Description

PROCESSING FOR PRODUCTION OF GAS-CONCRETE

FROM SOLIDIFICATE

Description of the invention 1. FIELD THE INVENTION

The invention relates to treatment which defines the production of special types of concrete products, resulting from the processing of waste material, particularly those based on

hydrocarbons, which in addition to the structure of CH in the liquid state also contain other compounds and elements (Chlorine CI, Phosphor P, Sulfur S, Nitrogen N, heavy metals, etc.) for which these substances belong to the types of waste material and can be solidificate in order to obtain a dry hydrophobic powder.

The ultimate goal of getting solidificate the type of waste material is already in his rejection of further exploitation, and what can be achieved by further processing, and adequate preparation for a higher stage of his treatment.

According to international classification of patents, the invention falls within the range:

B BOl, B01 D; B03 B, B B04, B07 B, B F26, F28 F;

and in the area; E04 B (C03, C04), C E04, E04 F; B29 G21 G and F; G21 K.

2. TECHNICAL PROBLEM

It is well known that there are physical-chemical material processing methods that perform solidification materials, which can be obtained solidificate; comply with environmental regulations, quality suitable for disposal in municipal landfill.

The problem usually lies in the ways in meeting the criteria of physical characteristics such solidificate, because according to the regulations must not melt in water, spray on the air, and must be stored or packaged in a special kind of bag.

The author of this invention knows the current state of the art, based on the so far generated patents, such as P 940324, P 940325 (Croatia), EP 1109633 and others; the author is well known that solidificate still pose a problem, to difficulties in its further exploitation.

Cement demand a very high proportion of dry matter, even more than 90%, and also a smaller proportion of organic matter, even less than 50 mg/kg (TOC), while working fine grain solidificate need to install special devices for the dosing solidificate mixture of clinker.

The author is not aware that there is any procedure which would translate into solidificate silicate gas-concrete, forms, records and blocks which make up the properties and characteristics of particular types of concrete products that are distinguished by the characteristics of hydrophobic, low specific gravity, thermal insulating properties and high fire -resistance.

Chemical equilibrium for such treatment that would successfully achieve this, the author of this invention is known based on past research, it is very difficult because these solidificate not react with water, do not dissolve in water, floats on the surface, and its mixing in water, pelleting, consolidation and molding still has not been resolved in an economical manner.

3. STATE OF TECHNIK

Solidificate obtained by the procedure of processing (according to the report the authors of this invention: P940323 (Croatia) have characteristic physical and chemical properties that are substantially different from other species, especially because of the low density γ = 0,7-0,9 kg/m³, hydrophobic (coefficient of water-tightness: (κ = 10^"9 m/s), and fire flammability (flash point: 7 350 °C).

System solidificate (reported by the authors of this invention: P940326), which implies a protective barrier against harmful, poisonous, toxic and radioactive materials, located in a mobile tank, used only one of the many properties solidificate.

Production of such species solidificate requires special treatment program in which the principle of technological regime undergoes reaction with inserts that can be neutral, acid or alkali, and in that sense solidificate subordinate to such requirements.

Also, test fire solidificate (alone or in combination with other materials) showed that the burning solidificate with coal dust, which has a high sulfur content to achieve a new form of reducing sulfur compounds in the flue gas due to the merger with calcium and formation of calcium sulfate falling the bottom, creating new content in the ash.

Checks combustion solidificate in fluidization layer (with fluidization burning stoves) have proved to be a successful way of exploiting the internal solidificate calorific value (calorific value: Hd = 5 - 20 MJ/kg), because solidificate that is so technologically got in the process, assist the fire, kept calorific power of the boiler, and worked to preserve the walls and the surface area inside the furnace.

In the field of gas-silicate concrete which was obtained based on solidificate, as the author of this invention is known, there are no procedures in the world.

4. PRESENTATION OF THE ESSENCE INVENTIONS

Silica solidificate and conglomerates that are realized in the concrete mixture at the contact surface appears capsulate trapped gas (dry steam, air, C0₂), and the physics of free water bound to the cement firms around the creature to the formation of gas faster and better if it was used fast binding cement. When the resultant mixture, which still has the heat generated by solidification in a casting mold or pushing through the tunnel tube, air bubbles are captured and remain in the mixture because of their reactive power rapidly decreased due to differences in mass and pressure.

Well-formed gas-silicate concrete is characterized by the fact that drying does not appear in the bubbles on the surface, but uniform, smooth surface, which confirms that the relationships were well-placed accessories.

To mix with cement solidificate failed his physical condition should change in favor of increasing yield and consolidation with the silicates. One of these ways of using solidificate represented by the authors of this patent application the invention P20100325 A (Croatia). Getting the gas-silicate concrete products in a manner ad-mixing and some other types of additives and fillers in the cement mixture in which the receive better physical and mechanical properties, particularly in terms of design capability (forming), weight reduction, improved water-tightness, hydro-, thermo- and acoustic-insulation, fire-proof etc.

It is important to perform simultaneously in a time getting basic solidificate that gets straight to the course of primary treatment.

In this way achieves the low cost of production.

Solidificate recovered processing of various types of hydrocarbons have specific physical, chemical and mechanical properties in the construction of concrete mixtures affect its essential characteristics.

Such changes are important in terms of getting concrete mixtures that achieve:

- Environmental quality of content,

- Consistency of the material,

- Stability of the mixture,

- Sustainability of content,

- Performance of endurance,

- Resistance to atmospheric conditions,

- Resistance to the effects of other corrosive materials.

Such concrete products may contain different proportions of solidificate and silicate

conglomerates in the mixture, and best relations are selected on the basis of requests for their final application.

In this sense there is a difference between concrete products for special purposes, and the share solidificate subordinate their final purpose of exploitation.

As solidificate varied in their properties, which depend on the processing of the input material (moisture content in the input material, the greater or lesser solubility, content of heavy metal content in carbon, nitrogen, phosphorus, halogens, etc.), it comes with a different solidificate, which significantly affect the difference in the proportion of concrete mixture.

In large part of solidificate be very difficult to join in the concrete mixture with higher water content, because they emerge on the surface it is difficult to mixing in the standard types of concrete mixes. Therefore, it is necessary to know the technology of mixing concrete, additives and supplements, determine the speed of mixing, temperature of mixture, the order of adding the selected type of additives and fillers, sand (aggregate) and the amount of water and cement. This invention shown is a technological process by which the solidificate in progress to obtain a conglomerate of silicate added to cement (standard or fast-binding) and in terms of penetration of water vapor content, air and C0₂ mixture to achieve gas-concrete products. Often, in terms of improving the mechanical and physical properties of finished products, siliceous conglomerate, in addition to fast-sticks types of cement, pass the: sand, gravel, solidificate from the processing of asbestos and other types of fillers that stronger and better connect the mixture (or textile, jute or polyethylene net, etc.).

Special features such concrete products enhance the technical and technological characteristics of common types of concrete which, in addition to environmental and other realize exceptional value, especially because:

- Low prices of finished products,

- Less unit weight of the product,

- Increased hydro-insulation properties,

- Increased thermal insulation properties,

- Elevated acoustic-insulation properties.

Often mixing solidificate in concrete mixture completely restricted by its content and only empirical methods leads to the most favorable relationship.

To achieve adequate quality of these kinds of concrete, but without achieving the rationality of production and lower the price of the finished product it is necessary to perform several experiments.

Solidificate in the concrete mixture significantly reduce certain mechanical properties of concrete, and these have less strength, and therefore less capacity, and can not be exploited by the responsible species (bridging beams, bearing walls, columns, support, etc.).

Getting a bigger load of concrete products would require significant incorporation of reinforcing elements (polyethylene or a jute mesh) customary at the time forming.

7. METHOD OF APPLICATION OF INVENTIONS

In addition solidificate concrete mixture used empirically determined solidificate ingredients that may be in it, and to achieve the required properties. When small additions of solidificate (<5%) the concrete after curing will have approximately the same properties as that solidificate were not added. The difference will constitute a smaller force of the break in testing fracture (Monitor test tubes or blocks 15x15 cm). When a larger share of solidificate (> 12.5%) concrete will change color with the significant reduction in capacity and power failure. With the additions solidificate 12.5 to 23.5%, and in which concrete without reinforcement will still have sufficient strength for use for certain purposes in construction (drywall, sandwich-wall, house fences, etc.) in most of the properties will increase hydro-thermal and acoustic-insulation, where the unit weight of concrete products will be reduced by about 15%.

With the additions of solidificate 23.5 to 43.5%, and in which concrete will continue to be of sufficient strength for use in less responsible in civil engineering purposes (garden paths, pavements, overlays, etc.) solidificate will affect markedly reduce the unit density (> 30%), and hydro-, thermal- and acoustic-insulation would be considerably increased. Load capacity of concrete products such limits their use are they if not installed reinforcement of static account. For concrete products in which no substantial payload, which will be used in a less responsible use (designed models, media channels, etc.) share of solidificate in the mixture can be very high (> 50%). Strengthening the structure of such gas-concrete format can be successfully performed with additions based on the reinforcement fibers, synthetic resin, solidificate obtained by asbestos, which also reduces weight, improves the mechanical properties and impact on strength and durability of concrete. The quality of a concrete product that is built on the basis of solidificate from the processing of hydrocarbons depends on a number of mutually related technical and technological factors, among which in particular:

- Type of solidificate (source formation, chemical composition, physical properties),

- The type of sand (well, granulation, moisture content, density),

- Type of Cement (source, brand concrete MB)

- The amount of additives, sand and cement (the ratio, the order of addition)

- The percentage of water,

- Stabilization of the concrete mixture,

- Types of material for connecting concrete mixture,

- The speed of production of concrete products, etc. The addition of additives and water, at the expense of a lesser amount of water results in better design and flow of molding concrete mixture, given the sharp edges, more accurate form and the required format products, but what the limits getting surely concrete shape with respect to mechanical properties. It is therefore necessary in the production of shapes gradually add water and spray, but always as much as the mixture meets the edge of dry and wet conditions.

As each product so it will be a concrete product obtained on the basis of solidificate need to examine the quality, performance, features and other characteristics, in particular:

- An ecological study (chemical composition)

- Physical properties (electrical conductivity, hydro-, thermal-, acoustic-insulation),

- Mechanical properties (strength, hardness, capacity)

- Durability properties, stability, etc.

The simplest form of exploitation of concrete products obtained on the basis of solidificate treatment sludge from the one where does not come to the fore the importance of responsible mechanical function (payload, fracture strength, angular stresses, etc.).

When concrete products in which the composition of the solidificate higher (> 35%), the best application would be in terms of production elements laid on a firm basis (e.g. noon garden slabs, paths, overlay and cladding). Such concrete products would be examined at:

- Chemical composition (environmental cleanliness)

- Mechanical properties (strength).

In this sense appears tabular overview of the data that characterize the conditioned concrete mixture and the best way of utilizing the obtained concrete products.

Table Data

Additives and water is the share of the content of special types of additives (synthetic fibers), molecular and. required water for mixing, which remains as a conditioned moisture product prior to drying air, while the final chemical analysis obtained on the basis of laboratory tests.

According to the method of mixing additives and application of the final product were determined and reasonably necessary mechanical properties of concrete products, and in this sense, investigations relating to:

- The speed of drying (in the process of manufacture)

- Drying the air (during the aging process and application)

- Maintaining consistency (durability, stability),

- Wear (durability in use).

The final concrete mixture with a larger share of the solidificate suitable for capping and coating, especially in terms of obtaining a waterproofing layer or increased thermal insulation and acoustic-insulating properties of concrete surfaces.

In this sense, certain types of mixtures (poor concrete) in which the solidificate and additives in high content (> 45%) the same compound will be suitable for certain types of plaster (plaster) for external and internal protection of the walls. It increased the calcium content of such materials will have high sticky the property done.
