The present study investigates the experimental characterization of cementitious materials combined with four different carbon nanofillers; multi walled carbon nanotubes (MWCNTs), carbon nanofibers (CNFs), carbon black (CB) and graphene nanoplatelets (GNPs). Measurements of thermal conductivity and thermal diffusivity were carried out using the Transient Plane Source (TPS) technique. MWCNTs were found to influence thermal conductivity when they were aligned, compared to randomly distributed. GNP paste exhibited the highest thermal conductivity....
The thermophysical properties of natural and artificial samples of marble were investigated to determine how the marble would respond to solar irradiation. The thermal conductivity, specific heat and density were all determined experimentally for the marble samples, and the thermal diffusivity was calculated using these properties. It was determined based on the thermal diffusivity values that heat travelled faster through the natural samples than it did through the artificial samples. ...
When referring to maximizing the energy efficiency of a building, one must first look at the contents of the structure: the make-up of the interior and exterior walls and the contents of the buildings envelope. Generally, when we think of insulation, we think of thermal insulation, which protects us from the blistering, hot days in summer to the dreaded cold days of winter. However, when constructing a building one must ...
