Abstract

In alkali-activated slags (AAS), where ground granulated blast furnace slag is used as the main precursor, the presence of reduced sulfur species yields a highly reducing pore solution environment. This study investigates the influence of sulfide on steel passivation in alkali-activated slag mortars immersed in alkaline (1 M NaOH) and alkaline chloride-rich (1 M NaOH with 5 M NaCl) solutions, and the dependency of chloride-induced pitting on the immersion time and the concentration of sulfide in simulated alkali-activated slag pore solutions (containing 0.80 M OH- A nd 0 M, 0.01 M and 0.45 M HS-) by means of electrochemical techniques. Surface-sensitive X-ray photoelectron spectroscopic (XPS) and Raman spectroscopic analysis of the corrosion products formed on the steel surfaces, both in alkali-activated slag mortars and in simulated pore solutions, shows that sulfide has a very important influence in altering-but not necessarily in a deleterious way-the characteristics of the steel surface under these conditions.
