Tris(1-methylimidazole)zinc(II) triflate as a durability-enhancing ionic admixture for cement composites

The dataset contains source data obtained within the framework of the NCN project 2022/45/B/ST8/02288 entitled “Design of cement composites using sustainable ionic compounds: Evaluation of structural and functional properties,” related to the research results obtained for zinc(II) triflate tris(1-methylimidazole).The presented data concern the characterization of the synthesized ionic liquid as well as the cement composites produced using this compound. The files included in this dataset relate to the tests listed below.Research methodology:The ionic liquid was characterized using UV–Vis spectroscopy (T-9100 UV–Vis spectrophotometer, PEAK Instruments) and X-ray diffraction (XRD; X’Pert PRO MPD X-ray diffractometer, PANalytical). Cement composites were characterized by heat of hydration (according to PN-EN 196-9; TESTING Bluhm & Feuerherdt GmbH), microstructure evaluation (SEM with EDS mapping for Zn presence; Tescan VEGA3 microscope equipped with a QUANTAX EDS system from Bruker), pore structure characterization by mercury intrusion porosimetry (Quantachrome Poremaster 33), shrinkage measurements using the Graf–Kaufman apparatus, and thermal stability of cement composites assessed by TGA–DTG analysis (Jupiter STA 449 F3, Netzsch).
