1. AVALIAÇÃO DO DESEMPENHO DE CONCRETOS COM ADIÇÕES MINERAIS QUANTO À CORROSÃO DAS ARMADURAS INDUZIDA POR CLORETOS / Performance evaluation of concretes content with mineral additions in relation to the reinforcing steels corrosion induced by chlorides
The present work aims to study the performance of concrete with regard to the action of chloride ions, evaluating the influence of both mineral additions and water/binder ratio (w/b), considering kinetic and thermodynamic aspects of the corrosive phenomenon. A experimental research was carried out considering the following variables: the presence of mineral

2. Prediction models of the despassivation of reinforcement steel in concrete structures due to carbonation. / Modelos de previsão da despassivação das armaduras em estruturas de concreto sujeitas à carbonatação.
This work starts presenting the theoretical concepts needed for a good understanding of its contents, including corrosion of steel in concrete, passivation, despassivation, service life and concepts of risk analysis and reliability theory. In chapter three its discussed the several variables that have influence in concrete carbonation, presenting a gener
