HYDRAULIC COMPOSITION FOR ADDITIVE MANUFACTURING DEVICE
To provide a hydraulic composition for an additive manufacturing device that can ensure self-standing until the hydraulic composition for the additive manufacturing device is cured, and produce a shaped article with small shrinkage.SOLUTION: A hydraulic composition for an additive manufacturing device includes cement and a lightweight aggregate, and the amount of the lightweight aggregate is 80 to 1,100 pts.mass relative to 100 pts.mass of cement. The lightweight aggregate is preferably an artificial lightweight fine aggregate with an absolute dry density of 2.0 g/cm3 or less and a water absorption rate of 10 to 20%. The hydraulic composition for the additive manufacturing device preferably does not contain an aggregate other than the lightweight aggregate, or contains an aggregate other than the lightweight aggregate in the amount of 50 pts.mass or less per 100 pts.mass of the lightweight aggregate.SELECTED DRAWING: None
【課題】付加製造装置用水硬性組成物が硬化するまでの自立性を確保することができ、かつ、収縮の小さい造形物を製造することができる付加製造装置用水硬性組成物を提供する。【解決手段】セメント及び軽量骨材を含む付加製造装置用水硬性組成物であって、セメント１００質量部に対する軽量骨材の量が、８０～１，１００質量部である付加製造装置用水硬性組成物。軽量骨材は、好ましくは絶乾密度が２．０ｇ／ｃｍ３以下でかつ吸水率が１０～２０％の人工軽量細骨材である。付加製造装置用水硬性組成物は、好ましくは軽量骨材以外の骨材を含まない、または、軽量骨材１００質量部に対して５０質量部以下の量で、軽量骨材以外の骨材を含む。【選択図】なし
