CEMENT COMPOSITION FOR MOLDING
To provide a cement composition for molding which is a composition for molding manufacture obtained through mixing of a cement composition for molding and water, and which has adequate flowability immediately after preparation, can maintain flowability for a long period of time, prevents collapse of a shape of the composition for molding manufacture immediately after molding during molding using a nozzle in an additive manufacture technique, is excellent in quick curability of the composition for molding manufacture, and accordingly can obtain a molding which prevents collapse of a shape of a molding when the composition for molding manufacture is laminated and is excellent in dimension stability.SOLUTION: A cement composition for molding contains cement, calcium aluminates, a fiber and a setting retarder. An amount of the calcium aluminates is 50-80 pts.mass, an amount of the fiber is 0.3-4.8 pts.mass, and an amount of the setting retarder is 0.1-5 pts.mass, with respect to 100 pts.mass of the total of the cement.SELECTED DRAWING: None
【課題】造形用セメント組成物と水を混合してなる造形物製造用組成物を、調製直後に適度の流動性を有し、かつ、該流動性を長時間維持しうるものにすることができ、付加製造技術においてノズル等を用いて造形を行う際に、造形物製造用組成物の造形直後の形状が崩れることがなく、かつ、造形物製造用組成物が速硬性に優れることから、造形物製造用組成物を積層しても、造形物の形状が崩れず、更には、寸法安定性に優れた造形物を得ることができる造形用セメント組成物を提供する。【解決手段】セメント、カルシウムアルミネート類、繊維、及び凝結遅延剤を含む造形用セメント組成物であって、上記セメント１００質量部に対して、上記カルシウムアルミネート類の量が５０〜８０質量部であり、上記繊維の量が０．３〜４．８質量部であり、上記凝結遅延剤の量が０．１〜５質量部である造形用セメント組成物。【選択図】なし
