PROBLEM TO BE SOLVED: To provide a composition which acts in particular as a hardening accelerator and moreover performs as a plasticizer, for causing aqueous slurries of pulverulent inorganic or organic substances to improve their workability.SOLUTION: The object of the invention is achieved by a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound, the reaction of the water-soluble calcium compound with the water-soluble silicate compound being carried out in the presence of an aqueous solution which contains a water-soluble comb polymer suitable as a plasticizer for hydraulic binders.SELECTED DRAWING: None 【課題】粉状の無機または有機質の水性スラリーに、作業性を向上させるために、とりわけ硬化促進剤として作用し、さらに可塑剤として機能する組成物の提供。【解決手段】水溶性カルシウム化合物と水溶性ケイ酸塩化合物との反応による硬化促進剤組成物の製造方法であって、水溶性カルシウム化合物と水溶性ケイ酸塩化合物との反応が、水硬性結合剤のための可塑剤として好適な水溶性櫛形ポリマーを含有する水溶液の存在下で実施される方法によって達成される。【選択図】なし
