Abstract (en)

[origin: WO2017077246A1] The invention relates to a dry construction composition that is easily wet-sprayable by means of a screw pump, thus forming, after hardening, a durably mechanically resistant insulating material ( ë <0.1 W·m-1·K-1). Said 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. Said composition is intended to be mixed with water in a water/binder ratio -A- of no lower than 0.8. The invention also relates to the wet composition, to the preparation thereof, to the binder -A- taken in isolation, and to a method for application by spraying onto a horizontal or vertical substrate or by molding.
