Cans - lightweight concrete

description

Variant 08 03 2010

Manufacturing process for high heat insulating lightweight materials using recycled material (also suitable for manual production) and application of the same.

Numerous lightweight construction materials and construction methods are also known, whereby recycled products are also included as aggregates.

The production of the lightweight materials known per se requires expertise in their manufacture and requires costly investment.

The aim of the invention is to process cheapest aggregate material under the simplest conditions by means of locally inexpensive inexpensive binders to an extremely heat-insulating material and apply.

According to the invention this is solved as empty beverage cans e.g. Coke cans, beer cans or similar waste material can be blended with binders by hand or by conventional concrete mixers and filled into molds. Cardboard boxes can also be termed "lost formworks". serve.

In structural formwork interior sides (especially if these formworks are equipped with hinged walls), first of all, to increase the raw blocking resistance and then, as inner and outer facades, coating materials such as: rice straw, rice straw braiding,

Cereal straw, fabric mats made of various materials, cardboard material or other plates which may also have inwardly directed "anchor chocks ** or the like, before filling with lightweight concrete masses, be inserted.

Such, then after demoulding the building serving surface coverings, can also be oversized (seen laterally and height offset), inserted. Thus, the joints overlapping "reinforcements" can be formed after displacement of the structure.

Binders for the cohesion of lightweight concrete * Aggregates can be: clay paste, concrete milk, cement milk, Gfpsbrühe or other sticky and then solidifying masses.

Lehmschtämpe or clay paste (in water semi-liquid applied natural clay or the like) could serve as a particularly valuable binder insofar as in building materials can be produced in which no binders such as cement, gypsum or the like, are available. ≪ Prior to the addition of binders, said aluminum cans in the mixing drum could be encased with many types of adhesives (eg, epoxy resin emulsions - water-dissolved resins plus hardeners such as Epaxtn-Laromin or latex emulsions or other adhesives). Then then the actual binder can be added.

As the cheapest way of producing very well-insulated building structures, there is the possibility that as a cladding and binding agent of empty meta-doses during the driving process, first liquid clay sludge (omitting casing with any other means) and the second mixing stage in the further mixing process a rather thicker clay * water mixture is added.

As an example, it can be stated that usable cube compressive strengths can be achieved with a total of 15 to 30% proportion of natural clay mass of the mixing volume.

Provided that the building block dimensions (a building block for the construction of single-storey

Low-cost structures should be made of figurative building blocks with dimensions not smaller than 30 cm by 30 cm by 60 cm, or 20 cm by 20 cm by 40 cm, but rather with dimensions larger than these. 0 ί > «« ··· «♦ · • t • t« · «· • ♦

In the mixtures of such Baublockmassen fibers, or rice straws or rice straw mats or plastic fibers or mats may be inserted, so that the cube compressive strength and the flexural strength of such products can be substantially increased.

It is also advantageous according to the invention, if additives such. B. empty cans easily deformed before use as aggregate and the drinking openings are not closed, in shuttering boxes (also inserted by hand orderly) or added in mixing machines. This creates a "gearing" of these aggregates of lightweight concrete mass or an improvement in the internal cohesion of the mass. It may also be advantageous if the metal surfaces of the individual emptied metal cans are perforated by means of spiked rollers or the like. Also with this (due to the partial penetration of the binder, an increase in the internal strength of the lightweight concrete mass is achieved.

Also, the removal of adhesive labels on the waste cans can contribute to increasing the block material strengths.

Even if the previously inserted in formwork walls and / or soil funds such as straw mats, rice straw mats or similar products as well as braids of wire or fabric mats after removal of the building blocks from the molds not very firmly adhere to the block surfaces, this is not a defect, because only after Construction of the building, the inner or outer facade of the structures by means of plastic and then hardening coating mass "plastered" are. This is at the same time a Putzarmierung (as mentioned, for example by means of rice mats or the like.) Given this "reinforcement" is firmly pressed 1n the facade surface. This also increases the overall stability of the structure.

In order to save top floor constructions of small buildings (or emergency shelters after natural disasters) produced by means of concrete building material, it may be useful to have dome-shaped or pyramid-shaped

Small constructions by means of conically upwardly tapering allowed partial segment * elements which are uniformly formed to be formed. In this case, a Wasserableitende (straw mats or the like) or waterproof outer coating can take over the role of rain protection.

If cementitious facades * and / or interior coatings are used, the strength of such a coating can subsequently be significantly increased by spraying or brushing on the freshly applied facade coating colloidal solutions of sodium or potassium silicate (water glass).

This can also be applied when using Gipshältlger such coatings.

The binders for the building materials according to the invention may also be the EPS lightweight concrete (expanded polystyrene foam lightweight concrete) known per se. In this case, collected polystyrene foam packaging can then be comminuted with binders (rather liquid mixed) in a comminuted state (in particle sizes of a few millimeters down to piece sizes in the range of even approximately 5 cm to 10 cm). This can be extremely light > Building blocks are produced. However, are suitable accordingly

Machine equipment required.

It may even be advantageous to subject the aforementioned (mostly) comminuted polystyrene foam packaging parts to brief extreme heat to harden their fissured surfaces by calcination (sintering). As a result, their item-strength is significantly increased and on the other hand, by means of this "surface seal" 'the penetration of moisture into the interior of such lightweight concrete aggregates can be avoided. Thus, the excellent thermal insulation Elgenschaft such materials is maintained in the long term.

In conclusion, it should be noted that the "can concrete " on the one hand because of the low weight of the masses to be transported and on the other hand because mainly only cheapest aggregates are used, will be particularly successful in the vicinity of large cities. < 58/03 2010 01 10:18 [§E / E1t NR 9737] Ig008 09/03 2010 11:13 FAI 512 4075 ι

On the other hand, it is clear that the concrete concrete according to the invention in the vicinity of large cities, especially when natural clay or similar cheapest binders are available, opens up the possibility for countless people to build even with the least cost dwellings with extremely good thermal insulation properties.

In addition, the space required for garbage dumps is reduced. This also serves the common good. The transport costs for the disposal of the domestic waste is reduced by using the canned lightweight concrete.
