Definitions

  • the invention relates to a concrete mixture comprising binders, water, concrete aggregates and concrete additives.
  • walkways are usually illuminated for safety, road or lane markings, - guides or limits by markings and / or lights highlighted, illuminated emergency exits, obstacles highlighted by lighting or reflective painting, etc.
  • the object of the present invention is therefore to provide a simple and permanent possibility for luminous markings or parts.
  • the concrete mixture further comprises photoluminescent luminescent pigments
  • the concrete mixture further comprises photoluminescent luminescent pigments
  • the lighting of the objects is resistant to wear and weather, as the lamp is evenly distributed throughout the material and appears as long as the concrete layer in which it is contained, was completely removed or weathered.
  • the luminescent pigments are therefore not only present on the surface, but integrated into the concrete composite. As a result, a high mechanical abrasion resistance is achieved because the pigments are protected by the adjacent sand and quartz particles. Maintenance or replacement of bulbs is not necessary.
  • the concrete mixture can be used as a base mixture for the production of virtually any known concrete, in particular a concrete selected from the group consisting of site concrete, ready-mixed concrete, shotcrete, underwater concrete, rolled concrete, spun concrete, vacuum concrete, construction concrete, screed concrete, aerated concrete, fiber concrete, mineral concrete, concrete concrete, self-compacting concrete, high-strength concrete, ultra-high-strength concrete,
  • Glass foam concrete, self-cleaning concrete, acid-resistant concrete complementary to translucent concrete, exposed concrete, asphalt concrete, chippings, polymer concrete, in-situ concrete, paper concrete.
  • the luminescent pigments may be fluorescent and / or phosphorescent or luminescent luminescent pigments. Depending on the intended use, combinations of pigments of these different pigment classes are also possible. Thus, fluorescent and phosphorescent pigments can be mixed, so that special effects and optical designs are possible. The combination of different luminescent pigments for Achieving "mixed" effects through different colors, brightness, duration of light, etc. is an option.
  • the luminescent effect usually occurs only with illumination of the objects UV-containing light, depending on the pigment and only at certain frequencies in appearance.
  • Fluorescent pigments can have different colors in daylight.
  • the daylight color and the occurring luminous color on irradiation with light of the activation frequency may be different or the same.
  • pigments When selecting pigments, it is important to ensure that the pigments can withstand the environment (moisture, strong UV radiation, etc.), especially in outdoor use.
  • phosphorescent and fluorescent pigments can also be used in the production of the concrete mixture. This results in a glow under UV irradiation and a glow in the dark. A pleasant added benefit is that the light needed by the fluorescent effect charges the phosphorescent pigments at the same time.
  • An example of an application of paving bricks made from mixed luminous mixtures is the use as paving stones to mark parking areas.
  • the concrete mix was produced with pigment of the daylight color white and the UV light color blue.
  • the pigment is UV stable and therefore suitable for outdoor use.
  • the white daylight color ensures that the paving stones look like normal white paving stones during the day and are indistinguishable from conventional parking paving stones.
  • the parking lot lighting is switched on.
  • the standard lamps and black light bulbs are used or supplemented in the existing lamps. As soon as the black light lamps are switched on, the fluorescent paving stones glow in the blue luminous color. If this light is switched off, the lighting effect goes out.
  • luminescent pigments are used which luminesce in the visible range.
  • Particularly preferred are the use of sulfides and / or aluminates and / or phosphorus-based pigments as luminescent pigments.
  • the luminescent pigments comprise strontium aluminates, fluoroaluminates or zinc sulfides.
  • the luminescent pigments for the alkaline environment of the concrete are stabilized.
  • Alkaline protection is important because the cement in the concrete is very alkaline when applied and cured, at max. pH about 12.6.
  • Acid protection may also be important, depending on the later use of the product being made.
  • Cement products are generally susceptible to acids as acids dissolve the cement structure. Depending on the application of the cement end products they can therefore be protected against acids. Accordingly, care must be taken to ensure that the pigment is not destroyed.
  • phosphonic acid is used in the concrete sector for this purpose.
  • Phosphonic acid is also a standard retarder in the concrete field, and in this case too, the pigment must be tailored to it. Protection of the pigment must also be given in this case.
  • the concrete mixture preferably contains from 1 to 50% by weight, preferably from 10 to 40% by weight and in particular from 20 to 30% by weight, of luminescent pigments. The proportion of luminescent pigments depends on the desired luminosity and the luminous power of the pigments.
  • any concrete binder can be used.
  • cement preferably white Portland cement
  • a polymer concrete binder may be included in an amount of up to 70% by weight. If both cement and polymer binder are contained in the concrete mix, the cement actually only has filler function and correspondingly small amounts are used.
  • the polymer concrete binder is preferably a resin selected from the group consisting of acrylate, epoxy, polyester, in particular an unsaturated polyester resin. The use of such polymers also has the advantage that the resulting concrete becomes more transparent, so that even below the outer layer lying pigment particles contribute to the luminous effect and thus to its increase.
  • Tranzparenzver housesr can be used in the concrete mix. This is preferably highly transparent quartz powder and / or
  • Fused silica and / or quartz glass and / or acrylate resin in an amount of 10 - 60% by weight. Depending on its suitability, this aggregate can replace the otherwise normally added normal sand.
  • Transparency enhancers increase the luminosity depending on the proportion in the mixture and the degree of transparency of the transparency enhancers used and, if appropriate, permit a reduction in the proportion of cement, since they also partly serve as binders, such as e.g. with the addition of acrylate resin.
  • color pigments can be added to the concrete in addition to the luminescent pigments. They already allow during the day a certain marking effect of the parts made with the concrete.
  • the basic mixture can be applied in all known types of concrete, including: site-mixed concrete, ready-mix concrete, shotcrete, underwater concrete, rolled concrete, spun concrete, vacuum concrete, construction concrete, screed concrete, aerated concrete, fiber concrete, mineral concrete, concrete concrete, self-compacting concrete, high-strength concrete Concrete, ultra-high-strength concrete, glass foam concrete, self-cleaning concrete, acid-resistant concrete (eg treated with phosphonic acid), complementary for translucent concrete, exposed concrete, asphalt concrete, chippings, polymer concrete, in-situ concrete, paper concrete.
  • site-mixed concrete ready-mix concrete, shotcrete, underwater concrete, rolled concrete, spun concrete, vacuum concrete, construction concrete, screed concrete, aerated concrete, fiber concrete, mineral concrete, concrete concrete, self-compacting concrete, high-strength concrete Concrete, ultra-high-strength concrete, glass foam concrete, self-cleaning concrete, acid-resistant concrete (eg treated with phosphonic acid), complementary for translucent concrete, exposed concrete
  • Exemplary uses for producing articles of bright concrete are building curtains; Cleaning material, in particular exterior plaster, Spritzbesch, socket plaster; screed; Prefabricated parts, in particular finishing steps / staircases, roofing concrete slabs, beams, pillars; Bricks, concrete furniture (e.g., benches, flower boxes, tables), swimming pool components (e.g., deckle curtains, launching blocks, jump equipment), balconies and balcony attachments, covers (e.g., manhole covers, outlet covers, bezel panel controls); Clinker; Enclosures (e.g., walls, pedestal walls); grouting; Surrounds of walls; partitions; Prefabricated components, in particular exterior walls, curbs, separating elements, supports; Roof structures and roof elements; Parts of and complete ramps, sidewalks and open spaces and traffic areas as well as their boundaries or complete markings; Parts of or whole obstacles including their markings; Slope securing stones (L stones, etc.); Grandstand safety devices, in particular markings of the safety-relevant escape routes or railings and / or other boundary boundaries;

  • the base concrete mixture from Example 2 is admixed with 23% by weight of white Portland cement.
  • Example 3 modified with the aid of acrylate.
  • the concrete thus obtained is filled in suitable molds and removed after setting, whereby luminous curbs are obtained.

  • the lighting duration can also be influenced here by the choice of the pigment.
  • the luminosity is increased by about 30% in direct comparison to the concrete mixture without Arcylat.
  • the polymer concrete produced in this way has better luminous properties in addition to the typical mechanical properties of a polymer concrete due to a lower proportion of non-translucent materials.
