Abrégé

The product is produced from a settable aqueous calcium sulphate dispersion which has a water to solids ratio of less than 0.4 to 1, and has distributed therethrough lightweight hollow bodies having water-impervious surfaces (such as expanded polystyrene beads). The dispersion contains a hydratable cement (such as calcium sulpho aluminate) which is capable of hydration in the presence of the calcium sulphate dispersion. The hydratable cement is such that it reacts with excess water in the dispersion thereby enhancing the water resistance of the resulting product.

A water-resistant calcium sulphate based body comprises a matrix of crystalline calcium sulphate anhydrite, crystals of the matrix being connected to one another by water-resistant phosphate bonding zones, optionally also containing aluminum. The body can be produced by impregnating a porous calcium sulphate with a source of phosphate ions (optionally containing aluminum), and then calcining. Alternatively, a paste comprising calcium sulphate and a source of phosphate ions (optionally containing aluminum) is heated or compressed to form a ‘green body’ and then calcined to produce the body.

A laminated acoustic building panel comprises a pair of plasterboard substrates which are bonded together by an adhesive layer, the panel having a dynamic Young's modulus of 0.1 to 5 GPa and a damping loss factor of 5-30% (η=0.05-0.3), and the ratio of the adhesive to the applied surface area of the substrates being 80-250 g/m2. The laminated panel is relatively soft in construction and hence sound waves caused by knocking or impact noise is surprisingly damped using considerably less adhesive than known panels. The use of soft substrates and less adhesive significantly reduces the weight of the panel. Furthermore, the use of less adhesive significantly reduces costs and makes production easier.

A coating method for gypsum board comprising forming a gypsum board entrained with polymer additive in a surface layer, applying a preferably acrylic primary coating, curling and drying, and passing the gypsum board through a first roll coater wherein a second fluid coating is deposited over the primary layer, which forms a chemical bond with the entrained polymer, and a chemical bond with the second fluid coating. A coating material which can form copolymer bonds with the second coating is then deposited on the same, then dried and cured, resulting in coated gypsum board having a low surface tension surface, essentially impermeable to water, vapor or moisture penetration.

Abrégé

A gypsum stucco composition comprising the following components finely divided; calcium sulphate hemihydrate in calcined solid beta crystalline form; and in intimate mixture with said finely divided calcium sulphate hemihydrate and mixed therewith no later than calcination to form the hemihydrate, a sulphate salt comprising at least one of ammonium sulphate and aluminium sulphate, in an amount such that when the stucco composition is mixed with water and allowed to set, the resulting set plaster has increased compressive strength, flexural strength and/or E-modulus compared to a set plaster produced from said finely divided calcium sulphate hemihydrate containing no said sulphate salt.

Abrégé

Gypsum plasterboard is produced by combining calcium sulphate
hemihydrate (stucco) with water to form an aqueous slurry. Uncalcined gypsum
having a specific surface area below 0.3 m2/g is added to the slurry and the
slurry is
discharged onto a support so as to form a sheet of gypsum plasterboard.
