Abstract
ABSTRACT The additive for concrete strengthening purposes based on the multiwalled carbon nanotubes was sonochemically synthesised under mild conditions through a radical polymerisation route by the reaction of oxidised nanotubes with maleic anhydride and α-nonene monomers. The Catalytic Chemical Vapour Deposition over the Fe-Co/Al2O3 catalyst was the method for the synthesis of the nanotubes used as the main reinforcement part. The resulting nanocomposite was characterised using Transmission electron microscopy, Scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy techniques. The results from the above-mentioned methods revealed the success of the synthesis process. The mechanical testing showed that the obtained nanostructure is suitable additive material for concrete strengthening purposes with about 52.2% strengthening potential.
