CuO nanoparticles (CuO-NPs) have been attracted much attention recently as a functional material. This study was conducted to investigate the properties of geopolymer-CuO-NPs as a functional composite. Geopolymer paste was produced through the alkali-activation method of metakaolin. CuO-NPs was synthesized from precipitation of CuSO4 in NaOH solution. The composites were developed by mixing geopolymer with CuO-NPs varying the concentration of CuO-NPs relative to metakaolin. The structure of the raw materials, as well as the resulting composites, was examined by using x-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The mechanical properties of the composites were measured by using compressive and flexural measurements. The measurements results showed that geopolymer CuO-NPs composites offer a wide range of potential structural applications. © 2019 Trans Tech Publications Ltd, Switzerland. All rights reserved.
