PROBLEM TO BE SOLVED: To provide a mortar composition excellent in strength-developing ability that can produce at a low cost a mortar hardened body having moderate corrosion resistance (especially, acid resistance) and excellent adhesion, and to provide an acid-proof hydraulic composition from which such a mortar composition can be prepared.SOLUTION: An acid-proof hydraulic composition includes Portland cement, blast furnace slag fine powder, fine aggregate and calcium formate, wherein the blast furnace slag fine powder has a Blaine specific surface area in the range of 2,000-10,000 cm/g and the fine aggregate includes alumina cement clinker aggregate of a maximum particle size of 1.2 mm or less. |
