The MaTaCoS project aims to provide innovative methodologies and materials in the field of conservation and restoration of artifacts in submerged archaeological areas.

Several tools will be developed for cleaning stone surfaces and for diagnostic operations. The main R&D issues related to the development of electromechanical cleaning and diagnostic devices mainly concern:

• Preserving the find during cleaning operations; don’t pollute the site with the residues of the cleaning; the sizing of the devices based on required autonomy and operational depth;

• The choice of the best materials for the realization of the devices;

• The definition of the most appropriate FEM, CFD and Multibody simulation parameters for the virtual simulation of device performance;

• The reproducibility of laboratory test conditions in the real environment.

In order to solve these problems, it’s foreseen the preparation of appropriate test benches to test the devices in the laboratory and the use of last generation testing machines for the execution of materials tests.

The mortars used for underwater restoration don’t show good performance as they are not characterized by great strength and good applicability and are not equipped with particular bio-inhibitory characteristics. Therefore, the goal is to formulate high-performance mortars for specific use in the underwater environment. The formulation foresees the use of hydraulic binders, specific aggregates, additives that avoid dispersion in the application phase and biocidal agents, even nanostructured.

In addition, a remote monitoring system will be set up to monitor the degradation of sites over time, allowing for proper maintenance operations planning.

The project will open up interesting business opportunities for companies in the partnership, as it will allow them to diversify their production by intervening in an emerging market that is currently potentially growing.
