COMPOSITION DE MORTIER FORTEMENT ALLEGE ET ISOLANT THERMIQUE
The present invention relates to a thermally insulating mortar composition devoid of siliceous, calcareous and/or siliceous/calcareous aggregates with a particle size of greater than 100 µm and comprising a mixture of at least: - 40% of inorganic lightening fillers, the bulk density of which is less than 200 kg/m3, - an inorganic binder chosen from sulfoaluminate cements, high-alumina cements and/or binary or ternary binders comprising at least one high-alumina or sulfoaluminate cement, - an air-entraining agent of surfactant type chosen from organic fatty acids, sulfate compounds, sulfonate compounds and/or natural wood resins, and - a viscosifying agent chosen from polyvinyl alcohols, starch ethers, cellulose ethers, guar ethers or clays, such as bentonite. This composition can be used in a spraying device operating in continuous or noncontinuous mode and makes it possible to obtain lightweight hardened mortars by virtue of a very good stability of the paste. The present invention also relates to a process for the preparation of a construction material, to the material thus obtained and to the use thereof in the construction field.
