(57) [Summary] [Objective] The present invention has high fluidity and its excellent holding ability, and therefore has a long pot life in accordance with the actual situation, and at the same time has a small setting retardation property, Therefore, it is possible to obtain a high-quality cured product that has a fast setting and curing time according to the actual situation and has very few initial cracks. The present invention provides a self-leveling cement aqueous composition. [Structure] The present invention comprises 1 to 20 parts by weight of an expanding agent, 7 parts by weight or less of a water retention agent, 2 parts by weight or less of an antifoaming agent, 30 to 300 parts by weight of an aggregate, and 100 to 100 parts by weight of cement, and water. Is 25 ~ A self-leveling cement aqueous composition in which 100 parts by weight and a dispersant of 0.05 to 2.0 parts by weight are blended, wherein the dispersant has amide groups in the molecule α, β. A specific graft copolymer obtained by grafting a polymer block obtained by radically polymerizing an unsaturated monomer. |
