The present invention provides a three-dimensional modeling cementitious material for construction that can provide excellent self-sustainability and strength development, and a three-dimensional modeling method for construction. The mass ratio of cement, (A) aggregate, (B) lignin sulfonic acid dispersant (R) and melamine sulfonic acid dispersant (M) is R: M = 100: 80-400. Dispersant, (C) thickener, (D) setting retarder, (E) amorphous calcium aluminosilicate containing 10-25% SiO 2 in terms of oxide, (F) gypsum, and (G) short Adopt a cement material for 3D modeling for construction that contains fiber.
