Definitions

• the invention relates to a building or construction element, a construction manufactured making use of such an element and a method of manufacturing such an element.
• the manufacture of building or construction elements is often based on a mechanical strength that renders such an element suitable for serving as a building or foundation element.
• such a building or construction element is provided for, the core of the element, which contains a material with a granular or particulate structure, being wrapped by a foil impermeable by moisture.
• such an element will be less strong than for example a building brick, but, with respect to the prevention of leaching (or the building of a waterproof, for example underground, construction) it is of great value at a low cost price.
• the core material contains waste material. Since waste materials often have a negative value, the cost price can be considerably reduced this way.
• the invention is basically suitable for any waste material, such as, for instance, contaminated sand or rubble
• the objective in accordance with a further elaboration of the invention is in particular that the waste material contains dehydrated sludge, such as paper sludge, sludge from water purification plants and sewage sludge, and/or reduced wood waste and/or manure, either dried or not, etcetera.
• the core with a binding agent, such as glue, plaster or cement.
• a binding agent such as glue, plaster or cement.
• the core may also contain fillers such as sand and grit.
• the core material in particular the waste material present, by, for example, dehydration.
• foam plastic such as substances from which polystyrene foam is produced
• Building or construction elements in accordance with the invention may be applied in many ways, for example as heat and sound insulating covering of walls and noise barriers.
• a higher degree of fire resistance and a better form retainment may be obtained by providing, in accordance with a further elaboration of the invention, that the element is enclosed by a covering of a synthetic material or a curing material such as cement, concrete or plaster.
• a covering of synthetic or curing material such as cement, concrete or plaster.
• it is possible to apply the covering of synthetic or curing material direct around the core and then wrap the foil around it, as well as to apply the covering outside the foil.
• the foil may be made of various materials suitable for the purpose, such as polytene, polypropylene, polyester and/or bitumen, for example a bitumen layer applied to a fibrous web made of a synthetic such as polytene. It will be clear, however, that any material that is suitable for wrapping the core and is impermeable, may be selected as a foil.
• a foil by means of vacuum forming is brought into a spacial shape, such as a bowl or bag, that the core material is put in, and that subsequently the foil is sealed .
• the core material prior to sealing, is brought under sub-atmospheric pressure. It is also possible to compress the core material.
• a building or construction element in accordance with the invention can not only be strengthened externally, for example by using concrete or a layer of plaster, but it is also possible to incorporate such an element into a construction frame and then to cover it with, for instance, metal plate.
• Sealing and protection of an element in accordance with the invention can be further improved by covering the outside with tar, or with bitumen that may be part of a ready available polyester fibre mat or rockwool wall provided with a bitumen layer.
• a favorable embodiment of the invention for processing wood waste is constituted in that wood chips are reduced to particles somewhat coarser than the usual saw dust, and that said particles are mixed with water containing a little glue and to which cement is added.
• base materials for polyurethane foam as well.
• Such an element is light and strong and has good sound absorbing properties.
• Another unexpected advantage is, for example, the possibility of mixing moist manure with sand, the compression of said mixture and its being wrapped by a foil, so that rectangular blocks can be obtained that are excellent to serve as material for improving terrain or raising land surfaces.
• Another application is to the construction of a virtually impermeable partition in dikes.
• the additional sound absorption is a favorable property.
• a sturdy cover layer for example cement
• the combination of sound absorption and thermal insulation may have great advantages, for instance by mounting elements in accordance with the invention against a wall.
• An outstanding application of the invention is constituted in that already dumped waste material can be sorted once again on dumps and the like, and that it can be exploited in a significantly useful way while reducing the total soil and ground water pollution.
