Description

This lecture covers the mechanisms of concrete degradation, including reinforcement corrosion due to chlorides and carbonation. It explains diffusion phenomena in concrete, laboratory tests for corrosion, and preventive measures such as controlling chloride exposure. The instructor discusses the impact of freeze-thaw cycles, alkali granulate reaction, and acid attacks on concrete structures, emphasizing the importance of material-environment interaction. Various exposure classes according to standards are detailed, along with diagnosis and repair techniques for corroded structures. The lecture highlights the significance of concrete quality, porosity effects, and the role of cement paste in enhancing durability.
