Item type:Publication, The Effect of the Addition of Construction & Demolition Waste on the Properties of Clay-based Ceramics(Science of Sintering; ISSN: 1820-7413 (online); 0350-820X (print); IF: 1.172 (2019); Published by association for ETRAN Society., 2022-08)Biljana Angjusheva, Vilma Ducman , Emilija FidanchevskiWaste glass and reclaimed brick are types of construction and demolition waste (C&DW) that could potentially be used as secondary raw materials in the production of ceramics. Ceramics based on clay, waste demolished brick (5-15 wt.%) and waste glass (5-20 wt.%) were produced by pressing (P = 68 MPa) and subsequently sintered at 900, 950, 1000, and 1050 o C for one hour. The physical and mechanical properties of the ceramics obtained were evaluated. The addition of demolished brick decreased the density and mechanical properties of the clay specimens and increased the water absorption. The incorporation of waste glass improved the sintering behavior and its mechanical properties. The addition of 20 wt.% waste glass and 10 wt.% waste demolished brick into the clay matrix improved the flexural strength by up to 20.6 % and decreased the water absorption by up to 22 %. The approach presented promotes an opportunity to recycle construction and demolition waste into alternative resource materials, and represents a positive contribution to the environment. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Circular Economy Applied to Metallurgical Waste: Use of Slags and Fly Ash from the Ferronickel Industry in the Production of Eco‑Friendly Composites(Springer, 2022-05-13) ;Perica PaunovikjAnita GrozdanovThe aim of this paper is studying the use of industrial, solid waste materials from the ferro-nickel industry (fly ash – FA, electric furnace slag – EFS and converter slag – CS) as a reinforcing component in new value-added polymer-based composite: eco-friendly, functional geo-membranes. The studied geo-membranes were produced by film-casting method using polyvinyl chloride (PVC) matrix reinforced by the previously mentioned metallurgical waste materials, as-obtained and modified in acid (HCl) and alkaline (NaOH) medium. The study of the produced systems was done through observation and analysis of the effect on their: i) morphology and internal structure (SEM and FTIR analysis), ii) thermal stability (TG/DTA/DTG analysis) and iii) moisture stability (the swelling kinetics was followed and the ultimate rate of swelling after 24 hours was determined). The morphology of the waste materials is of spherical and polygonal non-regular shape. The morphology and microstructural properties of the obtained FA/PVC composites confirmed region of well dispersed particles where the particles were tightly embedded and mechanically interlocked in the PVC matrix indicating strong interfacial interaction with the polymer matrix. All waste materials were thermally stable with minimal 0,8 % weight loss, EFS has been shown as the most stable with weight loss of 0.1% near 350 oC. Generally, all the studied composites have shown a higher swelling degree in comparison with PVC, where the composites reinforced with FA have shown the best performances in adsorption test. - Some of the metrics are blocked by yourconsent settings
