PROBLEM TO BE SOLVED: To make a simple and efficient method available for liquefying argillaceous gypsum compositions.SOLUTION: The present invention relates to the use of an additive selected from primary, secondary, and tertiary alkyl amines and quaternary alkyl ammonium compounds to improve a capability of processing an argillaceous gypsum composition comprising comb polymers. The present invention also relates to argillaceous gypsum compositions, dispersing agents, and methods for producing argillaceous gypsum compositions and molded parts that can be produced from the gypsum compositions. 【課題】本発明は、粘土質石膏組成物を液化させるために簡単且つ効率的な方法を利用できるようにする問題に基づいている。【解決手段】本発明は、櫛型ポリマーを含有する粘土質石膏組成物を処理する能力を改善するための第１、第２、及び第３アルキルアミン、並びに第４アルキルアンモニウム化合物から選択される添加剤の使用に関する。本発明はまた、粘土質石膏組成物、分散剤、粘土質石膏組成物、及び石膏組成物から製造できる成形部品を製造するための方法に関する。【選択図】図２
