摘要： There is provided a gypsum dispersant and a gypsum additive that improve the fluidity of gypsum slurry even if gypsum raw materials used are different in quality and that do not induce delay of curing of gypsum slurry. A gypsum dispersant, including: (A) a polycarboxylic acid polymer; and (B) a polyamide polyamine obtained by a reaction of a polyalkylene polyamine and a dibasic acid as essential components, and/or an alkylene oxide adduct of the polyamide polyamine.
