PROBLEM TO BE SOLVED: To provide a method for measuring the deterioration degree of concrete simply and quickly without damaging a concrete structure. SOLUTION: This measuring method of the deterioration degree of the concrete in the concrete structure is characterized as follows: a formwork 4 for a plurality of specimens projecting to the outside is formed on a prescribed spot of a concrete structure formwork 1; the concrete 15 is placed in both formworks 1, 4 to thereby form the specimens 17 integrally with the concrete structure; after the hardening of the concrete 15, only the concrete structure formwork 1 is dismantled; after the elapse of a prescribed period from dismantlement of the concrete structure formwork 1, the specimen formwork 4 is dismantled; and the specimens 17 are split successively every time after the elapse of a prescribed period from the concrete 15 placing, to perform various measurements. After the concrete in the specimen formwork comes to have prescribed compressive strength, the specimen formwork is dismantled. COPYRIGHT: (C)2004,JPO
