20.500.12556/DiRROS-15863 Radiological and physico-chemical characterization of red mud as an Al-containing precursor in inorganic binders for the building industry The potential re-use of red mud in the building and construction industry has been the subject of research of many scientists. The presented research is a contribution to the potential solution of this environmental issue through the synthesis of potential construction materials based on red mud. A promising way of recycling these secondary raw materials is the synthesis of alkali-activated binders or alkali activated materials. Alkali-activated materials or inorganic binders based on red mud are a new class of materials obtained by activation of inorganic precursors mainly constituted by silica, alumina and low content of calcium oxide. Since red mud contains radioactive elements like 226Ra and 232Th, this may be a problem for its further utilization. The content of naturally occurring radionuclides in manufactured material products with potential application in the building and construction industry is important from the standpoint of radiation protection. Gamma radiation of the primordial radionuclides, 40K and members of the uranium and thorium series, increases the external gamma dose rate. However, more and more precedence is being given to limiting the radiological dose originating from building materials on the population these days. The aim of this research was to investigate the possible influence of alkali activation-polymerization processes on the natural radioactivity of alkali activated materials synthesized by red mud (BOKSIT a. d. Milići, Zvornik, Bosnia and Herzegovina) and their structural properties. This research confirmed that during the polymerization process the natural radioactivity was reduced, and that the process of alkali activation of raw materials has an influence on natural radioactivity of synthesized materials. red mud inorganic binder DRIFT natural radioactivity gamma index building industry rdeče blato anorgansko vezivo DRIFT naravna radioaktivnost gama indeks gradbena industrija true false true Vinča Instituta of Nuclear Sciences Angleški jezik Slovenski jezik © the Publisher 2021 Neznano 2022-12-01 10:17:11 2023-05-12 09:49:35 2023-05-13 03:37:07 0000-00-00 00:00:00 2021 0 0 str. 182-191 no. 2 Vol. 36 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-06-01 620.1/.2 1451-3994 10.2298/NTRP2002182K 85748227 1451-39942102182K.pdf 1451-39942102182K.pdf 1 055E06BAC15CA2A63EF12D9B66ABC940 00ef575a16fece8b6df87ebd3c834a33c133933a63b4805c376ccc10d98bd6ac ba1c66b8-7150-11ed-a69a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20981 RAZ_Kljajevic_Ljiljana_2021.pdf RAZ_Kljajevic_Ljiljana_2021.pdf 1 733B0BEEB28107AA90BC8174255BDEA7 831ad1802b63c7d789cb7395f84d2738d9a9255cb6ce6659504057d1d8c69b3c d203b136-9b0a-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21427 Zavod za gradbeništvo Slovenije 0 0 0
