<p>PROBLEM TO BE SOLVED: To provide a material for repairing an acid resistant concrete cross section, which has excellent acid resistance, and has initial strength after hardening and adhesive properties to concrete, and whose strength is hard to be reduced over a long period, and which has excellent operability in an operation site. SOLUTION: The material for repairing the acid resistant concrete cross section is obtained by mixing alumina cement, blast furnace slag fine powder having a Blaine specific surface area of >=3,000 cm<2> /g, short fibers having a fiber length of 3 to 20 mm, classified fly ash having a Blaine specified surface area of >=5,000 cm<2> /g, and a polymer dispersion for admixing cement or a powder resin for emulsifying again.</p> |
