Abstract: With little information available about the thermal conductivity of sprayed concrete, this article investigates sprayed concrete aging from five hours after casting to 20 days. Thermal conductivity was measured using the Hot Disk transient method. Thermal conductivity was found to be higher at an early age and decreased as the concrete aged. Thermal conductivity is found to have an exponential relationship with density, regardless of mix constituents.
