  • Valorisation of fly ash as secondary raw material towards implementation of circular economy [Elektronski vir]
    Angjusheva, Biljana ...
    Industrial waste like metallurgical slags, fly and bottom ashes, red mud, mine residues represent potential secondary raw materials which could be used in the production of a variety construction ... products such as cement, concrete, bricks, glass-ceramics etc. Currently, huge amounts of these residues have low recycling rate or are landfilled, especially in East & South-East Europe region. Based on the aims of circular economy these industrial wastes from one industry could be treated as raw material resources for other industry. One of the ways of recycling these materials is synthesis of mineral binders with high Alcontent which can be further used as eco-friendly binders. The high Al content presents the main goal for synthesis of innovative Al-rich binders, since it is mainly used from natural valuable resource - bauxite. The replacement of bauxite with Al-rich residues presents the challenge in the synthesis of innovative binders and this is the main challenge in RIS-ALiCE project in the frame of EIT Raw materials Programme. Characterization of fly ash (as received and mechanically activated) from materials point (chemical and mineralogical composition, morphology of particles, granulometric composition) and radiological point (radionuclides Ra-226, Th-232, K-40 concentration) will be present in this study and its potentiality for synthesis innovative binders will be discussed.
