Zusammenfassung:PROBLEM TO BE SOLVED: To provide a grout composition which achieves, at a sufficiently high level, workability, suppression property of material separation and filling property into gaps, and which give a hardened body which is excellent in sulfuric acid resistance.SOLUTION: A sulfuric acid-resistant grout composition includes 100 pts.mass of cement; 0.3-5 pts.mass of a naphthalene sulfonate condensation product whose number average molecular weight is 2,000-6,000 and whose weight average molecular weight is 3,000-30,000, on a solid basis; 5-20 pts.mass of an inflating material; 0.1-0.8 pt.mass of a foaming material; and fine aggregate.
