Abstract: AbstractThis study investigated the electrochemical and electronic properties of passive films formed on carbon steel embedded in cement paste compared with those in simulated concrete pore solution. The results showed ...

Abstract: Reinforced concrete structures inevitably experience variable mechanical loads and continuous degradation from aggressive environments such as deicing salts. In this study, several electrochemical measurements were performed ...

Abstract: Specimens were made of ultrahigh-performance concrete (UHPC) with two ratios of sand to cementitious materials, 0.5 and 1.25. Specimens with 0%, 0.5%, 1%, 1.5%, and 2% fiber content were prepared from each mixture. Fiber ...

Abstract: The use of precast concrete elements in the construction of highway bridges has been a common practice in the United States since the 1950s. These bridges have generally performed well during the initial years after ...

Abstract: This study investigated the impact of the grain size of low carbon steel on its electrochemical behavior in a simulated concrete pore solution. Specimens with three grain sizes were used: as-received; coarse, with grains ...

Abstract: This research aimed to apply different models on electrochemical impedance spectroscopy to study the influence of grain refinement and straining obtained from surface mechanical attrition treatment on the passivation of ...

Abstract: Several specimen geometries have been used to assess restrained shrinkage-cracking behavior of concrete materials. This paper used a series of restrained slab tests to illustrate the importance of specimen geometry on the ...
