Summary:PROBLEM TO BE SOLVED: To provide a material and a method for repairing cross sections which enable the repair of cross sections of concrete structures resulting in an excellent resistance against early age cracking in a short time. SOLUTION: The material for repairing cross sections contains cement, a hardening accelerator, a polymer, basaltic fibers and aggregate. Preferably, the hardening accelerator contains calcium aluminate and gypsum and the basaltic fibers are melt-spun ones. Preferably, 0.1-10 pts.mass of the basaltic fibers are contained in 100 pts.mass of the binder consisting of the cement and the hardening accelerator. The method for repairing cross sections comprises troweling the material for repairing cross sections. COPYRIGHT: (C)2008,JPO&INPIT
