Deicing and anti-icing performance of an innovative polyurethane pavement surface layer that replaces asphalt binder was studied. Thermal properties of polyurethane concrete and asphalt concrete were measured using a Thermal Constants Analyzer with transient plane source (TPS) method. Results found that polyurethane concrete had similar thermal conductivity to asphalt concrete, but a much greater specific heat. Polyurethane was also found to have a better anti-icing and deicing performance compared to ...
Thermal conductivity of 47 pairs of granitic rock specimens were measured using the Transient Plane Source (TPS) method. Crystalline rocks are being considered for the construction high-level radioactive waste (HLW) disposal systems. Dry and wet samples, the effect of water saturation, and the influence of temperature were all factors investigated in this study....
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. 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....
The expanding production of polymeric materials is causing plastic waste to become a growing concern. This study aimed to fabricate cement and mortar composites that contained plastic in an attempt to extend the life of non-reusable plastics. The thermal conductivity of the composite material was measured using the transient plane source (TPS) technique. Results showed that as expected, thermal conductivity decreased as the plastic content in cement and mortar composites ...
Ice surfaces dictate energy usage in skating rinks because they are the largest heat exchangers in the building. This study aimed to improve the concrete material used in ice rinks to maximize the performance of their refrigeration systems. The TPS method measured the thermal conductivity and thermal diffusivity of the improved concrete using the Transient Plane Source (TPS) method. Results indicated that adding iron ore to the concrete might improve ...
