pressure), the absorption speed and the total volume of infiltrated water were measured until, besides the poultice, the rock also began to absorb water. This moment could be established very precisely; the slope of the infiltration curve varied substantially (fig.4). In each test we measured the absorption coefficient (in two modalities); first, as Cumulative Linearization (CL), that corresponded to the calculation method of the coefficient of absorption by linear regression of the first infiltration values with respect to the square root of time. The second one corresponded to the numerical optimization method of the simplified equation of [25] Haverkamp (1994). The latter, being more precise, coincided with the suction coefficient and therefore was directly comparable with the coefficient calculated for substrates according to the RILEM method. (22) Table 4 shows the values of the six tests carried out, in which it can be seen that “GPM” poultices have coefficients and absorption speeds of more than double that of the “handmade” ones. The detail of the infiltration curves on the poultice / substrate pair was reproduced in one of the cases (stone from Calatorao), so that the calculation steps can be understood. In the case mentioned, the rock presented a very low suction coefficient (table 4b) and was adequate to delimit the behavior of the poultice. Fig. 4: Infiltration curves of the two types of paper on Calatorao St. The reduced graph with a line is the one used to calculate the coefficient using the most characteristic section. The large graph in each case represents the behavior throughout the test time. The infiltration begins very fast, stretch in blue; Within this section you can see a faster first behavior (the water is only entering the papeta) and a slightly slower second (the water enters the papeta and also into the rock.) The green stretch corresponds to the absorption of the rock in its early stages (surface of the active but unsaturated rock.) The final red stretch corresponds to the slowest absorption ofthe rock when it has the entire saturated suction surface. © 2023 Global Journals Volume XXIII Issue II Version I 9 ( ) Global Journal of Human Social Science - Year 2023 C Poultices Generated Mechanically with Compressed Air: “Gunpoint Mix System” Characterization and Properties.
