Definitions

  • the invention relates to a method for producing components, in particular building boards and mixtures, a thermally treated mixture of combustion residues, water-containing substances and CaO being used as the binder.
  • non-load-bearing partitions made from renewable raw materials, such as flax, hemp, straw or the like, and gypsum (DE-GM 297 14 805, 296 20 751). All of these panels and partitions have the lack of exclusive usability already described for the gypsum plasterboard for interior construction. Furthermore, their strength and elasticity values are very low, so that the areas of application are also severely restricted there.
  • Cement, ⁇ - and ⁇ -hemihydrate made of natural gypsum or REA gypsum are known as binders for building boards.
  • a process for the production of a binder is known for the immobilization of pollutants, the starting materials for the storage components being mixed from combustion residues, water-containing substances and CaO and subjected to a special thermal treatment (DE 197 19 684). The use of this product in building materials is not described in detail.
  • foam glass products with granular properties are produced from fly dust or fly ash and alkali silicates, whereby fly dust and alkali silicate or alkali hydroxide solutions and water are mixed, the mixture is hardened by heating for several hours at up to 100 ° C, which cooled Crushed mass, a fraction of ⁇ 1, 6 and> 3, 15 mm sieved and the product obtained is inflated by renewed heat treatment at 150-300 ° C (25-35 minutes) (DE-OS 31 36 888).
  • the corresponding product can be used for insulation purposes.
  • the manufacturing process shows that the granulate produced in such a complex manner can only be produced using large amounts of energy and technology, which undoubtedly has to have an impact on its price.
  • DE-OS 43 42 996 discloses the use of foam glass granulate made from recycled glass as a lightweight aggregate in cement-bound lightweight mortars and concretes and thermal insulation plasters.
  • the invention has for its object to produce light and stable components and / or mixtures that can be used in a variety of ways for interior and exterior construction, consist almost exclusively of residues and can be produced inexpensively. This is achieved in accordance with the invention in that this binder is mixed with known foam formers or with granules or similar porous materials and water foamed from recycled waste glass, if necessary subsequently pressed into molds and brought to hardening.
  • Lignite, hard coal, fluidized bed filter ash can be considered as combustion residues.
  • the water-containing substances can be water or liquids or substances containing water of crystallization and partially dewatered gypsum dihydrate.
  • the foaming agent is used in an amount of 0.3-3% by mass, based on the total mixture.
  • the proportion of binder glue is between 5 - 60 M%, depending on the intended use of the product, with a strong heat-insulating use with subordinate load-bearing capacity in the lower area and a less heat-insulating use with increased load-bearing capacity in the upper area.
  • the foaming agent is first added to the water or simultaneously to the mixer. An increased mixing time (at least 120 seconds) is required to generate the necessary amount of air pores.
  • the binder is produced with a proportion of 20-95% by volume, preferably 50-80% by volume of foam glass granulate and 80-5% by volume, preferably 50-20% by volume, of binder. It is particularly advantageous that the binder used can be pretreated specifically for the intended use during manufacture, due to its special residence time and graduated temperature treatment, so that the binder and the foamed granulate are always optimally matched to one another and to the intended use. In terms of cost, the combination of the binder used, which is to be produced entirely from residual materials, with the foamed granules, which in turn can be produced exclusively from recycled materials, results in an almost ideal connection. This is all the more so since only granules are used that are blown and manufactured without high-temperature treatment.
  • Foamed components for thermal insulation walls are to be manufactured.
  • the mixture is placed in suitable molds which correspond to the desired product size, e.g. B. in rectangular shapes 12 x 30 x 60 cm. After about 2 hours, the structures are removed and stored dry until they are installed.
  • suitable molds which correspond to the desired product size, e.g. B. in rectangular shapes 12 x 30 x 60 cm.

Abstract

L'invention concerne un procédé qui permet de fabriquer des éléments de construction, notamment des panneaux muraux et des mélanges, selon lequel on utilise comme liant un mélange, traité par la chaleur, de résidus de combustion, de substances aqueuses et de CaO. L'invention a pour but de fabriquer des éléments de construction et/ou des mélanges légers et stables que l'on puisse utiliser de diverses manières pour les travaux de finition intérieurs et extérieurs, et qui soient constitués presque uniquement de résidus et fabriqués à faible coût. A cet effet, on mélange ce liant avec des moussants connus, avec des granulés moussés de verre perdu recyclé ou avec d'autres matériaux poreux similaires et de l'eau, puis éventuellement on le presse dans des moules et on le fait durcir.
