<P>PROBLEM TO BE SOLVED: To provide a prediction method of a neutralization depth of concrete subjected to application of a finishing coating material. Ž<P>SOLUTION: A neutralization resistance value R of the finishing coating material is determined from formula (2), by using a thickness d and a CO<SB>2</SB>diffusion coefficient D<SB>f</SB>of the finishing coating material acquired from measurement relative to the finishing coating material, and the neutralization depth x is predicted from formula (1), where A is the neutralization speed coefficient of concrete (known), t is material age, and D<SB>c</SB>is the CO<SB>2</SB>diffusion coefficient of the concrete (known).
