20.500.12556/DiRROS-15831 Preparation of façade panels based on alkali-activated waste mineral wool, their characterization and durability aspects Mineral wool is a widely used insulation material and one of the largest components of construction and demolition waste, yet it mainly ends up in landfills. In this work, we explored the potential recycling of waste stone wool in the pilot production of alkali-activated façade panels. The current work shows mechanical properties, SEM-EDS and mercury intrusion porosimetry analyses for three different mix designs used for the preparation of façade panels. They are all composed of waste stone wool and differ in the amount of co-binders (local slag, lime, metakaolin and/or fly ash) selected by the preliminary studies. In this study, co-binders were added to increase early strength and improve the mechanical properties and freeze-thaw resistance. The mechanical properties of each were measured up to 256 days, different durability tests were executed, and, by evaluating the mechanical properties, microstructure and workability of the mortar, the most suitable mix was selected to be used for pilot production. In addition, the leaching test of the selected mixture showed no exceeded toxic trace elements and therefore got classified as non-hazardous waste after its use. alkali activation waste mineral wool SEM XRF XRD mechanical strength alkalijska aktivacija odpadna volna SEM XRF XRD mehanska trdnost odlagališče jeklarske žlindre true false true John Wiley & Sons, Ltd Angleški jezik Slovenski jezik © 2022 The Authors.International Journal of Applied Ceramic Technologypublished by Wiley Periodicals LLC on behalf of American Ceramics Society Neznano 2022-11-23 12:24:38 2023-06-19 06:26:10 2024-08-06 09:18:56 0000-00-00 00:00:00 2022 0 0 Nasl. z nasl. zaslona; Opis vira z dne 7. 1. 2022; str. 1227-1234 issue 3 Vol. 19 May 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-01-05 620.1/.2 1744-7402 10.1111/ijac.13998 92496131 https://ceramics.onlinelibrary.wiley.com/doi/10.1111/ijac.13998 1 17227485-6b19-11ed-a69a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20940 RAZ_Pavlin_Majda_2022.pdf RAZ_Pavlin_Majda_2022.pdf 1 5A033FB27F8B33C72648D4DCD12698E6 c29f4b16496c6e5d1d68b0d212504cdcb9fe19441a28ee67a927d8787ae378d3 00f01a81-8b4b-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21198 Zavod za gradbeništvo Slovenije 0 0 0
