20.500.12556/DiRROS-17381 Pilot production of façade panels variability of mix design As part of the WOOL2LOOP project, the Slovenian National Building and Civil Engineering Institute (ZAG), in collaboration with Termit d.d. were responsible for the production of façade panels. An initial mix design was developed at ZAG, where alkali-activated façade panels were produced, primarily from stone wool waste, while production took place at Termit. The mix design was changed twice during the pilot production, before a final product with suitable durability was developed. A compressive strength of up to 60 MPa and bending strength of approximately 20 MPa was achieved. The mechanical properties, however, varied, due to the unevenly milled batches of the milled mineral wool. Milling on a larger scale is very challenging, and it is difficult to obtain consistent quality of the milled material. Once the correct curing process had been found, however, the panels produced showed good performance. Moreover, the results from leaching tests showed that the elevated concentrations of certain elements (Cr, As and Mo) did not exceed the legal limits for non- hazardous waste. waste mineral wool alkali activated material façade panels pilot production circular economy odpadna mineralna volna alkalijsko aktivirani materiali fasadne plošče pilotna proizvodnja krožna ekonomija true false true University of Maribor, University Press, Faculty of Chemistry and Chemical Engineering Angleški jezik Slovenski jezik © Authors & Potrč, Bogataj, Kravanja, Novak Pintarič, 2023 Neznano 2023-11-28 15:09:24 2023-11-28 15:09:24 2023-11-29 03:38:02 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 2. 2. 2023; Str. 25-43 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-01-30 620.1/.2 140435971 139091459 https://doi.org/10.18690/um.fkkt.1.2023 1 5ab5e3f9-8def-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23605 RAZ_Pavlin_Majda_2023.pdf RAZ_Pavlin_Majda_2023.pdf 1 65E1559B03C8D8F6052385B033DF04C2 ec2cf3ad85015bff7a790e7bebca7d2d19ade3ef6949b1fb40377759a441e178 8b28f3d6-8df0-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23606 Zavod za gradbeništvo Slovenije 0 0 0
