PURPOSE:To produce the titled self-leveling material having long usable time and improving workability by specifying hemihydrate gypsum content of cement in the cement self-leveling material combined additive and aggregate with cement. CONSTITUTION:When the cement self-leveling material is formed by combining additive and aggregate with cement as base material, hemihydrate gypsum content of the gypsum (dihydrate, hemihydrate, II-type anhydride, etc.) in the cement is specified in <1.5wt.% as SO3. Various kinds of cement can be used as the cement and, as the additive, viscosity regulating agent, fluidizing agent, accelerator, antifoaming agent, etc., are exemplified. As a result, the cement self-leveling material having high level accuracy is obtd.
