Abstract

The preservation of historic sites requires the development of sustainable restoration materials.. This work examined the use of aluminum powder as a main component in the manufacturing of environmentally friendly pastes for historical monument repair. These pastes currently present a sustainable remedy by inserting the aluminum powder having special properties such as its light weight and size, resistance to corrosion, and excellent thermal conductivity [1]. By thoroughly examining the mechanical, aesthetic, and sustainability aspects of these materials, this study provides insights into the effectiveness and long-term preservation advantages of aluminum powder-based pastes. Results highlighted that the produced pastes have remarkable mechanical properties, such as high compressive strength, superb adhesion, and dimensional stability. Additionally, they are aesthetically compatible, making it possible to replicate the materials and surface textures of the originals. Aluminum powder-based pastes reduce waste and the carbon footprint of restoration projects from a sustainability standpoint. Case studies that successfully use these pastes in the restoration of historical monuments are included in the publication, showing their efficacy, tenacity, and aesthetic compatibility [1]. All things considered, the incorporation of aluminum powder in environmentally responsible pastes reveals to be a promising development in the preservation and restoration of historical monuments, assuring their preservation for future generations while keeping environmental responsibility.
