Neutralization processes of concrete are theoreticall modelled for three assumed cases of neutralization mechansims and discussed based upon unsteady state dynamic analysis for the unsteady, diffusion of carbon dioxide in concrete accompanied by carbonation reaction with calcium hydroxide and calcium silicate hydrate, taking into accout of both cases of the constant and increasing concentration of atmospheric carbon dioxide. Influences of various extrinic and intrinsic factors on the progress of the neutralization of concrete are evaluated, using the parabolic law involving constant term derived from this usnsteady state dynamics, which is effective enough to understand and predict almost all the neutralization' processes.
