In an effort to lessen the Urban Heat Island effect, aggregate in road wearing course was replaced in varying amounts with sintered clay or recycled ceramic. The physical and thermal properties of these new mixtures were then examined to determine if they showed improvements over traditional wearing course. It was found that the replacement of aggregate with sintered clay decreased the thermal conductivity and thermal diffusivity. A similar result was ...
The authors prepare two series of wood sand concretes by using two types of sand concretes (dune and river) and variable amounts of wood shavings in the mixture. The mechanical and thermal properties of the concretes were then studied, using the transient plane source (TPS) technique. The addition of wood shavings to the sand concrete mix improved the strength of the concretes, and didn't have much of an effect on ...
Through the use of wood shavings as a filler for sand concretes, the authors have been able to improve the thermal properties of the prepared concrete as well as reuse a waste product. The previously used concrete had a higher thermal conductivity and higher density, and through the addition of wood shavings to the concrete mixture, the density and thermal conductivity of the composites have been lowered. The transient plane ...
The authors selected 5 types of softwood species and 5 types of hardwood species that are commonly grown and used for construction in China for thermal analysis. Not only was thermal conductivity measured, but its dependence on moisture content, density and temperature of the wood samples was also investigated. Thermal conductivity was found to increase with increasing density of the wood sample and increasing moisture content. Thermal conductivity was also found to ...
The authors of this article look to use shredded waste tires as a component of a cement composite in order to reuse the discarded material as well as improve the thermal properties of the composite. The TPS method was used in order to determine thermal conductivities of the dry components of the composite, and the auto-coherent homogenisation model was used to determine the thermal conductivity of the rubber/cement/air ...
