Abstract

Building material, e.g. for road surfacing, comprises a mixture of bitumen and/or cement and sand and cut-up residues from the prepn. of tyres and/or glass in proportion of 10-80% of the mixture.

Description

Building material, in particular for road surfaces, building blocks, underlay and plastering. The present invention relates to a building material, in particular Door pavement, building blocks, underlay and plaster, consisting of a mixture made of bitumen and / or cement and sand.

The building materials used so far for the production of road surfaces Building blocks and sub-floors, as well as for carrying out plastering work, can not satisfying in every respect. With many well-known building materials, the Strength and insulation properties leave a lot to be desired. Also, many have known Building materials have certain properties, which, for example, in road construction as a disadvantage. This is particularly true with regard to the water repellency for certain building materials used for road construction.

In addition, known building materials are poor or at all not suitable to be used for plastering work mixed with cips or mortar to become. In addition, the production of the building materials is often expensive, as a result the raw materials used or the complicated ones required for production Devices and methods.

The present invention aims to create a building material which does not have the above-mentioned disadvantages of known building materials and moreover is cheaper to manufacture than building materials known per se.

According to the invention, this is the one mentioned at the beginning for a building material Art achieved by blending leftovers from this mixture Pneus and / or glass are attached, the proportion of these processed remains is between 10 and 80% of the total mixing ratio, The invention is based on the knowledge that for the manufacture of certain oxygen starting materials Can be used for which no purpose has yet been found is. Such raw materials belonging to the waste are also useful for environmental protection t always an acute danger, since they are either kept in the open, or then with Unsuitable means are destroyed, which in turn contributes to environmental pollution. Such materials can be rubber and glass. Indeed, surrendered Today there are huge amounts of waste of such materials, like all, wrecked Pnsus of all types, with or without steel inserts, as well as all kinds of glass waste.

It has now been found that it is precisely these waste materials as Component result in a building material that has certain properties that gerado for the above-mentioned uses has not insignificant advantages. In addition becomes the building material in his through the mentioned use of these waste materials Production cheaper, especially since it is done with the usual, known, simple processes can be produced. In addition, the. Fact that old, until now material that is difficult to remove can be used, a not insignificant one Contribution in terms of environmental protection made, which is not at the present time should be sufficiently appreciated.

With the aid of a few exemplary embodiments, the inventive Building material, or its production, are explained in more detail.

The processing of the materials is done in such a way that old ones Tires are cut by machine, in the size of the ru used Stone alleys. These cuttings can, for example, be 1 by 1.5 mm in size or 3 to 10 mm by 5 to 10 cm. These sizes are particularly suitable to create a substructure for road works. In addition, pieces of 2 to 8 mm2 are cut, which is particularly useful for fine pavement in road construction but also suitable for sub-floors or for the production of building blocks.

When using glass, the material is processed in such a way that the glass either up to a grain of sand (glass sand) or but fine chippings are processed.

In this state, prepared materials called dip form the Additive for the production of bitumen, which, as already mentioned, is can be used to create road surfaces, or in general in the construction sector Can be used.

For the substructure of a road, according to one embodiment coarse cuttings of tires and broken glass used the above treatment process have gone through. These materials are mixed with bitumen and gravel, whereby the mixing ratio can have the following values, for example: Ditumen approx 5% tire and glass 50 ffi gravel 45% These values can of course depend on Use can be varied as required.

For a fine road surface or for the creation of citizen doughs or parking spaces, the mixing ratio can have the following values: bitumen approx. 5% pneumatic and glass sand 80% chippings 15% In this case, special Use the tires to cut into small pieces and the glass waste to glass sand processed.

Can be used for the manufacture of building blocks from different materials the waste materials used, such as tire and glass scraps, in a desired, known ratio mixed with cement.

To carry out mortar work, such as plastering work, ru Glass sand uses recycled glass, mortar and sand, with the mix ratio 1 t 3 (1 part glass sand and 2 parts mortar and sand).

The mixing ratio in the solid concrete preparation can have a value from 1: 3 or 2 to 2.

As a further example of a use of the building material according to the invention a prefabricated underlay should be mentioned here. The prefabricated panels, which have a size of, for example, 50 by 50 cm and are made from a mixture consisting of tire residue and mortar, are layered in bitumen on a boton floor laid or glued 0 These panels are then sanded with the help of a machine, the surface of these plates being such that immediately after this grinding process with the laying of parquet boards or a tension memory can be started. With the previously known method, had to Wait four weeks and more until the prepared surface is up to the finished cover (Parkatt or carpet) could be covered. In addition, the fabricated panels made from a mixture of tire residue and mortar lighter in weight than conventional type panels. In the. Did, the weight of these new panels is 1100 kg / m3, while that of the conventional Panels is at least 1800 kg / m3.

Can also be used to manufacture pipes or so-called centrifugal tubes serve the building material according to the invention. For this purpose a mixture sus Classand or Glass splinters with mortar, with 10 to 50% glass or glass sand and the rest mortar is used. Here, too, the mixing ratios can vary depending on the circumstances can be varied greatly.

As a result of the water-repellent properties of the proposed Building material, this is especially predestined for road and building construction. A pavement made with the building material mentioned stops according to the results of experiments carried out at least 10 times longer than one with a conventional one Covering. In winter, this new road surface is also much more resistant to knowledge due to the added rubber there is a favorable thermal effect, which largely prevented street shops as a result of the frost.

Building blocks that are made with the proposed building material, have a very high strength, are almost indivisible and practical unbreakable.

They also have excellent insulation values and are water-repellent.

Finally, the advantages mentioned are the lower production price to be added, which is due to the use of sufficient waste material must inevitably result.

Since work orders in the construction sector, especially road construction and House construction, almost unlimited, represents use and recovery of the above-mentioned pneumatic and glass waste for the production of building materials is not to be underestimated Contribution to environmental protection that is topical today.
