HARDENING ACCELERATOR COMPOSITION CONTAINING DISPERSANTS |
| 摘要 |
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 effected in the present of a water-soluble dispersant having at least one polyalkyleneglycol structural unit with a functional group at one end of the polyalkyleneglycol, being able to interact as an anchor group with the surface of cement particles, the hardening accelerator composition and its use. |

1. A process for the preparation of a hardening accelerator composition comprising reacting a calcium compound with a silicon dioxide containing component under alkaline conditions, wherein the reaction is carried out in the presence of an aqueous solution of a water-soluble dispersant comprising at least one polyalkyleneglycol structural unit with a functional group at one end of the polyalkyleneglycol, said functional group capable of interacting as an anchor group with the surface of cement particles. |
