Definitions
- the invention relates to a lightweight concrete, which consists of glass foam granules at least one grain fraction with a binder, preferably cement, bitumen or synthetic resin. Furthermore, the invention also relates to a method for producing lightweight concrete.
- Fuller curve is generally state of the art and can be found in the relevant literature and the corresponding standards.
- a disadvantage of the above-mentioned lightweight concrete types and their production is mainly the production of fine fraction, since this must be carried out with complex mechanical processes.
- Another serious disadvantage is the fact that in the production of fine fraction heavy environmental pollution can be avoided only by the most expensive precautions. It is therefore an object of the invention to provide a lightweight concrete of the type cited, which on the one hand avoids the above disadvantages and on the other hand can be produced efficiently and economically.
- the lightweight concrete according to the invention is characterized in that the glass foam granules have a grain fraction at least the size 2, preferably at least the size 4, and that as fine fraction, a filler material having a grain fraction to 4, preferably to 2, and a volume fraction of
- Lightweight concrete from 0.1 to 50%, preferably from 0.1 to 25%.
- the lightweight concrete according to the invention it is now possible to produce a building material for optimal economic aspects, which also meets the corresponding requirements, be it the relevant standards or other legal provisions, with certainty.
- prefabricated elements such as lightweight components, monolithic walls or structural concrete, but also bricks, in particular hollow bricks, attachment elements, soundproofing elements or ready-mixed concrete or in-situ concrete can be produced from the lightweight concrete according to the invention.
- the lightweight concrete according to the invention for the various applications is made of glass foam granules, according to the required grain size and Komge Stahlges and a binder or a filler material for the desired properties.
- filler material for the lightweight concrete according to the invention in particular a commercially available, commercially available product is used. According to the Requirements for the lightweight concrete according to the invention is selected in the filler material palette. Corresponding examples are given below.
- the lightweight concrete produced in this way can be produced with economic outlay in accordance with its intended use.
- the proportion of glass foam granules is a maximum of 75%.
- Organic glass spheres preferably with a sintered surface used.
- Such a filler material has a lower weight than the fine fraction of the glass foam granules, whereby an extremely lightweight concrete is produced.
- expanded clay sand is used as filler material.
- this filler material the compressive strength of the lightweight concrete according to the invention thus produced is increased.
- the use of expanded clay sand allows moisture storage in lightweight concrete.
- pumice is used as filler material.
- This naturally occurring filler material blends seamlessly into today's trend-setting bio-philosophy of living and also allows in combination with glass foam granules good thermal insulation and sufficient compressive strength.
- natural sand or fly ash is used as filler material.
- This filler material is also trendy the bio-philosophy and has the high specific gravity high compressive strength of lightweight concrete.
- the filler material used is preferably comminuted, expanded and / or extruded polystyrene. As a result, a very lightweight and highly insulating lightweight concrete is produced.
- perlites are used as the filler material.
- This filler material is not only very light, but its characteristics are a compromise between expanded clay sand and blown glass beads.
- hemp fibers are used as filler material.
- Hemp fibers serve as a reinforcement, similar to a reinforcement, and increase the flexural and compressive strength.
- the hemp fibers serve as insulation additives.
- they serve for water storage and moisture buffering, so that a particularly favorable living climate is achieved.
- Hemp is also one of the few natural fibers that are resistant to microbial attack and very much in line with today's ecological trend.
- As a secondary effect for hemp fibers it can be seen that the cultivation of this natural product promotes agriculture and in the course of its growth stores three times as much nitrogen oxides as conventional plants. This fertilization of the soil for subsequent plants is practically no longer necessary.
- the lightweight concrete has a closed grain structure.
- a lightweight concrete with a closed KomgeHoge is needed especially in the production of monolithic walls.
- such a lightweight concrete can also be used for precast parts of any kind or construction elements, for example, scarf protection elements.
- an air entraining agent is added. As a result, a lightweight concrete can be produced economically, which is light and yet has a completely closed surface.
- the lightweight concrete has an open or heap-porous Komge Suite.
- Such lightweight concrete is used primarily in the production of bricks, especially hollow bricks, use.
- the lightweight concrete is a
- Foaming agent added. This foaming agent fills the cavities between the individual glass foam granules. Since the specific gravity of this foaming agent is far below the specific weight of a glass foam granulate fine fraction, an extremely lightweight concrete is achieved. In addition, both very high static requirements, as well as very high heat-insulating parts, even in exposed concrete quality, can be realized cost-effectively.
- a starch ether is added to the lightweight concrete.
- a starch ether in the dosage of, for example, 0.025 to 0.5% by weight of the binder, for example cement, in particular segregation during processing is avoided. This is particularly advantageous when processing masses with different grain densities, such as glass foam granules and polystyrene or sand.
- the starch ether acts like an adhesive, which glides past the individual grains and thus prevents segregation.
- the object of the invention is also to provide an extremely economical process for the production of lightweight concrete.
- the inventive method is characterized in that the glass foam granules exclusively from a mixture of Glasmeh! and silicon carbide is prepared, wherein in a conventional manner, the glass powder and the silicon carbide are dry mixed and the mixture is subsequently blown in a thermal process.
- the glass foam sheets produced in the thermal process are treated shock-like immediately after the thermal process with a gaseous or liquid coolant.
- a gaseous or liquid coolant be it air, water or steam, for example, can directly influence the breaking of the material leaving the blast furnace.
- the hot material with the coolant for example in the form of a jet or flat, treated.
- the desired particle size of the refracting glass foam granules can be achieved by far.
- the glass foam plates produced in the thermal process are comminuted with a mechanical device, for example a spiked roller with cutting tools.
- a mechanical device for example a spiked roller with cutting tools.
- the spiked roller arranged directly or near the furnace outlet could move at the circumferential speed of the material ejection.
- a refraction of the glass foam plate is carried out in accordance with a sieve curve, which is deviating, especially in the smaller grain fractions strongly different, the Fuller sieve curve.
- a sieve curve is sought, which in some areas of the Fuller curve aware differs.
- the glass foam granules are coated or flooded with a high-strength, high-viscosity binder, for example by immersion or flooding.
- This self-supporting soundproofing elements can be produced.
- Another advantage of this lightweight concrete lies in an above-average absorption behavior and the ability to carry self-supporting elements.
- the lightweight concrete is mixed with a filler material, in particular a high-strength, high-viscosity binder.
- a filler material in particular a high-strength, high-viscosity binder.
- the lightweight concrete according to the invention produced by the process according to the invention, can very well fulfill the European Standard EN 13055-1 or the ⁇ NORM B 4200 Part 1 1.
