Evolution of a patent work applied: formulation of sustainable mortars with a new natural hydraulic binder on site

The present research study concerns the formulation of natural mortars with hydraulic behaviour, used for the restoration of the walls of historical buildings. The research aim – based on a patented procedure – is to provide an answer to the conservation of these buildings, often having archaeological and artistic interest. In accordance with Life Cycle Assessment principles, the production process of the mortar can also be carried out at the restoration site, involving a low environmental impact. Thanks to its characteristics, the natural mortar object of this research study can represent a valid alternative to Portland cement.
