20.500.12556/DiRROS-22557-b66ff1e6-7b67-686f-f41c-8e49abe9ef75 Dataset for the research article “Characterization of steel corrosion in alkali-activated mortars using advanced techniques” Characterization of steel corrosion in alkali-activated mortars using advanced techniques 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. Ta nabor podatkov podpira dolgo-časovne raziskave korozije jekla v alkalijsko-aktiviranih maltah (AAM), ki predstavljajo obetavno alternativo maltam iz običajnega portlandskega cementa (OPC). Vključuje eksperimentalne podatke, zbrane v enem letu izpostavitve, v katerem so bile z jeklom armirane AAM podvržene izmeničnemu močenju in sušenju v raztopini s kloridi. Nabor zajema rezultate za tri različne AAM sestave, pripravljene na osnovi elektrofiltrskega pepela, žlindre in metakaolina. Korozijo smo spremljali z dvema naprednima tehnikama: z mrežo sklopljenih elektrod (ang. coupled multi-electrode array, CMEA) za merjenje delnih tokov ter z električnimi uporovnimi senzorji (ang. electrical resistance sensors, ER) za določanje izgube preseka jekla. Poleg tega nabor podatkov vsebuje slikovne podatke, pridobljene z rentgensko računalniško mikrotomografijo (microCT), ter fotografije jeklene armature po končani izpostavitvi. Ta celovit nabor podatkov predstavlja osnovo za znanstveni članek Characterization of steel corrosion in alkali-activated mortars using advanced techniques (https://doi.org/10.1016/j.cscm.2025.e05165) ter omogoča nadaljnje raziskave korozijskih procesov v AAM materialih in razvoj naprednih pristopov za spremljanje stanja alternativnih cementnih materialov. korozija alkalijsko-aktivirani materiali mreža sklopljenih elektrod električni uporovni senzor rentgenska računalniška mikrotomografija vizualna analiza corrosion alkali‐activated materials coupled multi-electrode array (CMEA) electrical resistance (ER) sensor X-ray computed microtomography (microCT) visual analysis true false false Zavod za gradbeništvo Slovenije Angleški jezik Slovenski jezik © authors, 2025 Neznano 2025-06-04 10:02:28 2025-06-09 07:55:45 2025-10-24 03:51:38 0000-00-00 00:00:00 2025 0 Ljubljana 2025 Ljubljana 1 spletni vir (43 datotek) 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-08-19 54 246394371 ReadMe_AAM_v20-8-2025.txt ReadMe_AAM_v20-8-2025.txt .txt (besedilna) datoteka, ki vsebuje podatke o naboru podatkov.
