Analysis on adhesives for stone conservation: a preliminary evaluation of potential sustainable alternatives
Main Article Content
Abstract
This research aims to explore the possibilities of using plant-based biopolymers as sustainable adhesives for both natural and artificial stone, in such a way that the product would be compatible with the substrate from both a chemical and a mechanical point of view, and would fulfill the criteria of sustainability and reversibility. Mixtures based on soy-protein and lime were tested by comparing their mechanical performance and properties to that of commonly used synthetic adhesives. The preliminary results show that they are potentially effective. Further research should be developed, so as to improve their properties and better understand their long-term behavior
