Infiltration on the pair "Poultice / limestone from Calatorao" We assume that the curve represents the infiltration on the poultice, given the effect of the rock is considered negligible (it has a very low quantitative value, see coefficients of suction in Table 4b). In figures 4a and 4b we can observe the behavior of the two types of poultices. In the curve of the “GPM” poultice (fig 4a) infiltration begins very fast (0.22 ml/s, stretch in blue) ; as the test tube soaks, the rhythm decreases (0.03 ml / s ; stretch in red), and when apparently, theentire poultice is soaked, infiltration almost stops (0.001 ml/s, stretch in green). This stopping was not complete, although this did not imply that water infiltrated into the stone from Calatorao, as water percolated through the contact surface and the sides. The behavior was very homogeneous within each stretch. The curve of the “handmade” poultice (fig 4b) is similar but presents curves with loose slopes (0.1 ml/s, stretch in blue 0.02 ml/s, stretch in red and 0.003 ml/s, stretch in green) and with a slightly more irregular behavior. e) Desorption: drying speeds The tests were carried out in a controlled atmosphere at 50% RH and 21ºC. In the cases in which the poultices were placed on a waterproof substrate (glass, see table 5), drying occurred slightly faster in “handmade” poultices for the first 8 hours. After 8-10 hours the situation was reversed and “GPM” poultices dried up faster. In the cases in which the poultices were placed on porous substrates (table 6) the opposite happened; at the beginning, the “GPM” poultice dried up much faster but 3 hours later thesituation was the opposite. Regarding the physical evolution and the changes in the volume of the poultices during drying process we can affirm (see table 6 and fig 5): 1) The adhesion was very high in “GPM” poultices and notably lower in “handmade” ones. 2) The loss of volume was greater in “handmade” poultices; these were the only ones that presented superficial cracks. The lateral losses of adhesion were not very significant since they were produced by the contact with a flexible film. © 2023 Global Journals Volume XXIII Issue II Version I 10 ( ) Global Journal of Human Social Science - Year 2023 C Poultices Generated Mechanically with Compressed Air: “Gunpoint Mix System” Characterization and Properties.
