Abstract: Perlite was added to mortar in order to determine if the resulting composite was more thermally insulating than conventional shotcrete. This study was conducted to determine if shotcrete in which sand has been replaced by perlite can potentially be used as thermal insulation for underground mines. It was found that the addition of perlite decreased the weight of the shotcrete, as well as the thermal conductivity and diffusivity, but decreased its mechanical strength.
