationic charge as a cationic protective colloid.
An aqueous concrete composition comprising cement, an aqueous preparation of polymer-modified setting accelerator, and optionally further auxiliaries or additives, wherein the aqueous preparation of the polymer-modified setting accelerator contains a setting accelerator and a cationically stabilized polymer which has one or more polymers of ethylenically unsaturated monomers and a polymer having a cationic charge as a cationic protective colloid.
A process for producing an aqueous concrete composition comprising cement and an aqueous preparation of polymer-modified setting accelerator, the method comprising the steps of:
- mixing cement and optionally further auxiliaries or additives, and
- adding at least one aqueous preparation of a polymer-modified setting accelerator having a setting accelerator and a cationically stabilized polymer which has one or more polymers of ethylenically unsaturated monomers and a polymer having a cationic charge as a cationic protective colloid.
