PROBLEM TO BE SOLVED: To accurately estimate a zone of reduced compressive strength in a depth direction of a concrete structure without having to sample a large number of cores from the concrete structure.;SOLUTION: A method of estimating a zone of reduced compressive strength in a depth direction of a concrete structure includes: a first core sampling step for sampling a core for rebound hardness measurement along a depth direction of the concrete structure; a rebound hardness measurement step for measuring the rebound hardness using an echotip hardness tester at each point in the depth direction of the core sampled for rebound hardness measurement; and an estimation step for estimating a zone of reduced compressive strength in the depth direction of the concrete structure based on distribution of the measured rebound hardness.;COPYRIGHT: (C)2014,JPO&INPIT
