Thermal Conductivity of foamed concrete
A systematic study of the thermal conductivity of foamed concrete for assorted values of (i) foam content (25%, 50% and 70 %), (ii) water-cement ratio (0.35- 0.55) and (iii) polymer content (5 to 20 % of cementitious material weight) is presented. Experiments were done using a heat flow meter …

The thermal conductivity of intermetallics
The thermal conductivity of titanium aluminide and several ruthenium-aluminium alloys has been studied from room temperature up to 500°C. Ruthenium aluminide is a B2-type intermetallic which is unusual and of special interest because of its toughness, specific strength and stiffness, oxidation …

Thermal conductivity of liquid helium three
We have measured the thermal conductivity of liquid He3 at low pressure from O. 055 0 K to O. 47 o K, at 99.8 psi from O. 0550 K to O. 750 K and at 396.8 psi from O. 0550 K to O. 87 o K. At all pressures and at sufficiently low temperatures the thermal conductivity increases with decreasing …

Thermal conductivity of superconductors below 1K
The thermal conductivity of a metal is dependent on many parameters, and this is particularly true of a superconductor. Only a few of these parameters can be systematically varied in an investigation occupying a finite time. For that reason, this dissertation lays no claim to completness, and as …

Revisiting the theory of alloy thermal conductivity
… years, the PGM has provided great insights into thermal transport in pure homogeneous crystals. However, when one attempts to apply the PGM to understand behavior in non-idealized materials that contain some level of disorder, however, there is growing evidence to suggest that the PGM fails. The …

An automated probe for thermal conductivity measurements
A transient technique was validated for making thermal conductivity measurements. The technique incorporated a small, effectively spherical, heat source and temperature sensing probe. The actual thermal conductivity measurements lasted 30 seconds. After approximately 15 minutes of data reduction, a …
