3.3. Thermal conductivity
Prisms of 200 200 40 mm were cast for thermal conductivity
tests and an Anacon TCA-8 thermal conductivity analyser was
used for k-factor measurements (Fig. 2). The specimens were contacted
by a cold and a hot plate with diameter of 10 cm, which are
kept at temperatures of 37 C and 10 C, respectively. The TCA-8
automatically measures the thickness of the sample and combines
the reading with the heat-flow measurement to yield a direct digital
readout of thermal conductivity [112]. Thermal conductivity
tests were conducted on five series of polystyrene foamed concrete
with densities of 150, 200, 250 and 400 kg/m3, respectively
