Three types of concrete were investigated during the research programme. Especially, the conducted laboratory tests were focused on chloride ions infiltration into concrete samples whose compositions differed in type of cement. The tests were planned in such a way that the achieved results allowed using a theoretical diffusion model proposed in work [4]. Then, the model was verified by a comparison with the results obtained from the diffusion experiments. Finally, the forecast durability of concrete structures made out of the tested concrete was calculated. The foreseen life-span of the structures was differentiated due to thickness of concrete coating of rebars. The proposed approach enables reliable prediction of durability for the tested types of concrete over time and precise technical life-span of the structure made out of them.
