Definitions

  • the invention relates to a building element, in particular in the form of a formwor block for use in the building industri.
  • Builing elements can also be other forms of building blocks and besides plate-shaped elements.
  • the element can be heat insulated or not insulated, and it is manufactured with sewage and/or industrial waste as an important main constituent.
  • German patent 3,149,173 is directed to a building material based upon industrial waste in the form of an aluminum composition as a main component (sludge) and besides containing among other things a fiber material, such as waste paper.
  • German patent application 3,808,187 describes a building material in granular form manuf ctured of household or industrial waste among other things, and with various additives, for example lime. A relatively cumbersome production method is thoroughly described.
  • German patent application 3,832,771 is closely related to the preceding patent application, and is more particu ⁇ larly related to the production of a material in the form of small spheres.
  • Norwegian patents 154,267 and 157,213 relate to the manufacture of building plates by means of a specific method with waste fibers as a constituent.
  • German patent application 3,440,704 shows a building or formwork block incorporating insulation, groove and tongue connections as well as cavities for the casting of concrete.
  • each such block has a suitable cavity giving room for sanitary and electrical installations (so-called hidden insulation) , at the same time as supporting structures (reinforced concrete) can be provided internally in the blocks.
  • supporting structures reinforcementd concrete
  • the blocks can be provided with grooves and tongues, as well as spaces for reinforcement iron horisontally and vertically.
  • a concrete- filled formwork block based on the solution given here excludes the possibility of thermal bridges, and an additional advantage is represented by the fact that the insulation layer can be located in the interior of the block, but outside the concrete mass and not vice versa, as is the case with other building or foundation blocks.
  • the formwork blocks will have a high safety against fire.
  • Such a formwork block is free of bacteriae, in spite of the type of main constituents being involved in the manufacture. In order to avoid direct contact, however, the blocks should normally be plastered at the inside and outside.
  • This building element is manufactured mainly of sewage and/or industrial sludge to which there is added an equally large or larger proportion of fiber in the form of coarse-cut woodchips and cement.
  • the resulting product will among other things have relatively good elasticity and strength properties.
  • this invention makes it possible to manufacture building elements based on cement, waste sludge and fiber ingredients as main constituents, involving advantages as mentioned above.
  • waste sludge is referred to here, this can be sludge of various types, mainly sewage or household sludge, for example from public purification plants, and various types of industrial sludge.
  • the coarse cut chip constituents in the material in many cases may take the form of a waste product or it can be. specifically produced from waste timber, for example from birch or fir, and the fiber ingredient is washed or impregnated with water glass before being mixed with the remaining constituents for filling into the molds mentioned and subsequent compression as described above.
  • heat may be added, for example heating to temperatures of about 60°C or higher throughout the first couple of hours of the treatment time in the molds. Such heating, however, is not necessary and as a rule not desirable, so as to keep the energy consumption low in the production.
  • the moisture relationships and how quick curing and drying of the blocks are desired, are important factors here.
  • a major condition is that the waste sludge employed has a degree of moisture of 60 to 70 or 75%. A somewhat higher degree of moisture of the waste sludge seems to be possible for the production of plates.
  • the compression When producing plate elements the compression may be in the range from 3.5 to 5 tons per square meter and with a compression time of up to 48 hours.
  • the thickness of the plate element in non-compressed form can be 80 to 90 mm with a compression down to for example 35 mm or other alternative thicknesses which may be desired in the finished plates.
  • the centre composition in the plate elements can be somewhat modified in relation to what is referred to above specifically relating to blocks.
  • cement of quality PC 440 and a somewhat smaller amount of water glass, typically
  • the outside dimensions can suitably have a lenght of 1 meter and width 30 cm and a height of 25 cm as already mentioned above.
  • the height can be directly de ermined by the compression into the molds, or it can be adjusted by sawing at a height of 25 cm after curing and drying, so that crimping of the block is avoided, at the same time as securing that this important outer dimension is exactly maintained.
  • the formwork block in the drawing has a sidewall 1A which is preferably intended to be an inner wall, and another wall IB which correspondingly can be an outside wall in a finished wall structure.
  • An insulation layer 2 is provided at the inside of the outer wall IB.
  • 3A and 3B there are shown a groove and a tongue respec ⁇ tively, for the best possible mutual aligning and joining of adjacent blocks in a wall.
  • a recess 4 in the end wall of the block intended for arranging reinforcement rods and for extending electrical installation wires and the like.
  • the inner cavity 5 can also serve to accomodate sanitary and electrical installations and then to be filled with concrete, so that a sufficient mechanical or load carrying strenght is obtained in the finished wall structure.
  • 6 there are indicated possible subdivision points in the event that it should be desired to cut a comparatively long formwork block into shorter pieces.
  • a building block or formwork block is described here and having a material composition within the ranges quoted, will for example have a breaking strength at compression of 3.5 MPa.
  • the weight should not be too high. To a large degree the weight will be determined by the sludge quality and the amount of cement as well as the final moisture content after the manufacturing process. As regards the contents of cement it will be understood that the low percentages mentioned, are favourable both with respect to weight and economy.

Abstract

Elément de construction comportant comme constituants principaux du ciment, des boues résiduaires et des ingrédients fibreux, visant entre autres choses à une utilisation avantageuse des eaux résiduaires et des boues industrielles. La quantité de boues et la quantité d'ingrédients fibreux qui se présentent sous la forme de copeaux de bois grossiers, constituent ensemble une partie principale substantielle du matériau présent dans l'élément. La proportion de copeaux de bois est approximativement égale ou supérieure à la proportion de boues et la proportion de ciment est de l'ordre de 10%. Pendant la fabrication de l'élément, les boues sont introduites avec un degré d'humidité d'environ 60 à 70%.
