Properties of inorganic polymers based on ground waste concrete containing CuO and ZnO nanoparticlesProperties of inorganic polymers based on ground waste concrete containing CuO and ZnO nanoparticles Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2023-04-102021enA.I.V. would like to acknowledge financial support of this work by the project “INVALOR: Research Infrastructure for Waste Valorization and Sustainable Management” (MIS 5002495) which is implemented under the Action “Reinforcement of the Research and Innovation Infrastructure”, funded by the Operational Programme “Competitiveness, Entrepreneurship and Innovation” (NSRF 2014–2020) and co-financed by Greece and the European Union (European Regional Development Fund).The effect of copper oxide and zinc oxide nanoparticles (NPs) on the mechanical and thermal properties of ground waste concrete inorganic polymers (GWC IPs) has been investigated. NPs are added to GWC IPs at loadings of 0.1, 0.5, 1, and 2% w/w. The phase composition and microstructure of NPs GWC IPs have also been examined using X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscope (SEM/EDS) techniques. Results show that the mechanical properties of GWC IPs are improved (23 MPa) due to addition of NPs (1% ZnO). In particular, GWC IPs embedded with 0.5% CuO and 1% ZnO NPs exhibited relatively improved compressive strength. The addition of NPs decreases the macroporosity and increases the mesoporosity of IPs matrix and decreases relatively the ability of IPs matrix to water absorption. The antimicrobial activity of GWC IPs doped with 0.5 and 1% CuO NPs against E. coli was also determined.http://creativecommons.org/licenses/by/4.0/Polymers1317Vavouraki_et_al_Polymers_13(17)_2021.pdfChania [Greece]Library of TUC2023-04-10application/pdf15.0 MBfree Vavouraki Aikaterini Βαβουρακη Αικατερινη Gounaki Iosifina Γουνακη Ιωσηφινα Venieri Danai Βενιερη Δαναη MDPI Inorganic polymers Ground waste concrete Nanoparticles Copper oxide Zinc oxide Antibacterial activity
