Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an admixture for grout and a cement composition for grout. SOLUTION: The admixture for grout contains a water-reducing agent, an expansive admixture, an inorganic fine powder, a viscous agent and a foaming agent. The water-reducing agent of 100 pts.mass contains 40-70 pts.mass of a polycarboxylate-based reducing agent and 60-30 pts.mass of a lignin sulfonate-based reducing agent. The admixture for grout and cement composition for grout using the admixture exhibits the effects of maintaining fluidity for a long period of time, no shrinkage and no bleeding and no separation of the components.
