Abstract: A method for producing a composite insulating mineral construction element includes filling the cavity of a construction element including at least one cavity delimited by at least one inner wall at least partially having a water absorption rate of more than 5 g/(m2·s) at 10 minutes according to standard NF EN 772-11 of August 2011 with a foamed cement slurry including a cement being an hydraulic binder including a proportion of at least 50% by weight of calcium oxide CaO and silicone dioxide SiO2, a metal salt selected from an aluminium, magnesium or iron salt and mixtures thereof, and a cellulose ether; and leaving the foamed cement slurry to set within the cavity resulting in the formation of a mineral foam, wherein the foamed cement slurry includes from 0.01 to 0.2% by weight of cellulose ether, relative to the weight of cement.

Abstract: A finishing compound having acoustic properties and including in percentage by weight relative to the total weight of the product, at least 25 to 80% of water; 0.1 to 5% of a thickening agent; 0.01 to 0.8% of a dispersing agent; 10 to 60% of a monogranular filler wherein the D50 is greater than or equal to 100 ?m; 0.5 to 6% of binder; and not including a foaming agent; and presenting permeability to air after evaporation of the water from 800 to 6000 mks Rayls.

Abstract: A finishing compound having acoustic properties and including in percentage by weight relative to the total weight of the product, at least 10 to 70% of water; 0.1 to 5% of a foaming agent; 0.1 to 5% of a thickening agent; 35 to 70% of a monogranular filler having a size greater than or equal to 100 ?m and excluding fine fillers; 0.1 to 8% of synthetic or animal fibers; 0.5 to 35% of binder.
