摘要: The invention concerns a process for the preparation of hardening accelerator composition by reaction water-soluble calcium compound with silicate compound, being carried out in presence an aqueous solution which contains plasticizer suitable hydraulic binders, characterized that said is apatite and molar ratio to phosphor from25/1to 400/1.
