PROBLEM TO BE SOLVED: To grasp a relation of carbonation depth between measuring points and non-measuring points of carbonation depth.;SOLUTION: A concrete carbonation distribution characteristic acquisition method includes: a carbonation depth acquisition step of acquiring a sequence of carbonation depths which is obtained by measuring carbonation depth of concrete at plural positions linearly for every prescribed interval; a carbonation rate coefficient acquisition step of calculating a sequence of carbonation rate coefficients, from the sequence of carbonation depths; a power spectrum acquisition step of calculating a one-dimensional power spectrum by performing Fourier transform on the sequence of carbonation rate coefficients; a formulation step of obtaining a formula representing the one-dimensional power spectrum; and a formula extension step of extending the formula representing the one-dimensional power spectrum to a formula representing the two-dimensional power spectrum.;COPYRIGHT: (C)2016,JPO&INPIT
