Different forms and combinations of degradation attacks cause the damage of concrete and reinforced concrete structures. Among the most usual belong ingress of chlorides and carbonation that influence the quality of the concrete and also affect its ability to protect reinforcement. The resistance of concrete against the mentioned attacks is given also by other surrounding conditions, like temperature, mechanical load, etc. In this paper, experimental findings are presented focused on the investigation of the effec...

Durability and reliability of concrete structures is influenced by different forms and combinations of attacks such as environmental, mechanical, chemical and/or electrochemical. Among them the damage due to reinforcement corrosion is a rather crucial one and rather often is governed by the presence of chlorides on the surface of the steel. To assess and/or predict this complex effect causing a specific type of concrete damages, both the experimental and modelling methods have to be utilized. As a part of large ex...

The leading material property of concrete that has the greatest influence on its service life and therefore sustainability depends primarily on the method of loading of the structure and the characteristics of the environment in which it is supposed to fulfill its function. The motivation of this study is the prediction of chloride ingress in time into the concrete specimens using a 1D analytical model implemented in probabilistic software FReET-D. This estimation is directly used for prediction of the time necess...

The structural design of concrete structures needs to result in qualities ensuring structural safety and serviceability, together with durability, robustness, sustainability and resilience. Due to this, the effects of mechanical load, environmental load and even social coherence need to be reflected and included in the formulation of limit states. This is a complex matter involving the time factor, service life, degradation effects, modelling, probability analyses, limit states, costs and other phenomena, and it i...
