Abstract

Abstract

To investigate the reinforcing effect and mechanism of multi-walled carbon nanotubes on volcanic ash-based geopolymer, the numbers and areas of aggregates of multi-walled carbon nanotubes dispersions at different ultrasonic times were compared by using microscopy and image recognition, and an appropriate ultrasonic dispersion time was determined. Geopolymers were prepared by mixing the dispersion, alkaline activator solution, and volcanic ash in different orders. The effects of different types and concentrations of multi-walled carbon nanotubes on the workability and mechanical properties of the geopolymer were investigated by the consistency test of the slurry and the three-point bending test and the uniaxial compression test of hardened specimens. The micro-morphologies and pore structures of the geopolymer products were characterized by scanning electron microscope-energy dispersive spectrometer and mercury intrusion porosimetry. Analysis results show that the dispersion effect of multi-walled carbon nanotubes improves with the increase of ultrasonic time. After 45 min ultrasonication, the areas of more than 85% aggregates decrease to 0-100 μm², the total ratio of the aggregate areas is less than 1%, and the average area is less than 50 μm². The order of adding multi-walled carbon nanotube dispersion before adding NaOH solution is more favorable for the uniform dispersion of fibers and the preservation of the geopolymer workability. At a mass content of 0.10%, the multi-walled carbon nanotubes have little effect on the flowability of volcanic ash-based geopolymer and can effectively enhance the mechanical properties. The functionalized multi-walled carbon nanotubes have stronger hydrophilicity and wettability, leading to a slighter impact on the workability of the slurry and a more significant improvement in the mechanical properties of the hardened specimens. The 28 d flexural and compressive strengths can increase by up to 31.0% and 15.9%, respectively, compared with the reference group. The microscopic test results show that multi-walled carbon nanotubes play bridging, filling, and nucleation roles in the geopolymer, thus achieving the improvement of the performance.
