Zusammenfassung:	To provide a cement composition for PC grout capable of achieving a PC grout hardly generating preceding flow or bleeding, and excellent in pumpability.SOLUTION: A cement composition for PC grout contains Portland cement, a cellulose-based thickening agent as an organic thickening agent, and silica fume as an inorganic thickening agent. The cement composition for PC grout satisfies relationships represented by the following Formula (1) to Formula (3). Y=-30X+t (1) 1.0
