To provide a grout admixture and a PC grout admixture in which excellent flowability and excellent material separation resistance are obtained even if cements are different, and to provide a grout material and a PC grout in which excellent flowability and excellent material separation resistance can be stably obtained.
The subject can be solved by including: a thickener; an inflation material; and two or more sorts of short time type water reducing agents. The short time type water reducing agent is suitably a polycarboxylic acid based water reducing agent. Moreover, the short time type water reducing agent is suitably a short-time stable type water reducing agent and a short-time reducing type water reducing agent, and especially a short-time stable type polycarboxylic acid based water reducing agent and a short-time reducing type polycarboxylic acid based water reducing agent.
