(57) Abstract: A liquid containing (A) a fast-setting cement, (B) gypsum, and (C) a polycarboxylic acid-based polymer compound having a polyalkylene glycol chain as a main component is prepared by adding a reducing inorganic A fast-curing grout composition containing a powdery cement dispersant obtained by adding a compound and a reducing organic compound, followed by drying and powdering. The quick-setting grout composition of the present invention can maintain a high filling property and separation resistance for a long period of time as compared with conventionally used quick-setting grout compositions, and thus has a complicated structure. It can be applied to the body, and the construction period can be shortened due to its excellent quick-setting properties. |
