The main goal of the project was to develop high-performance composite materials with functional properties suitable for technical applications in the construction and marine sectors. The material developed as part of the project consisted of the following components: a geopolymer matrix (GP) reinforced with fibres and/or particles. This composition was designed to meet performance requirements that could not be achieved with a single component alone. The matrix, fibres, particles and fillers were sourced from both mineral and synthetic sources.

The project led to the development of environmentally friendly, high-performance composites for underwater applications. These materials met the need for more durable solutions to protect hazardous wrecks and critical underwater infrastructure from corrosion, as well as to support construction activities in harsh or heavily polluted environments. The developed elements were manufactured as prefabricated or 3D-printed components that can be installed underwater. Their geometries were specifically tailored to specific wrecks or underwater locations. Compared to conventional construction and repair materials, the materials demonstrated improved corrosion resistance, increased durability, better workability, cost efficiency and architectural adaptability.

MAR-WRECK had a strong scientific character and focused on developing innovative products and advanced technologies demanded by the market. The project responded to societal and industrial needs. The materials developed offered environmental benefits due to their low carbon footprint and the use of raw materials from waste. The final composite products could be used for environmental protection, including protecting hazardous wrecks and other critical underwater structures from corrosive environments.
