PROBLEM TO BE SOLVED: To provide an acid-resistant concrete excellent in corrosion resistance and productivity. SOLUTION: This corrosion-resistant concrete contains 100 pts.wt. cement composition containing 5-70% mass (A) alumina cement, 2-40% mass (B) molten slag powder of a CaO/SiO<SB>2</SB>molar ratio of 1.20 or higher, 5-40% mass (in terms of the solids) (C) water glass, 5-60% mass (D) molten slag powder of a CaO/SiO<SB>2</SB>molar ratio of 0.1-1.2 and/or (E) SiO<SB>2</SB>-Al<SB>2</SB>O<SB>3</SB>reactive powder, 5-60% mass reactive siliceous particles of a Blaine specific surface area of 3,000 cm<SP>2</SP>/g or smaller, and 1-30 pts.wt., per 100 pts.wt. solids of the water glass, alcohol and 200-800 pts.wt. aggregate.
