Definitions
- the invention relates to a method for producing a lightweight building material, in which, as an additive, expanded particles with a hardening binder containing cement, e.g. Cement paste to be bound.
- a hardening binder containing cement e.g. Cement paste to be bound.
- EPS expanded polystyrene
- the object of the invention is therefore to provide a method for producing a lightweight building material, in which additives are used which are not produced in industrial production but come from natural cultivation and only require further treatment.
- Another object of the invention is to carry out the production of the aggregates with the least possible environmental impact and to guarantee the later problem-free disposal of the building material.
- expanded plant material such as expanded corn, expanded rice, expanded potato chips or the like, is used as the additive.
- the additives are treated with a protective agent against bacterial and pest infestation before coating with cement paste.
- a particularly effective treatment for protecting and solidifying the additives is obtained if the additives are soaked with sodium or potassium water glass before coating with cement paste.
- the aggregates are coated with a mixture of water glass and water, e.g. one part water and two parts water glass.
- Another feature of a method according to the invention can be that the additives, optionally after a pretreatment with a protective agent, are mixed with water glass or a mixture containing water glass, and powdered cement is added to this mixture in the wet state and mixed with it, after which the dry, with cement coated particles, optionally after storage, are bound with cement paste.
- a cement stone crust forms after a short time when the treated aggregates come into contact with cement paste, so that the mixed goods can be filled into containers, e.g. Sacks that are made available for transport to the construction site.
- the lightweight concrete can be produced on site.
- a further variant of the invention can consist in that the particles are mixed again with water glass or a mixture containing water glass after a first coating with cement and powdered cement is added to this mixture in the wet state and mixed with it, after which the dry, with Cement-coated particles, optionally after storage, are bound with cement paste.
- This aggregate coated in this way now has a hard cement stone shell, through which the lightweight concrete is very suitable as a filler for cavities which are to be insulated.
- Another object of the invention is to provide a method for producing plate-shaped parts for agricultural purposes, such as vole protection plates.
- the invention which follows describes a process for the production of a lightweight building material, in which, as an additive, expanded particles with a hardening binder containing cement, e.g. Cement paste, bound, relates, explained in detail using exemplary embodiments.
- a hardening binder containing cement e.g. Cement paste
- expanded plant material such as expanded corn (popcorn), expanded rice (puffed rice), expanded potato chips or the like
- expanded corn popcorn
- expanded rice expanded rice
- expanded potato chips or the like
- These expanded particles e.g. in grain sizes up to 20 mm and above, are bonded with glue, creating solid structures.
- Cement glues, mixtures of cement and water, are preferably used as glues.
- the bulk density of these structures can range from 0.10 kg per liter to 0.5 kg per liter and above.
- the additives can be treated with a protective agent against bacterial and pest infestation before coating with cement paste.
- the impurities can be protected and solidified by impregnating them with cement glue with soda water glass or potassium water glass.
- a further variant of the process according to the invention for the production of lightweight building materials consists of the individual vegetable additives, optionally after pretreatment with a protective agent, before coating with cement paste, in each case with water glass or a mixture of water glass and water, for example 1 part of water and two parts of water glass or - depending on the moisture content of the grains - other mixing ratios are encased in the mixer trough, whereby powdered cement can be added in the same mixing process.
- the cement portion that comes into contact with water glass solidifies in a matter of seconds or minutes and forms a cement stone crust on the particle surface of the aggregates.
- the expanded vegetable particles now coated in this way can now be filled into containers, e.g. sacks, immediately after leaving the mixing trough, with additives such as lime, cement or stone powder and / or dispersion powder or the like or sand etc. being able to form ready-mixed mortar. This has made it possible that these sacks can later be formed into compact lightweight materials by binding with cement paste in any mixer - including free-fall mixers - e.g.
- precast elements for the greening and consolidation of steep slopes and slope retaining walls, as well as for pillar-like supporting elements can be produced with these lightweight building materials.
- panels according to the invention made of lightweight building materials, which are formed from bound expanded vegetable materials (EPF fabrics), can be designed such that holes are arranged in the EPF fabric panels, which are filled with humus Humus plant seedlings or seedlings can grow. If the holes in the plates go completely through the plates, fixed grids can be arranged at least in sections on the underside of the plates, which prevent the voles from attacking the plant roots.
- the vole protection plates designed in this way can be produced, for example, in handy formats, for example with the dimensions 40 cm ⁇ 20 cm or the like, or in lengths from 0.5 m to 3 m.
- vole protection plates or shading plates also have the advantages that the floor surface cannot dry out so quickly and that the moisture is retained. Likewise, floor cooling is no longer possible as quickly as without the shading plates or vole protection plates.
- Another method according to the invention for the production of lightweight building materials can consist in moistening particles of the expanded plant additives, such as expanded maize or rice or potato material, in a mixer with water glass or a mixture of water and water glass and then applying powdered cement in the same mixing process , after which water and / or water glass is again brought into the mixing trough with the moist mixture in order to carry out another covering with cement.
- the EPF grain is particularly heavily coated and solidified.
- This coated EPF grain now has a hard cement stone shell. As a result, the grain now becomes a filler for cavities which are to be thermally insulated.
- the cement-coated particles can be bonded with cement paste. It can also be used as a substructure for Screeds are formed - whereby this heavily coated EPF grain does not have to be bound with cement glue or other glues, so that no moisture is incorporated.
- Such heavily coated grains can also consist of EPS (expanded polystyrene foam) grains.
- Another method according to the invention is that the EPF substances or EPS concretes mentioned can be cured by subsequently spraying or soaking the surfaces of the bodies, components or coatings or coverings with water glass or mixtures of water with water glass.
- the partial surface is not only significantly solidified, but also made fireproof, although the mass itself is a non-combustible building material belonging to Brandidasse A.
