This study examines the influence of multiwalled carbon nanotubes (MWCNTs) on cementitious composites, specifically focusing fabrication multifunctional composites known as ultrahigh-performance (UHPC) composites. Key properties such compressive strength, thermal performance, and electrical resistance were examined with varying MWCNT contents, curing methods, duration, supply voltage. The effects incorporation MWCNTs hydration reactions analyzed using field-emission scanning electron microscopy, thermogravimetric analysis, X-ray diffraction. revealed that UHPC can achieve a maximum ultrahigh strength 120.8 MPa. Additionally, enabled to reach surface temperature 90.6 °C during heating. Furthermore, power consumption was found be predictable based type duration curing. Notably, in remained unaffected by content. findings emphasize potential offering exceptional heating capabilities, performance construction materials.
