Description

 Additive composition for building materials based on minerals

Field of the invention:

The invention relates to an additive composition and the use of the additive composition in building materials based on minerals, wherein the additive composition in building materials exerts a stabilizing, pore-forming effect and further ensures good flowability of the building material. The invention further relates to a method for producing a building material according to the invention and the building material itself. Furthermore, the invention relates to components which contain the building material according to the invention.

State of the art:

For thousands of years, the "elements" of earth, water, fire and air have created a building material of incomparable functionality and attractiveness.The solid building material concrete guarantees a wear-resistant building substance.Concrete structures also have a service life of well over 100 years Concretes have one of the slightest changes in the shape of all building materials, eg static load, heat or cold influences, making concrete structures particularly durable.

Concretes and mortars have good thermal insulation due to their fine pore and capillary structure. Concrete can also meet the requirements of the low-energy house standard, including with regard to the German Energy Saving Ordinance (EnEV). It should be noted that the heating energy requirement of a house does not depend solely on the U-value (heat transfer coefficient in WMi ² K) of the wall, but is an interplay of many factors.

Concrete buildings have very good soundproofing properties. The sound insulation of solid exterior concrete walls is at least 45 - 70 decibels (dB) well above the insulation of windows and windows Lightweight constructions and, for special concretes, eg with stabilizing plasticizers, the requirement for the increased sound insulation of 55 dB, eg for apartment partition walls, are fulfilled even with a 20 cm thick wall.

Concretes also have very good fire protection properties and belong to the fire resistance class F 90, whereby even thin walls ensure for at least 1, 5 hours that a concrete building stands still. A massive building increases the chance many times to save yourself and your fellow humans unharmed. Furthermore, a building made with concrete does not give off any toxic fumes in the event of fire. Concrete building materials significantly exceed the applicable fire protection requirements.

Concrete-made components are classified into high compressive strength classes. This means additional security for builders and architects. Shrinkage and expansion due to cold, heat or moisture and thus cracking of the walls occur to a much lesser extent in concrete-produced components. Concrete-made components have excellent dimensional stability. The static advantages of a solid structure ultimately also contribute to the other important properties such as wind-tightness, sound insulation or moisture protection.

An object made of concrete components contributes to a pleasant indoor climate. As a diffusion-open building material, concretes have the lowest equilibrium moisture content of all wall building materials. You can absorb the moisture and release it only during the next weather change. The wall surfaces remain dry in every season and thus ensure a pleasant indoor climate. Concrete walls also look like natural air conditioning. Temperature fluctuations are compensated by the supply or release of heat. In winter, the building remains relatively warm, in summer correspondingly cool. Concretes are also advantageous from a medical point of view since no toxins are present, no harmful exhalations take place, such concretes possessing minimal radiation exhalation compared to other building materials. Furthermore, concretes have a high resistance to corrosion and decay toxicologically harmless and antiallergic even in case of direct skin and mouth contact.

Massive structures are by design airtight. The heat energy can not escape through joints or cracks in the house. Massive structures remain permanently airtight, because the walls show little or no change in shape of the components which could cause subsequent leaks. Solid masonry therefore does not require sealing foils, i. Long-term critical zones such as joints and connections of the foils are eliminated from the outset. An airtight house is not only a guarantee for the long-term preservation of thermal insulation but also for the prevention of structural damage due to damp components, because "leaky" places lead to the formation of condensation water ,

In a massive structure, mold or other harmful influences have less chance of damaging the building fabric. The solid construction and long-term stable construction quality require only a small maintenance effort.

Concrete building materials are also advantageous from an economic point of view, on the one hand with regard to low production costs, and on the other hand also with regard to low maintenance costs.

Concrete building materials are products of the natural components fire, water, air and earth (clay / sand / gravel). They are characterized by

• good thermal insulation properties

• Environmentally friendly raw material extraction and energy-saving production • Reduction of pollutant emissions

• short transport routes during production and delivery by using domestic raw materials.

By recultivation of raw material extraction pits arise

Recreational areas or valuable biotopes with species-rich fauna and flora. Mineral building materials can be easily used again, eg as a supplement in the production of new mineral building materials, as a substructure material in road construction, for noise barriers and the like.

Despite these advantages, in concrete these very properties still need to be improved, i. they need to be improved in terms of durability / longevity, thermal insulation, sound insulation, fire protection, indoor climate, statics and airtightness.

The object of the present invention is thus to overcome the disadvantages of concrete building materials according to the prior art in terms of durability / longevity, thermal protection, sound insulation, fire protection, indoor climate, statics and airtightness without impairing the compressive strength.

Detailed description of the invention:

Air pore agents are used to create closed micro air pores in concrete and mortar. The additive composition comprises from 5 to 50% by weight, preferably from 10 to 45% by weight, more preferably from 15 to 40% by weight of at least one air-entraining agent. The air-entraining agent for the additive composition according to the invention is preferably selected from a group comprising alpha-olefinsulfonates, alkylbenzene sulfates, alkali metal sulfate, Na salts of alkylnaphthalenesulfonate, naphthalene derivatives and / or sodium lauryl sulfate.

The additive composition further comprises from 5 to 50% by weight, preferably from 10 to 45% by weight, more preferably from 15 to 40% by weight of at least one thickener. The thickener is preferably selected from methylcellulose (MC), methylhydroxyethylcellulose (MHEC),

Methyl hydroxypropyl cellulose (MHPC), hydroxyethyl cellulose (HEC) and / or polyacrylamide. As a further component, the additive composition comprises 10 to 60% by weight, preferably 15 to 55% by weight, particularly preferably more than 35 and up to 50% by weight of at least one liquefier. The liquefier is preferably selected from a group comprising melamine resin derivatives, polycarboxylate and / or lignin sulfonate.

As yet another component, the additive composition comprises from 5 to 40% by weight, preferably from 10 to 35% by weight, more preferably from 15 to 30% by weight of at least one flow agent, wherein the flow agent is selected from a group comprising melamine resin sulfonates, polycarboxylate ethers and / or naphthalenesulfonates. The naphthalenesulfonates are based on unsaturated mono- and / or dicarboxylic acid derivatives, Cio ~ Ci ₅ -Oxyalkylenglycol- Alkenyiethem and / or oxyalkylene glycol-Alkenylestem.

Finally, the additive composition also comprises 5 to 50 wt .-%, preferably 10 to 45 wt .-%, particularly preferably from 15 to 40 wt .-% of at least one stabilizer, wherein the stabilizer from the group comprising biopolymers, polysaccharides, glycolic acid and / or bentonite is selected.

The components mentioned, ie air pore agents, thickeners, plasticizers, flow agents and stabilizers can be used in powdery, dry or liquid (dissolved) form. Preferred carrier material for the liquid form is water.

In addition, the additive composition may still be diluted with an inert (powder) or H ₂ O support material.

The additive composition is characterized in that it has a stabilizing and pore-forming effect on a building material composition. In contrast to the prior art, the additive composition causes no pore formation by gas evolution (ie peat formation on the pile side). The formation of the pores is explained in more detail in the section for the production of a building material. Further advantages of the additive composition according to the invention are a reduction of the water / cement value (liquefaction), improvement of the flow effect, a reduction of shrinkage, improved hydrophobization and better dispersion.

The additive composition may comprise as further component 5 to 40% by weight, preferably 10 to 35% by weight, particularly preferably 15 to 30% by weight of an accelerating agent. The accelerator agent is usually calcium salen aluminate, calcium chloride, arene and alkyl sulfonic acids and their salts, preferably alkali metal salts. Other accelerator means known in the art may also be used.

The additive composition may comprise, as still another component, 5 to 40% by weight, preferably 10 to 35% by weight, more preferably 15 to 30% by weight of a shrinkage reducing agent for minimizing shrinkage cracks. The shrinkage reducing agent is preferably selected from glycol combinations and / or cycloaliphatic mixtures and / or a synergistic mixture of an alkyl ether-oxyalkylene adduct and short-chain oxyalkylene glycols. Furthermore, alkanediols with terminal OH groups can be added as an additive for reducing shrinkage in cement-bound building materials. The additional amounts are between 0.2 and 10 wt .-% based on the cement. Also particularly suitable is 2,2-dimethylpropane-1,3-diol. Esters of sulfonic acid, phosphoric acid and phthalic acid can also be used as shrinkage reducers. Also preferred are trioctyl phosphate, tricresyl phosphate, triphenyl phosphate, diisooctyl phthalate and phenylalkyl sulfonates (alkyl radicals having 1-10 C atoms). Also preferred is a mixture of dipropylene glycol tert-butyl ether, dipropylene glycol and a small amount of betaine (cocoamidopropylbetaine). The betaine thereby eliminates the negative effect of the oxyalkylene compounds on the air pore content (the foam-preventing effect) and thus significantly improves the efficiency of the air-entraining agents. In addition, the additive composition may comprise 5 to 40% by weight, preferably 10 to 35% by weight, more preferably 15 to 30% by weight of a dispersion powder. The dispersion powder is usually a polymer mixture of vinyl acetate and further constituents, such as polypropylene glycol or cellulose ethers. Polypropylene glycol may be a component of the dispersion powder or a polymer dispersion prepared with the dispersion powder. Preferably, the polypropylene glycol has a molecular weight between 500 and 5000 and is present in an amount of 2 to 8 wt .-% based on the dispersion powder. With respect to the amount of cement, the polymer varies in the range between 5 and 10% by weight. Also, wet cellulose ether may be used as a component in the dispersion powder. In this case, moist cellulose ether (40-70% H ₂ O) is mixed with an aqueous or organic additive suspension or solution at 20 to 60 ⁰ C and the resulting mixture then dried at 80-160 ⁰ C and ground. As additives, polymer dispersions, polyacrylamides and polyurethanes are used. The performance properties of the cellulose ether additive mixtures thus produced differ from simple dry mixtures of the pulverulent individual components. The thickening effect is delayed and the rheological properties differ.

The additive composition may further comprise from 5 to 40% by weight, preferably from 10 to 35% by weight, more preferably from 15 to 30% by weight of a hydrophobing agent. The hydrophobing agent is selected from the group consisting of metallic soaps, complex zinc soap, magnesium soap and / or calcium stearate, although other water repellents known in the art may be used.

The basic substances are brought together in a mixing process and prevented from segregation by a carrier material. The entire additive composition can be prepared in powder, dry, dissolved or liquid form. The additive composition according to the invention can be used to prepare a stabilizing, pore-forming and flowable construction material based on mineral binders. The building material is preferably a plaster, a concrete, a mortar or a screed and can be used both in the static and in the non-static area and for building materials with and without reinforcement.

The preparation of the building material on a mineral-bound base is carried out by mixing (A) 10 to 90 wt .-%, preferably 15 to 80 wt .-%, particularly preferably 20 to 60 wt .-% cement, optionally plus lime, fly ash and / or limestone flour, (B) 10 to 90% by weight, preferably 20 to 85% by weight, particularly preferably 40 to 80% by weight of additives, and (C) 0.01 to 0.7% by weight, preferably 0.04 to 0.65 wt .-%, particularly preferably 0.05 to 0.6 wt .-% based on (A), of the inventive additive composition.

The mixing process entraps air, with air entrapment being stable, i. without segregation and without releasing the air when compression again, is achieved. As a result, a sufficient pore content for a desired frost and Taumittelbeständigkeit the building material is achieved. The resulting pore volume of 3 to 30% by volume is also distinguished by a very good distribution of capillary and non-capillary pores. The determination of the pore volume is carried out by means of an air pore pot.

The term "cement" refers to a hydraulic binder for the building materials mortar, plaster and concrete. It is an inorganic, non-metallic, finely ground material that solidifies and hardens after mixing with water as a result of chemical reactions with the water and remains solid and stable even after hardening under water. From a chemical point of view, cement is mainly siliceous calcium with proportions of aluminum and iron, which is a complex mixture of substances. In general, it also contains proportions of sulfates. Another binder (as a partial replacement) may also be lime. Among the cements, for example, CEM I-III and R-ALL of 32.5 to 52.5 are usable in the present invention. The aggregate can be of organic or inorganic (mineral) origin and includes, for example, sand, quartz sand, stones, natural pumice, expanded clay, expanded glass, lava rock, wood chips, wood wool, EPS and / or polystyrene. By EPS, the person skilled in the art understands expandable polystyrene, which are small polystyrene beads which are provided with an expansion agent, for example pentane. When heated, the styrofoam beads expand to form the well-known styrofoam form, ie foamed polystyrene. EPS is therefore a precursor of foamed polystyrene.

An inventive building material is characterized by a flow effect (slump) between 40 and 90 cm. The flow is determined by a method known in the art with a spreading table.

The stabilizing additive composition according to the invention produces a very stable defined air pore content of between 3 and 30% in mineral-bonded fresh concrete, plaster or mortar. In the compound, the aggregates can no longer separate (additives with less

Density usually sets against high-density aggregates). It results in a building material composition according to the invention a homogeneity of 90% or more with respect to the segregation and

Deposition behavior. The determination of the homogeneity can by

Concrete cross-section grain distribution analysis done.

In the same operation, the water / cement value (W / Z value) is kept below 0.50%. This has the consequence that the mineral binder (cement) has the ideal setting conditions. The water / cement value can be up to 0.25% depending on the concrete flow properties and their

Consistency requirements are reduced. At the same time by the water

Shrinkage and shrinkage cracking minimized and accelerated the setting.

The once set air pore contents are kept stable and an increase of the air pore content by the mixing during transport is counteracted. That is, the set in the first mixing process Pore content can not change much (completed chemical reaction). If the content is to be changed nevertheless, this can only be achieved by a very high energy output (long mixing at the highest level). In general, changes in the composition of the invention by a long transport (in the truck mixer), the pore volume by max. 5%.

Another important point is that the additive composition according to the invention for mineral-bonded building materials is absolutely neutral in impact. This means that all additives listed in the Building Regulations List can be used to produce concretes, mortars and plasters.

The advantages of the building material according to the invention can be summarized as follows:

Very high homogeneity: (no settling behavior of the

Surcharges, no segregation)

Very good insulation properties: (the λ-value is about 50% better than normal concrete (improvement from 2.1 in normal concrete to about 1, 0 in a concrete according to the invention)

Room conditioning effect: (brick properties) Light and good workmanship: (low post-treatment) Corrosion protection improvement: (by a denser cement stone) Binder partial replacement: proportionate, by limescale, such as. at Kalksandstein fly ash

Very high elasticity: improved modulus of elasticity

Use of PP-Fasem Low bulk density: (up to 20% weight saving compared to

Normal concrete without use of

Lightweight aggregates)

Compressive Strength: Ranges from LC 2/4 to LC 30/33

(Milled lightweight concrete without

Light aggregate or with mineral Lightweight aggregates, or from C 8/10 up to C 40/45)

Shrinkage minimization: Polypropylene glycol is added as shrinkage reducing component (1 - 10%)

The invention further relates to components made from the building material according to the invention, such as wall elements in sandwich, Hohlwand- and monolithic design, and stone formats. The components are cast horizontally or while standing.

A multilayer wall structure of the prior art sets connecting elements (a reinforcement) between the individual layers, e.g. between a high-density supporting component and a low-density insulating layer. In the case of the components according to the invention, reinforcement can be dispensed with because of the uniformly distributed pore volume. This means a considerable manufacturing advantage.

The building material can be produced as ready-mixed concrete, in-situ concrete or as bagged goods. The concretes can be produced with a whisk, a free-fall mixer, a compulsory mixer, a drum mixer, a swirl mixer or a plate mixer.

Different types of aggregates can be combined with each other in the concrete types without the risk of segregation (extreme case: gravel 2 - 8 mm in combination with EPS foam balls).

Another positive feature is that although water vapor can diffuse through the concrete, mortar or plaster, however, no salts, e.g. Chloride, carbonates, sulfates, immigrate and there cause damage (efflorescence, corrosion, mold, microbial formation).

The water penetration depth of a concrete according to the invention is reduced from the prior art of 1, 5 cm up to 0.7 cm. The means, by the additive composition according to the invention can be produced according to DIN WU (impermeable to water) concrete.

The desired values for mineral-bound building materials can be achieved for the first time by means of a mechanical mixing energy / time, without the need for many additives.

Likewise, there can be no deposition behavior of aggregates more (eg concrete mix of EPS foam beads and gravel aggregate, where so far the heavy aggregate has settled on the ground and the lightweight aggregate swims up). Likewise, there is no settling behavior by the introduction of compaction energy by Rüttelf flaps, vibrating tables or vibrating tables. The pore structure acts as an internal grid, which keeps the aggregates through the mixing process in their assigned place and no longer releases them.

Bleeding (water settling on the surface of the concrete) was also excluded. This can not be done because of the defined pore volume. The additive composition according to the invention can additionally be used for all consistency groups described in DIN.

The invention will now be further illustrated by way of non-limiting examples with reference to FIGS. 1 to 4.

In total, 42.78 g of the additive composition are added to the mixture. For one cubic meter of concrete (mass 1870 kg), this means that with 1070 kg of sand, 350 kg of gravel, 75 kg of lime-sandstone flour and 375 kg of cement, 0.8 kg of the additive composition is added.
