Abstract: The invention relates firstly to a waterproof laminated sound insulation system, in particular for flooring. This system provides sound insulation, in particular against impact noise, in compliance with current regulations, and also satisfactory pressure resistance and satisfactory deformability. The invention also relates to a kit comprising the waterproof laminated system, to the use of fillers having a density of less than 1.2 g/cm3 in an adhesive composition for increasing the sound insulation of floors, and to the method of laying a waterproof laminated sound insulation system.

Abstract: The present invention relates to a hydraulic binder composition comprising: at least one Portland cement; at least one amorphous calcium aluminate; calcium sulfate; at least one alkaline salt S chosen from K2CO3, Rb2CO3, Cs2CO3 and mixtures thereof; the composition being characterized in that the mass ratio of alkaline salt(s) S to amorphous calcium aluminate(s) ranges from 0.01 to 0.2.

Abstract: The present invention concerns a composition comprising: —0.68% to 1.00% by weight of a silsesquioxane (A) comprising at least one phenyl group and at least one alkoxy group; —at least one silylated polymer comprising at least one alkoxysilane group, preferably 3% to 80% of at least one silylated polymer comprising at least one alkoxysilane group; and at least 25% by weight of at least one carbonated filler, percentages by weight being expressed with respect to the total weight of said composition, as well as the use of same as a mastic, in particular as a mastic for construction.

Abstract: The invention relates to a liquid bi-component composition comprising a silylated polymer having alkoxysilane functions, an epoxy resin, an amine catalyst for the epoxy and a catalyst for silanol condensation, and an adhesion promoter or a coupling agent. After crosslinking, the liquid composition according to the invention makes it possible to obtain a waterproofing membrane suitable for pedestrian and/or vehicle traffic.
