Povzetek: This dataset supports the investigation of long-term corrosion behaviour of steel in alkali-activated mortars (AAMs), a promising alternative to ordinary Portland cement (OPC). It contains experimental data collected over a one-year exposure period in which steel-reinforced AAMs were subjected to cyclic wetting and drying with a chloride-containing solution. The dataset includes results from three AAM compositions based on fly ash, slag, and metakaolin. Corrosion monitoring was performed using two advanced techniques: coupled multi-electrode array (CMEA) sensors for measuring partial currents, and electrical resistance (ER) sensors for quantifying steel cross-section loss. Additionally, the dataset contains imaging data from X-ray computed microtomography (microCT), as well as photographs of the steel reinforcement after exposure. This comprehensive dataset provides the foundation for the research paper Characterization of steel corrosion in alkali-activated mortars using advanced techniques (https://doi.org/10.1016/j.cscm.2025.e05165) and enables further studies on corrosion processes in AAMs, supporting the development of advanced monitoring approaches for alternative cementitious materials.
