The purpose of this study is to evaluate the major influence of multiwall carbon nanotubes (MWCNTs) on the thermal conductivity of alkali-activated engineered geopolymer composites (AAEGCs). In order to serve the purpose, six ambient cured AAEGC mixes consisting of two types of powder-based activators, three (0, 3, and 6%) different contents of MWCNT, binary combinations (45% of ground granulated blast furnace slag and 55% of Class C fly ash) of industrial waste-based source materials, silica sand, and polyvinyl alcohol (PVA) fiber were developed using “one-part mix” technique. The impact of the combination of source materials, activators, and MWCNT dosages on the thermal properties of AAEGCS is evaluated and discussed based on temperature–time history, conductivity, and resistivity of concrete. The finding of the study showed that, during the thermal conductivity test, the AAEGC mixes’ temperature change increased when the MWCNT content of the mixes was increased from 0 to 0.6%. The thermal conductivity and diffusivity of AAEGC mixes increased with MWCNT dosages from 0% to 0.6%. Thermal conductivity of AAEGCs containing 0.3% and 0.6% MWCNT enhanced nearly 16% and 30% (for mixes with low calcium reagent type 1) and 18% and 46% (for mixes with high calcium reagent type 2), respectively.
