20.500.12556/DiRROS-17625 Influence of homogenization of alkali-activated slurry on mechanical strength Alkali-activated materials are promising materials for the construction industry due to the accessibility of the precursors, which are mainly secondary industrial by-products, and their cost- effective and energy-efficient production. Although these materials are not new, some of the parameters in the technological process are not yet fully understood and tested. Therefore, in this paper in the means of mechanical strength, the preparation of alkali-activated pastes by using a three-roll mill homogenization method is discussed. The influence of homogenization of alkali- activated slurry has been evaluated on different waste materials (fly ash, fly ash with metakaolin, slag mixture (electric arc furnace slag and ladle slag), glass wool, waste green ceramics), which are treated with different alkali activators (NaOH, commercial sodium silicate solution, laboratory-produced alkali activators based on waste cathode- ray tube glass) with different curing regimes (60 °C and 70 °C) and different drying methods (drying at room temperature, drying at 105 °C). The viscosity of the slurry before homogenization was higher than after homogenization, the distribution of elements was more uniform and the compressive strength higher in all homogenized alkali activated materials, regardless of other parameters. secondary raw material alkali activated material foaming homogenization mechanical strength sekundarne surovine alkalijsko aktivirani materiali penjenje homogenizacija tlačna trdnost true false true University of Maribor, University Press, Faculty of Chemistry and Chemical Engineering Angleški jezik Slovenski jezik © Authors & Potrč, Bogataj, Kravanja, Novak Pintarič, 2022 Neznano 2023-12-21 08:42:26 2023-12-21 08:42:26 2023-12-24 03:36:13 0000-00-00 00:00:00 2022 0 0 Nasl. z nasl. zaslona; Opis vira z dne 9. 6. 2022; Str. 11-49 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-05-30 620.1/.2 10.18690/um.fkkt.2.2022.9 111161347 109396739 RAZ_Horvat_Barbara_2022.pdf RAZ_Horvat_Barbara_2022.pdf 1 D5B3FF3FA17EAB1148C5DC25906BCDE9 e0e79114d5dc82d60f8ac181525bbc1e6415325e023d1250c488bc62beb73a79 229c5d46-9fcd-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23952 https://press.um.si/index.php/ump/catalog/book/677 0 29d8d518-9fcd-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23953 Zavod za gradbeništvo Slovenije 0 0 0
