Abstract
Recently, the occurrence of freezing accidents in the winter has increased, as subzero temperatures have decreased rapidly. Several studies have been conducted on the prevention of freezing accidents in the winter. In this study, the heating and electrical performance of nano-sidewalk blocks mixed with multiwalled carbon nanotubes (MWCNTs) were evaluated. The parameters were the curing duration, MWCNT concentration, and supply voltage. The size of the interlocking block specimen was 200 mm × 100 mm × 60 mm. The heating performance of the specimens increased by 12.3 times, with an increase in the MWCNT concentration and supply voltage.
