A system based on plant or bio-sourced materials selected from among coatings, mortars and concretes of bio-sourced materials comprising a plant or bio-sourced material selected from the group consisting of wood and hemp, and a binder composition comprising a first conventional mineral component and a second component, said system being characterized in that said binder composition has a specific surface area calculated according to the BET method, greater than 10 m/g, preferably greater than 12 m/g, in particular greater than 14 m/g and uses thereof.

System of plant or bio-sourced materials

A binder composition for enhanced mortars and coatings, comprising a first conventional mineral component and a second component based on powdery slaked lime, wherein said second component based on powdery slaked lime has a specific surface area calculated according to the BET method of less than 12 m/g, advantageously less than 11 m/g, in particular less than 10 m/g, preferably less than 9 m/g and its uses as well as the enhanced coating or mortar systems comprising an aggregate of the mineral type and the aforesaid composition.
