Transdisciplinary approach for the modern formulation of construction materials, a paradigm shift in the protection of immovable cultural heritage

PN-IV-P7-7.1-PED-2024-0286 (77PED/2025)

Ancient monuments and structures endorse our historical past, bearing testimony to past events, concerns for the preservation and enhancement of the cultural heritage in the past decade being a challenge for the specialists.

Project goal

The main scientific objective of the project ConstructHer is to propose a promising, cost-effective and environmentally friendly alternative to the currently used solutions, with multi-valent use (both for cultural heritage protection and for civil constructions with special requirements, such as hospitals, etc.,) based on development of technologies for obtaining constructions materials (plastering mortars, cement, plaster) with biocidal and photocatalytic properties, due to its enrichment with natural compounds and metallic nanoparticles obtained via “green chemistry routes” from natural resources (plant extracts).

General objective

The challenge of the ConstructHer project is to obtain tuned morphologies of the metallic nanoparticles and to find optimal ratio of the component of the construction material (ratio solid: liquid), in order to obtain a maximum antibacterial effect (an important factor is the tendency of nanoparticles to aggregate and agglomerate, which significantly influences their effectiveness; the optimal use and dispersion of nanoparticles, in quantities that ensure the antibacterial properties of the building material, while maintaining the mechanical parameters at least at the same level).

Phase I

Development and establishment under laboratory conditions of an integrated research strategy to obtain innovative materials for conservation/restoration.

Implementation period: 05/05/2025 – 31/12/2025

Activities:

  • Development of optimal protocols (under laboratory conditions) of extraction methods with maximum extraction yield for phytoconstituents from plants and AgNP phytosynthesis;
  • Development of simulated models (plaster mortar, cement, gypsum, etc., compatible with the constituent elements of immovable cultural heritage) to test the antibacterial and photocatalytic effect of the obtained extracts and nanoparticles;
  • Development of analytical methods and protocols for the characterization and chemical analysis, analysis of the antibacterial and photocatalytic effect of the obtained extracts and nanoparticles;
  • Development of optimal protocols of methods for the formulation and characterization of building materials (plaster mortar, cement, gypsum) by adding plant extracts and AgNP;
  • Obtaining and characterizing innovative materials; demonstrating the functionality of the proposed technical solution – Part I;
  • Obtaining and characterizing building materials – Part I;
