Definitions

  • the present invention relates to a building composition, a building unit and a method of making same.
  • the text of Australian provisional specification PH6196 and Australian provisional specification PH4396 is incorporated herein by cross-reference.
  • Relatively complicated composition typically comprising many more than three components. Poor fire resistance or fire rating. Poor compression strength.
  • a relatively light block can be built from the composition.
  • the resulting block has good compressive strength and good fire withstand capability.
  • the resulting block will reliably hold screws, nails and the like.
  • a dry mix suitable for making a building unit comprising, by dry weight: sawdust in the range 20% - 50% cement in the range 30% - 50% lime in the range 5% - 20%
  • the mix comprises, by dry weight, about 50% sawdust, about 35% cement, and about 15% lime.
  • a building unit manufactured from the above mix is provided.
  • a method of making a building unit comprising the steps of initially creating a dry mix as defined above, producing a wet mix by mixing said dry mix with water in the above specified proportions, pouring said wet mix immediately into at least one mould, allowing said wet mix to drain and set in said at least one mould, and removing said building unit from said at least one mould upon setting of said wet mix.
  • a building unit and, specifically, a building block is made according to the above method.
  • a mortar mix based on the above described dry mix
  • Figure 2 depicts a mould in an open state suitable for making a block of the preferred embodiment
  • Figure 3 depicts the mould of Figure 2 with tubular inserts inserted
  • Figure 4 depicts a group of moulds as arranged for mass production.
  • An object of at least a preferred embodiment of the present invention is to produce a building composition, building unit and method of making same which possess as a common factor:
  • a building unit in particular a building block having desirable properties and of dimensions 600mm x 200mm x 100mm is constructed as follows:
  • a dry mix comprising by weight 50% sawdust 35% cement 15% lime of sufficient quantity to fill five moulds of internal dimension 600mm x 200mm x 100mm is mixed with 25 litres of water to produce approximately 1 square metre of wall surface area of blocks (5 blocks) of dimension 600mm x 200mm x 100mm.
  • the wet mix is poured into moulds of construction as depicted in Figs. 2 to 4 (except without the tubular inserts) of the internal dimension 600mm x 200mm x 100mm and allowed to set. Excess water mix is allowed to drain naturally frcm the moulds. Setting takes place within 24 hours whereupon the blocks can be released from the moulds.
  • the blocks are allowed to cure for a period of time, for example a few days, at room temperature.
  • the resultant block is preferably of solid construction having no channels or voids within the structure.
  • composition together with the solid structure provides a block having the following characteristics as construed in terms used in the trade: the block will accept screws and nails; the block may be cut without crumbling or cracking; the block weighs under 10 kilograms; the block exhibits excellent acoustic, strength and fire rating properties - fire rating typically 4 hours - compression typically 20 MPa - acoustic insulation minimum 41 dBa.
  • the block of this example is preferably for internal use.
  • 1% glue can be added to the dry weight composition.
  • a building unit, in particular a building block having desirable properties and of dimension 600 mm x 300 mm x 100 mm is constructed as follows: a dry mix comprising sawdust 60%; cement 30%; lime 10% of sufficient quantity to fill five moulds of internal dimension 600 mm x 300 mm x 100 mm is mixed with 25 litres of water to produce approximately 1 square metre wall surface area of blocks (5 blocks) of dimension 600 mm x 300 mm x 100mm.
  • the wet mix is poured into moulds of construction as depicted in Figs. 2 to 4 of internal dimension 600 mm x 300 mm x 100 mm and allowed to set. Excess water mix is allowed to drain naturally from the moulds. Setting takes place within 24 hours whereupon the blocks can be released from the moulds.
  • the blocks are allowed to cure for a period of time, for example, a few days, at room temperature.
  • the resultant block 1 is depicted in Fig. 1 having parallel, circular cross-section voids 2 extending therethrough as shown.
  • the block so produced has the following characteristics as construed in terms used in the trade: the block will accept screws and nails without the need for any form of plug to be initially inserted. The screws and nails are retained in a manner similar to their retention in timber; the block may be cut without crumbling or cracking; the block weighs approximately 9 to 10 kgs which allows it to be lifted unaided by a building worker under current industrial regulations; the block is substantially crack resistant; the block is dimensionally stable under varying conditions of temperature, humidity and age; the block exhibits accoustic, strength and fire rating properties which render it suitable for use in domestic and commercial buildings according to current building regulations and market trends - refer elsewhere in the specification; the block is relatively quick and simple to produce.
  • the material composition of the dry mix can be varied over the following range (by dry weight): sawdust 50-70%; cement 40-20%; lime 10%.
  • the lime composition should always be approximately 10% as indicated above.
  • the sawdust and cement components can be interchanged within the ranges given providing their total comes to approximately 90% of the total dry mix weight. Reducing the cement component makes the resulting block somewhat more brittle and reduces its compressive strength. A variation of a few percent on either side of the above ranges should be allowable in practice and yet still provide a block with the characteristics described. Ambient conditions and the quality of the components may affect these ranges and, therefore, when employing a mix near the endpoints of the specified range trial and error experimentation is advisable to ensure that the required characteristics are indeed produced.

Abstract

Une composition anhydre, utilisée pour fabriquer une unité de construction, comprend, exprimés en poids à sec, 20 à 50% de sciure de bois, 30 à 50% de ciment et 5 à 20% de chaux (oxyde de calcium). Dans un mode de réalisation préféré, ladite composition peut également contenir jusqu'à 1% de colle. L'unité de construction qui en résulte peut servir à former des blocs de construction dont les dimensions sont de préférence égales à 600mm x 300mm x 100mm ou 600mm x 200mm x 100mm. Lorsqu'ils sont fabriqués sous leur forme finale, lesdits blocs présentent des propriétés de compression, de résistance au feu et d'isolation acoustique améliorées.
