This work is a presentation of the PhD thesis "Study of hot dip galvanized rebar corrosion in concrete", performed and presented at the Technical University of Cluj-Napoca by eng. Andreea Hegyi, in June 2011. The work had the following objectives: Study the theoretical aspects of reinforcement corrosion in concrete, in general, and hot dip galvanized reinforcement especially and current state of research knowledge in the field. Study the kinetics and corrosion mechanism of hot dip galvanized steel rebars corrosion in concrete. Identify the hot dip galvanized steel corrosion products and study the influence of the environment on their formation. Study the influence of concrete composition on the hot dip galvanized steel rebars corrosion. Study the influence of hot dip galvanizing on the adherence between the rebar and the concrete matrix as well as the influence of rebars corrosion on the mechanical characteristics of the reinforced concrete. Mathematical modeling of the phenomenon. In this work the chemistry / electrochemical knowledge combine with requirements from the construction sector and fulfill the principles of sustainable development and environment protection.
