COMPOSICION DE CONSTRUCCION SECA PROYECTABLE EN VIA HUMEDA CON LA AYUDA DE UNA BOMBA A TORNILLO Y QUE COMPRENDE UN LIGANTE Y UNA CARGA DE ORIGEN BIOLOGICO - PREPARACION Y APLICACION DE DICHA COMPOSICION
A dry construction composition is easily wet-sprayable by means of a screw pump, thus forming, after hardening, a durably mechanically resistant insulating material (λ<0.1 W·m−1·K−1). The composition contains: —A— at least one binder, itself including: —A1— at least one main binder containing lime and/or at least one alumina source and/or at least one calcium sulfate source, preferably at least one alumina source, —A2— at least one water-retaining agent, and —A3— preferably at least one surfactant; and —B— at least one biosourced filler, preferably of plant origin. The ratio B/A (liters/kg) is between 2 and 9. The composition is intended to be mixed with water in a water/binder ratio —A— of no lower than 0.8. Also disclosed is a wet composition, the preparation thereof, to the binder —A— taken in isolation, and to a method of spraying the composition onto a horizontal or vertical substrate or by molding.
