Abstract
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 m2/g, preferably greater than 12 m2/g, in particular greater than 14 m2/g and uses thereof.
Claims16
A system based on plant or bio-sourced materials selected from 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 mineral component and a second component;
- wherein said binder composition has a specific surface area calculated according to the BET method, greater than 10 m2/g;
- said second component is selected from the group consisting of slaked lime having a specific surface area, calculated according to the BET method, greater than 22 m2/g,
- and kaolinites, bentonite and wollastonites and mixtures thereof;
- wherein said first mineral component is a binder component selected from the group consisting of cements, slaked lime, standard air lime, natural and artificial hydraulic lime, clays, binders for masonry, binders with pozzolanic and hydraulic setting, gypsum and mixtures thereof;
- and
- wherein at least one from among said first mineral component and said second component is based on powdery slaked lime.
