It is observed that thermal conductivity increases with increase in time at all moisture contents. The analysis shows that at higher moisture contents (70% and 80% (wb)), thermal conductivity values lie in the range of 0.3027 W/m C to 0.5775 W/m C and 0.3210 W/
m C to 0.6037 W/m C results in increased thermal conductivity. Similarly at lower level moisture contents (50% and 40% (wb)), the thermal conductivity values lie in the range of 0.265 W/m C to 0.5019 W/m C and 0.1526 W/m C to 0.4595 W/m C respectively.
This is due to low density, void spaces present and nonhomogeneity in the sample structure apparently causes the reduction the thermal conductivity.
