Abstract

[Problem] To provide a gypsum dispersant and a gypsum additive that have an excellent improvement effect on the fluidity of a gypsum slurry even if raw gypsums of varying qualities are used and that do not delay curing of the gypsum slurry. [Solution] This gypsum dispersant is characterized by containing: (A) a polycarboxylic acid polymer; and (B) a polyamide polyamine and/or an alkylene oxide adduct thereof obtained by reacting a polyalkylene polyamine and a dibasic acid as essential components.
