摘要

[Problems] An object is to provide a gypsum composition, a gypsum slurry, a gypsum hardened body, a gypsum-based building material, a gypsum board, and a manufacturing method for a gypsum-based building material so that it is possible to obtain a gypsum hardened body with a high strength without drastically increasing an amount of added water when a gypsum slurry is provided. [Solving means] A gypsum composition, a gypsum slurry, a gypsum hardened body, a gypsum-based building material, a gypsum board, and a manufacturing method for a gypsum-based building material are provided so that a calcined gypsum and a starch urea phosphate are included.
