To provide a rapid hardening mortar composition having flowability immediately after preparation, having softness to be extruded from a 3D printer nozzle and capable of self-support after extrusion, and not to be crushed or broken even when a material is laminated thereon within 10 minutes.SOLUTION: A rapid hardening mortar composition includes a hydraulic cement, aggregates, water, and amorphous aluminum hydroxide, wherein the rapid hardening mortar composition has a flow value before impact, measured for the rapid hardening mortar composition immediately after preparation by a flow test regulated by JIS R5201:2015, of 100-120 mm, and a flow value after the impact of 135-250 mm.SELECTED DRAWING: None
【課題】調製直後は流動性があり、３Ｄプリンターのノズルから押し出しできる柔らかさを有し、且つ、押し出し後は自立可能で、１０分以内で上に材料が積層されても、潰壊したり崩壊したりすることのない速硬性モルタル組成物を提供する。【解決手段】水硬性セメントと骨材と水と非晶質水酸化アルミニウムとを含む速硬性モルタル組成物であって、調製直後の該速硬性モルタル組成物についてＪＩＳ Ｒ５２０１：２０１５に規定するフロー試験で測定した打撃前のフロー値が１００～１２０ｍｍであり、同打撃後のフロー値が１３５～２５０ｍｍである速硬性モルタル組成物。【選択図】なし
