Title (EN) DRY CONSTRUCTION COMPOSITION WHICH CAN BE WET-SPRAYED BY MEANS OF A SCREW PUMP AND COMPRISING A BINDER AND A BIO-BASED FILLER - PREPARATION AND USES OF SUCH A COMPOSITION
(FR) COMPOSITION DE CONSTRUCTION SECHE PROJETABLE EN VOIE HUMIDE A L'AIDE D'UNE POMPE A VIS ET COMPRENANT UN LIANT ET UNE CHARGE BIOSOURCEE - PREPARATION ET APPLICATIONS D'UNE TELLE COMPOSITION
Abstract: front page image
(EN)The invention relates to a dry construction composition, which can be easily wet-sprayed by means of a screw pump, forming an insulating, mechanically strong material (λ<0.1 W·m-1·K-1) after hardening, in a sustainable manner. This composition comprises: -A- at least one binder which in turn includes: -A1- at least one primary binder comprising lime and/or at least one source of alumina and/or at least one source of calcium sulphate, preferably at least one source of alumina; -A2- at least one water-retaining agent; -A3- preferably at least one surfactant; and -B- at least one bio-based plant filler consisting of sunflower stalks and/or corn stalks and/or rapeseed stalks having an apparent density, in kg/m3, of less than 110, preferably of 10 to 80, the B/A ratio (litres/kg) being comprised between 2 and 9; this composition being intended for being mixed with water in a water/binder -A- ratio no lower than 0.8. The invention likewise relates to the wet composition, to the preparation thereof, to the binder -A- taken in isolation, as well as to a method for application by spraying, onto a horizontal or vertical substrate, or by moulding.
(FR)L'invention concerne une composition de construction sèche, facilement projetable en voie humide à l'aide d'une pompe à vis, formant après durcissement, un matériau isolant (λ<0,1 W·m-1·K-1) et mécaniquement résistant,de manière durable. Cette composition comprend: -A-au moins un liant incluant lui-même: -A1-au moins un liant primaire comprenant de la chaux et/ou au moins une source d'alumine et/ou au moins une source de sulfate de calcium, de préférence au moins une source d'alumine; -A2-au moins un agent rétenteur d'eau; -A3-de préférence au moins un surfactant; -B- au moins une charge biosourcée végétale à base de tige de tournesol et/ou de tige de maïs et/ou de tige de colza présentant une Masse Volumique Apparente (MVA) en kg/m3, inférieure à 110; de préférence comprise entre 10 et 80; le ratio B/A (litres /kg) étant compris entre2 et 9; cette composition étant destinée à être gâchée avec de l'eau selon un rapport eau /liant -A- supérieur ou égal à 0,8. L'invention a également pour objet la composition humide, sa préparation, le liant -A-pris 2 isolément, ainsi qu'un procédé d'application par projection,sur un support horizontal ou vertical, ou par moulage.
