20.500.12556/DiRROS-16243 Technical and radiological characterisation of fly ash and bottom ash from thermal power plant Huge quantities of fly ash and bottom ash are generated from thermal power plants and it presents great concern for country, mainly due to the environmental effects. In this study, fly ashes and bottom ash were characterized from technical and radiological aspects. Health effect due to the activity of radionuclides 226Ra, 232Th and 40K was estimated via radium equivalent activity (Raeq), external hazards index (Hex), the external absorbed dose rate (D) and annual effective dose rate (EDR). The specific surface area (40.25 m2 g−1), particle density (1.88 g cm−3) and LOI (23.49%) were typical for bottom ash. Siliceous fly ash contained 32% reactive silica. The annual effective dose rate for all ashes is ≤ 0.2 mSv y−1. Both, fly ash and bottom ash present potential secondary raw materials to be used for building purposes as result of their technological and radiological assessment. fly ash bottom ash gamma spectrometry building materials elektrofiltrski pepel pepel z rešetk gama spektroskopija gradbeni materiali true false true Elsevier, Akadémiai K Angleški jezik Slovenski jezik © The Author(s) 2021 Neznano 2023-02-10 12:19:55 2023-05-22 09:27:04 2024-04-18 14:20:36 0000-00-00 00:00:00 2021 0 0 str. 685-694 Iss. 3 Vol. 330 Sept. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-09-18 620.1/.2 0236-5731 10.1007/s10967-021-07980-w 78227203 https://link.springer.com/article/10.1007%2Fs10967-021-07980-w 1 d9ecab88-a934-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21648 RAZ_Fidanchevski_Emilija_2021.pdf RAZ_Fidanchevski_Emilija_2021.pdf 1 7E371BC6CDB51771A08CCF1D6D86F931 c48f067e708fdcc444076ef0abe92a02f74ef996a199cfbc485e3ccb60738ac9 b20ebb7c-a935-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21649 Zavod za gradbeništvo Slovenije 0 0 0
