Expected results

  • Define the main forms of functional alteration and degradation in relation to specific stone substrates.
  • Determine the environmental conditions of the deterioration of the artefacts, with the identification of the responsible agents, in relation to the characteristics of the sample site. The currents, the depth, the type of substrate considerably affect the processes and forms of degradation in the submerged marine environment . It will be essential to develop a specific multivariate model that takes into account all the knowledge related to degradation processes by correlating the interactions among the biological, climatic, orographic, planimetric variables with the marine currents and the in/out movement of the sediments.
  • Relate the action of protective products with the criticality threshold to be applied to the agents responsible for a specific degradation.
  • Test the actual effect and the limit conditions of the new formulations combined with low-impact nanoparticles already on the market, according to the elevation of the criticality thresholds.
  • Formulate new products with multifunctional properties. These will be obtained by mixing in the correct proportions biocidal products and consolidants. These latter, other than conferring rebonding properties to the product, will support the biocides themselves. The use of emulsifiers, stabilizers, wetting improvers and other additives will be considered in order to improve the properties of the products. The formulations will be selected according to their stability and some thermal aging analyses will be conducted on them.
