A method includes using copolymers including at least polyoxyalkylenated monomer units and at least phosphorus-comprising monomer units as water-reducing agent in hydraulic binders.

Water-reducing agent for hydraulic binders

A method includes adding at least one copolymer or a salt thereof acting as a plasticizer, blocking agent, or both a plasticizer and a blocking agent, to a calcium sulphate-based hydraulic binder. The copolymer includes an acrylic acid or a poly(oxy)alkylene copolymer.

Admixture for hydraulic binder

A method of using an admixture in hydraulic binders, in particular in plaster-based or anhydrous calcium sulphate-based compounds, the admixture being an acrylic polymer with controlled end chains.

Admixture for a hydraulic binder

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 Dis greater than or equal to 100 &#x3bc;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.

Finishing compound suitable for an acoustic support

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 &#x3bc;m and excluding fine fillers; 0.1 to 8% of synthetic or animal fibers; 0.5 to 35% of binder.
