Process for the formulation of natural mortars based on the use of a new natural hydraulic binder

In the so-called “circular economy”, i.e., an economy capable of selfhealing, waste is not disposed of as in the natural operational evolution of the work but reused. This leads to a reduction in the impact of the building that uses it and an increase, even if ideological, of its value. Respecting the principles of the circular economy, the present study has an aim for the formulation of natural mortars with hydraulic behavior that foresees the reuse of the material coming from the restoration site. At the base of these mortars, there is a new hydraulic binder obtained from the “complete” combination between lime and cocciopesto, a reaction that does not allow the development of residual free lime. Thanks to this feature, and to the lack of its consequences, the obtained mortars can be used to recover the historical buildings also having an archaeological and artistic interest.
