Abstract
The purpose of this study develops eco-friendly, cost-effective fly ash-based cement mortar with low dosages of carbon. In this experiment, 0.005% of Functionalized Carbon Nanotubes (FCNTs) were incorporated in High Volume Fly-ash (HVFA) based cement mortar to improve the mechanical strength and electrical resistivity properties. Compressive and split tensile strength has been increased by 8.75% and 24.19% at the curing age of 90 days, respectively, compared to the control sample (HVFA-C). Moreover, the improved electrical resistivity was 61.16 k-om-cm for HVFA-FCNTs compared to HVFA-C i.e., 11.15 k-om-cm. Additionally, the synthesized FCNTs were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscope (FE-SEM), and X-Ray diffractometer (XRD). The crystalline behavior and functionalities of HVFA cement mortar were characterized using XRD and FTIR.
