Evaluation of effectiveness of silicoorganic treatments using hydric properties

In this work, the effectiveness of silicoorganic treatments for the consolidation, with or without waterproofing, of silicified stones (one conglomerate and four sandstones) from Zamora is analyzed, provided that these treatments are applied in the same way. Changes in the following properties have been monitored: total and free porosity, real and apparent density, absorption coefficient, imbibition coefficient, and capillary absorption coefficient. These intrinsic stone properties and the treatments employed have a significant effect on changes in these variables and lead to differences in the transport of fluid in the stone. This is the first time that the Canonical Biplot has been applied to this type of data to determine the control of the effectiveness of silicoorganic treatments applied to rocks. It was observed that the double action treatment RC80, which includes both waterproofing and consolidating, is more effective than the consolidating treatment RC70.
