    摘要： A partition for a building structure comprises a support frame and a plasterboard affixed to the support frame with a plurality of screws. The plasterboard comprises a gypsum matrix having fibres embedded therein in an amount of at least 1 wt % relative to the gypsum, as well as a polymeric additive that is present in an amount of at least 1 wt % relative to the gypsum. The support frame comprises a plurality of elongate timber members and the average spacing between nearest-neighbour screws is greater than 400 mm.

    摘要： An apparatus for preparing foam for incorporation into cementitious slurry comprises a conduit having an inlet for receiving a gas feed and a surfactant feed, and an outlet for allowing the exit of foam. The conduit houses a porous plug that provides a partial barrier to fluid flow along the conduit, the plug comprising a plurality of particles that are packed in a regular array and that define a three-dimensional network of pores extending therebetween. The apparatus comprises a resilient component located between the plug and the conduit.

    摘要： Lightweight construction panels, such as plasterboard, (e.g. gypsum plasterboard) are commonly used to provide internal partitions in buildings. Due to the use of plasterboard as in internal partition, it is desirable for plasterboard to absorb and block sound energy, such that sound from one room is not easily heard in an adjacent room. It has been found that providing micro cracks in the gypsum matrix of a gypsum-based panel improves the acoustic characteristics of the panel. Apparatus 300 is provided for cracking a gypsum matrix of a gypsum-based panel 10, the apparatus 300 comprising: a roller assembly 320, the roller assembly 320 configured to receive the panel 10 at an entrance of the roller assembly 320 and convey the panel 10 from the entrance to an exit of the roller assembly 320, wherein, between the entrance and the exit, the roller assembly 320 is configured to bend the panel 10 in a first direction.
