The article presents the experimental and theoretical research of reinforced concrete beams deformations, damaged in the conditions of simultaneous influence of aggressive environment and loading with their further renewal. The peculiarity of this research is that during influence of aggressive environment reinforced-concrete beams were tested both under the action of loading and without it. The influence of aggressive environment and renewal took place in the conditions of the operating loading on the reinforced-concrete beams. Such a combination of influences allows to define the optimal method of research of the renewal process in reinforced-concrete structures and the influence of loading, at which the strengthening takes place on the efficiency of renewal and deformations of experimental samples. The experimental and theoretical values of deformations of reinforced-concrete beams which were renewed without loading and under the operating loading are obtained. Their comparison is carried out with the purpose of determining the optimal method of research of such structures.
