PROTECTION METHOD OF CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a protection method of a concrete structure which prevents infiltration of water or a corrosive ionic substance through a crack formed on the surface of the concrete structure and enables visible detection of the crack. SOLUTION: On the surface of the concrete structure, a flexible coating film having a crack followability determined according to JSCE-K532-1997 " Method of testing crack followability of surface coating materials" of≥0.50 mm is formed. Then, on the surface of the flexible coating film, a rigid coating film having a followability of≤0.20 mm is formed. COPYRIGHT: (C)2005,JPO&NCIPI
