    Abstract: The present invention provides a calcium sulphate-based product (e.g. a wall board) comprising gypsum, a pozzolan source such as a clay additive, rice husk ash or diatomaceous earth and a metal salt additive. The product may be produced by drying an aqueous slurry comprising calcined gypsum, the pozzolan source and the metal salt additive. The clay additive may be a kaolinitic clay. The metal salt additive may be a magnesium salt e.g. magnesium nitrate, magnesium chloride or magnesium hydroxide.

    Abstract: The present invention provides calcium sulphate-based product having reduced shrinkage after exposure to high temperatures, the product comprising gypsum, a pozzolan source (e.g. in an amount between 4-27 wt %) and a metal salt additive (in an amount between 0.5 and 10 wt %). The pozzolan source may be selected from a kaolinitic clay material, fly ash, rice husk ash, diatomaceous earths, volcanic ashes and pumices, micro-silica, silica fume and silicone oil. The metal salt additive may be a metal salt which decomposes between a temperature of 300-500° C. to yield a metal oxide, e.g. magnesium nitrate.

    Abstract: A partition, mounted on a mounting surface, comprises a plurality of elongate upright members, a first board and a second board. The first board is mounted on one side of a pair of the elongate upright members that are adjacent to each other, and the second board is mounted on the other side of the same pair of adjacent elongate upright members, so as to provide a cavity between the pair of elongate upright members and the first and second boards. The partition further comprises a spacer that is located within the cavity, the maximum dimension of the spacer in the through-thickness direction of the partition being at least 90% of the separation of the two boards. The spacer may help to reduce the extent of inward bowing of the boards between adjacent elongate upright members, so that, for example, the upright members may be spaced further apart.

    Abstract: Lightweight construction panels, such as gypsum plaster-board, are commonly used to provide internal partitions in buildings It is known to cover, either partially or fully, the panel with an aqueous material such as gypsum plaster or jointing compound. It has been found that known panels expand when they absorb water. This gives rise to several undesirable results such as the gypsum plaster or jointing compound cracking as the panel expands as moisture is absorbed. The present invention provides a panel comprising a gypsum matrix including fibres in an amount of at least 0.8 wt % relative to the gypsum, a polymeric additive in an amount of at least 0.8 wt % relative to the gypsum, and at least one phosphate additive. A panel having such a composition has been found to have desirable characteristics.
