Definitions

  • the invention is directed to a construction product for producing a wall and/or for cladding a building shell, for example in the form of a brick or a facade element, in particular a wall brick, wherein the construction product has a matrix made of a solid building material and with at least one perforation, with a volume proportion of all perforations, based on the volume delimited by the external dimensions of the brick, of 30 vol.% or more.
  • Solid building materials are currently classified as a source of CO 2 rather than a sink. Initial developments in the concrete industry are aimed at developing solid building materials as CO 2 sinks. By using bio-coal in the concrete recipe, the carbon contained in the bio-coal is removed from the natural CO 2 cycle for very long periods of time, cf. e.g. the "climate concrete” from Klark, Switzerland.
  • the invention provides that at least one filler material in the cavities of the construction product is filled with a bulk substance made of an organic material from a renewable raw material with the ability to store carbon, i.e. a bulk substance which is able to permanently store carbon in the construction product and/or store it therein, wherein the organic filler material integrated into the at least one perforation of the matrix made of a solid construction material has a bulk density or filling density of 100 kg/m 3 or more.
  • the substance with the ability to store carbon is added to the building product, which can be processed without further firing, so that it is not exposed to increased temperatures.
  • the building product can comprise a solid building material with a perforation, with a volume proportion of the perforation, based on the volume delimited by the external dimensions of the brick, of 25 vol.% or more, in particular of 30 vol.% or more, wherein at least one filling material made of an organic material for carbon storage is integrated in the cavity of the perforation, i.e. a Material that is capable of permanently storing and/or storing carbon.
  • this perforation is a macroscopic perforation, such as that found in perforated or hollow bricks, especially in vertically perforated bricks and long-hole bricks, etc.
  • Elements for a thermally insulated facade, such as those offered by Schlagmann Poroton GmbH & Co. KG, are also very suitable.
  • the organic filling material integrated into at least one perforation has a bulk density or filling density of 80 kg/m 3 or more, in particular of 100 kg/m 3 or more. This ensures that a large amount of carbon can be incorporated and stored.
  • the bulk substance has a carbon content of 40 kg carbon per cubic meter or more, preferably a carbon content of 50 kg carbon per cubic meter or more.
  • the proportion of pure carbon in dry wood is about 50% by weight.
  • the filling material to be filled into a hole in the solid building material is crushed into a flour, powder or granulate and/or into straws, fibers or pellets.
  • a further advantage is that a powdered material is generally not as dense as a solid wood body, so that a finished building block is still comparatively light despite the filling material it contains and can therefore be easily transported or handled on a construction site.
  • air which fills the voids in such a flour, powder or granulate between the particles, fibers, stalks and/or pellets, is also a very good thermal insulator, so that the finished product thereby obtains optimal thermal insulation properties.
  • the preferred particle size of the organic filling material is between 0.01 mm and 5 cm, for example between 0.1 mm and 2 cm, in particular between 0.5 mm and 1 cm, particularly preferably between 1 mm and 5 mm.
  • Biogenic CO 2 storage can be integrated into the hole geometry of the building product, which has taken CO 2 from the air through photosynthesis and stores it as carbon in the structure. Cereal residues, hay, straw, wood, tree bark, bark mulch, spelt husks, sawdust, nut shells, fruit stones, olive stones, pine bark, miscanthus, hemp, biochar, charcoal, biochar or organic mixtures.
  • the proportion of carbon in the total filling mass is preferably in the order of 50 wt.%, for example between 35 wt.% and 65 wt.%.
  • the atomic mass unit u or Da is defined as one twelfth of the atomic mass of an isolated atom of the carbon isotope 12 C in the ground state.
  • an oxygen atom has an atomic mass of approximately 16 u or 16 Da.
  • a carbon atom with an atomic mass of approx. 12 u or 12 Da can be extracted from a carbon dioxide molecule with an atomic mass of approx. 44 u or 44 Da.
  • the invention provides that the C content in the bulk substance removes 125 kg of CO2 or more from the air per cubic meter of the bulk substance, for example 150 kg of CO2 or more, preferably 175 kg of CO2 or more.
  • the carbon content in the bulk substance can remove up to 2,500 kg of CO2 from the air per cubic meter of bulk substance, for example 2,250 kg of CO2 or less, preferably 2,000 kg of CO2 or less. Measurements have shown that the carbon content in charcoal, but also in pellets made of hemp, straw or similar, can remove up to 1,000 kg of CO2 from the air per cubic meter of bulk substance; Charcoal pellets were able to remove up to 2,500 kg of CO2 per cubic meter of bulk substance from the air.
  • the invention further recommends providing the organic materials integrated into the hole channels with substances that are suitable for binding or impregnating and/or ideally can also bind CO 2 from the air.
  • substances that are suitable for binding or impregnating and/or ideally can also bind CO 2 from the air In particular, metal oxides or hydroxides are considered here.
