The model of carbonated concrete realkalization was compiled on the basis of the multicomponent medium theory equations. The process equations were obtained as a result of an analysis of the partial equations of mass, electric charge, momentum, energy, and entropy inequality. The experimental testing done was related to a theoretical model to determine changes of ion concentrations in a pore solution of the cover, as a result of the realkalization. The pore solution was extracted out of a ground concrete sampled layerwise from specimens and then vacuum concentrated in proportionally to the concrete humidity.
