On both sides electronic-mechanical of samples are set appropriately scanner TCS along the selected standards (part of the marked scanned line with meter‘s equipment), depending on the expected thermal conductivity its flat surface and the (TC) to be measured. It is painted strip facing preferable that with one down. measurement the scanning is done simultaneously on the rocks of the same or very similar lithology that are similar to the expected TC. 19 17/11/2017 See more at www.alpine-space.eu/projects/greta Conducting thermal conductivity measurements and processing of their results Operator: Dušan Rajver, MSc During the measurement, the optical head moves under the placed samples along the scanning line, marked on the meter TCS. In the middle of the optical head is the light source of the heat. While scanning, first cool infrared (IR) sensor scans, then the heat source, followed by warm IR sensor. Preparation of parameters following appropriate steps for each measurement is carried out with the TCS program, and the TC measurement itself is computer monitored with this program. Also, the results are processed by this program, for each sample separately. 20 17/11/2017 See more at www.alpine-space.eu/projects/greta ČV-1_a, Črni vrh Shaly siltstone & claystone – 2 T2 Thermal conductivity λ = 1.8 W/(m∙K) 21 17/11/2017 See more at www.alpine-space.eu/projects/greta ČV-1_a, Črni vrh Shaly siltstone & claystone – 2 T2 Thermal conductivity λ = 1.8 W/(m∙K) 22 17/11/2017 See more at www.alpine-space.eu/projects/greta Kc-1_f, Kacan Shaly mudstone – C Thermal conductivity λ = 1.8 W/(m∙K) 23 17/11/2017 See more at www.alpine-space.eu/projects/greta Kc-1_f, Kacan Shaly mudstone – C Thermal conductivity λ = 1.8 W/(m∙K) 24 17/11/2017 See more at www.alpine-space.eu/projects/greta Kc-1_d, Kacan Shaly mudstone – C Thermal conductivity λ = 1.9 W/(m∙K) 25 17/11/2017 See more at www.alpine-space.eu/projects/greta Je-1_a, Jesenica Shaly claystone (amphicline) – 1 T3 Thermal conductivity λ = 1.9 W/(m∙K) (it is mean λ of 2 identical samples) 26 17/11/2017 See more at www.alpine-space.eu/projects/greta St-1_b, Strana Sandstone & finegrained 2 siltstone – (Gröden) P2 Thermal conductivity λ = 2.0 W/(m∙K) (it is mean λ of 2 identical samples) 27 17/11/2017 See more at www.alpine-space.eu/projects/greta St-1_b, Strana (detail) Sandstone & finegrained 2 siltstone – (Gröden) P2 Thermal conductivity λ = 2.0 W/(m∙K) (it is mean λ of 2 identical samples) 28 17/11/2017 See more at www.alpine-space.eu/projects/greta Ra-2_b, Rače Marlstone (heavily tectonized) 5 1 – T1 Thermal conductivity λ = 2.0 W/(m∙K) 29 17/11/2017 See more at www.alpine-space.eu/projects/greta Sv.J-1_b, Sveti Jernej Limestone – P3 Detailed description: Black limestone, in places marly – Žažar beds Thermal conductivity λ = 2.0 W/(m∙K) 30 17/11/2017 See more at www.alpine-space.eu/projects/greta B-1_c (1. large piece), Brdca – at WW2 monument 1 Shaly mudstone – T3 Thermal conductivity λ = 2.0 W/(m∙K) 31 17/11/2017 See more at www.alpine-space.eu/projects/greta Rav, Ravne pri Cerknem 2 Tuff – T2 Thermal conductivity λ =2.3 W/(m∙K) 32 17/11/2017 See more at www.alpine-space.eu/projects/greta ČV-1_b, Črni vrh 2 Tuffitic sandstone – T2 Detailed description (M.
