Enhanced mechanical and heating performance of multi-walled carbon nanotube-cement composites fabricated using different mixing methods

摘要

To improve the mechanical strength of cement materials used in infrastructure, this study investigates cementitious composites containing multi walled carbon nanotubes (MWCNTs), fabricated using different mixing methods and MWCNT concentrations. A total of 30 MWCNT cementitious composite specimens were fabricated, and the compressive strengths and heating performances of the MWCNT cementitious composites were tested. Mercury intrusion porosimetry tests were conducted to assess porosity decreases in the MWCNT cementitious specimens, and field emission scanning electron microscopy images were obtained to elucidate the internal structures of the composites.
