dc.description.abstract[Abstract]: The thermogalvanic currents between nominally identical segments in a reinforced concrete beam were investigated. Temperature gradients induce galvanic currents that exhibit a 30 0C critical point. The character of the hot electrode side changes from anodic to cathodic when the temperature rises above that pivot point. Parallel tests performed in solution using carbon steel-stainless steel galvanic couples also revealed that 30 0C is a critical temperature. In NaOH solution the carbon steel behaves cathodically with respect to stainless steel but only for T< 30 0C. In Ca(OH)2 solution containing chlorides the carbon steel consistently behaves anodically while the degree of thermogalvanic current exhibits a pronounced temperature dependence.
