PROBLEM TO BE SOLVED: To provide a grout material cured object superior in heat resistance, and suitable for a building such as a reinforcement of a concrete structure requiring fire resistant performance. SOLUTION: In this grout material cured object, (I) the peak temperature of a loss tangent (tanδ) in a dynamic viscoelastic spectrum, (II) an average coefficient of linear expansion between 25°C and 50°C, and (III) a compression elastic modulus at 25°C, satisfy the following expressions (1) to (3). Here, in the expressions, (1) 50°C≤(I)≤90°C, (2) (II)≤8.0×10<SP>-6</SP>/°C, and (3) 3,000 MPa≤(III)≤8,000 MPa, are realized. COPYRIGHT: (C)2005,JPO&NCIPI
