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 …

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 …
