Heating Performance of Cementitious Composites with Carbon-Based Nanomaterials

Abstract

Active research has been conducted in recent years on heating construction materials using nanotechnology to solve the problem of black ice, which is often the cause of frequent traffic accidents during winter. To determine the optimal heating construction material, this study analyzed the heating performance of carbon-based nanomaterials, such as multiwalled carbon nanotubes (MWCNTs), conductive carbon black (CB), and graphene nanoplatelets (GNPs). Heating and electrical resistance experiments were performed based on the parameters of the selected nanomaterial, concentrations, and curing days to analyze the heating efficiency. Results showed that compared with OPC, the heating performances of GNP, CB, and MWCNT cementitious composites improved by 132, 171, and 224 times, respectively. Furthermore, the MWCNT cementitious composite exhibited excellent heating efficiency.
