Definitions

  • the present invention relates to a water-resistant building material, such as, a panel or sheet.
  • the building materials currently used in internal wet areas are composed of compressed cellulose cement or water-resistant plasterboard.
  • a water-resistant building material which has improved long term water-resistance and maintains an acceptable strength after considerable exposure to moisture. According to the present invention there is provided a water-resistant building material which comprises:
  • a method for producing a water-resistant building material which comprises: mixing 0.2 to 6% by weight of water-proofing additive, 0.5 to 10% by weight of fly ash, 0 to 5% by weight of Portland cement and the balance being plaster of Paris and optionally at least one other additive with water to form a slurry; pouring the slurry into a mould; allowing the slurry to hydrate and set; and drying the building material at 50 to 150 °C.
  • a water-resistant plasterboard construction which comprises: at least one layer of fabric; and a layer of the water-resistant building material described above.
  • the water-resistant building material is preferably a sheet or panel for internal or external use.
  • the water-proofing additive may be of any suitable known type, for example, melamine formaldehyde, polyvinyl alcohol, paraffin wax emulsion, silicone emulsion, silicone oil, polyvinyl acetate and bitumen emulsion.
  • concentration of water-proofing additive in the building material is 0.4 to 4% by weight of the total composition.
  • the concentration of fly ash in the building material is preferably 1 to 6% by weight of the total composition.
  • the concentration of Portland cement in the building material is 0 to 3% by weight of the total composition.
  • the concentration of gypsum in the building material is preferably 80 to 96% by weight of the total composition.
  • the other additive which may be present includes fibrous reinforcement, for example, cellulose fibre or chopped fibreglass and light weight filler, for example, waterproof perlite. It will be appreciated that the present invention is not limited to these additives and may include other additives used in the art.
  • the improved water-resistance is preferably obtained by incorporating low concentrations of fly ash and optionally Portland cement with the plaster of Paris, together with the water-proofing additive.
  • the water-proofing additive acts in conjunction with the low concentrations of ettringite formed and this significantly improves the long term water-resistance compared with that achieved by using the water-proofing additive or the fly ash and Portland cement.
  • the water-resistant building material comprises:
  • the water-resistant plasterboard construction preferably comprises one layer of fabric and one layer of paper with the water-resistant building material being sandwiched therebetween.
  • the fabric preferably forms the layer which is exposed to the water.
  • the fabric may be composed of either naturally occurring fibres or man-made fibres.
  • the fabric is composed of man-made fibres based on natural organic polymers such as rayon or of man-made fibres based on synthetic organic polymers such as olefin.
  • Particularly preferred fabrics are viscose rayon, more preferably Lantor (Registered Trade Mark) filter or spunbonded polypropylene, more preferably Evolution (Registered Trade Mark) fabric.
  • the water-resistant plasterboard construction may be produced by any suitable known process, preferably a continuous process.
  • a particularly preferred continuous process will now be described by way of example only with reference to the accompanying drawing in which:
  • Figure 1 is a side view of a continuous process for the production of a water-resistant plasterboard construction in accordance with the invention.
  • the components of the water- resistant building material 2 are metered into a mixer 4 which discharges a slurry 6 onto a layer of paper 8 which is transferred onto a conveyer belt 10.
  • the fabric layer 12 then sandwiches the slurry and after the edges are sealed, the water-resistant building material 2 is allowed to set.
  • the slurry impregnates the fabric and on setting the gypsum crystals formed provide a strong bond with the fabric.
  • the fabric reinforces the surface and contributes significantly to the flexural strength of the plasterboard construction.
  • the plasterboard is cut into desired lengths and dried.
  • the above components were mixed with water in a ratio of 50-90mls of water to lOOgms of powder and other liquid additives used in the art to form a slurry.
  • the slurry was mixed using a suitable mixer such as a propeller type mixer, and was poured into a mould and allowed to hydrate and set. After setting the mould was removed and the cast building slab was dried in a heated air circulating drying kiln.
