<P>PROBLEM TO BE SOLVED: To provide a repair method for existing floor which enables shortening of a construction period, deterioration prevention in residual utilization portion by cutting and lower noise while a floor can be repaired to the floor with sufficient performance in terms of strength and durability. <P>SOLUTION: The above-mentioned problem is solved by a repair method for an existing floor 1. In the repair method, after the surface layer of the existing floor 1 formed by a solidification material is removed and a residual utilization part 1B is exposed, a new surface layer 1N is formed on the residual utilization part 1B. At this time, the residual utilization part 1B is coated with a solidification slurry C obtained by mixing a phosphate-based solidification material including phosphate and oxide as a solidification component with water and is hardened to form the new surface layer 1N. <P>COPYRIGHT: (C)2013,JPO&INPIT |
