Patent Descriptive Report for "ADDITIVE COMPOSITION FOR MINERAL-BASED CONSTRUCTION MATERIAL".

Field of the Invention

The present invention relates to an additive composition as well as

as well as the use of additive composition in mineral-based building materials, the building material additive having a stabilizing, pore-forming effect and also permitting good flowability of the building material. The invention further relates to a process for producing a building material and the material itself. Furthermore, the invention relates to the building material component containing the building material according to the invention.

State of the Art

For millennia, a building material of unparalleled utility and attractiveness has resulted from earth, water, fire and air "elements." Concrete, a solid building material, guarantees a wear-resistant substance. Concrete constructions also have a service life of over 100 years. Solid concrete construction is responsible in the long run for the quality of high value construction. Concrete has one of the 20 minor shape changes among all building materials, for example, static loading, heat or cold influences. Concrete structures are therefore particularly durable.

Concrete and mortar, due to their fine porous and capillary structure, have good thermal insulation. In general, low energy standard requirements 25 can also be met with concrete use, also with respect to the German energy saving decree (EnEV). It should be noted that the energy requirement for heating a home does not depend solely on a transformation value (thermal transmission coefficient in W / m2K) of the wall, but also on a combination of many factors.

Erected concrete constructions have very good soundproofing properties. The sound insulation measurements of solid external concrete walls are at least 45 - 70 decibels (dB) significantly above the insulation of windows and lightweight constructions and special concretes, for example produced with flow stabilizing agents. the requirement for greater acoustic insulation of 55 db is already met with 20 cm thick walls, for example for partition walls in homes.

Concrete also has very good fire barrier properties and belongs to the fire resistance class F 90, where even thin walls allow a concrete construction to stand for at least 1.5 hours. Massive construction increases the chance of saving people without injury four times. Also in case of fire a concrete construction does not release toxic gases. Concrete building materials considerably exceed the current requirements of fire protection technique.

Building materials made of concrete are subdivided into

in classes with high pressure resistance. For site owners and architects this means additional security. Contractions and swellings caused by cold, heat or moisture and consequent cracking of the walls appear to be considerably smaller in the components of concrete construction material. Concrete building material components offer excellent dimensional stability. The statistical advantages of massive construction lately also contribute to other important properties such as wind stability, acoustic protection or moisture protection.

An object of components of building material produced

with concrete contributes to a pleasant room temperature. As an open construction material for diffusion, concretes have the lowest compensating moisture of all wall construction materials. They can absorb moisture and release it only in the next atmospheric change. Wall surfaces remain dry at any time of year and thus offer a pleasant ambient temperature. Concrete walls, moreover, act as a natural air conditioning installation. Temperature fluctuations are compensated by heat absorption or release. In winter the building remains relatively warm, in the correspondingly cool summer. From a medical point of view, concretes offer advantages since they are not toxic, no harmful exhalation occurs and, compared to other building materials, such concretes have minimal radiation exhalation. In addition, concretes have high corrosion and rot resistance, are harmless from a toxicological point of view and are anti-allergic even in direct contact with skin and mouth.

Massive constructions are necessarily imperative constructions.

airable. Thermal energy cannot escape the house through joints or cracks. Massive buildings remain permanently impermeable to the air, as the walls show no or almost no change in the shape of the components of the building material that could later form vanishing points. Massive wallings therefore do not need sealing films, ie beforehand there are no critical areas after long period such as joints and film connections. An air-tight home is not only a guarantee of maintaining long-term thermal insulation protection but also to prevent damage to the building as a result of damp building material components, as "leakage" points lead to formation. of condensed water. Moist walls or ceilings lose their insulating effect and, consequently, are the ideal nutritional substrate for mold fungi.

In a massive construction, mold fungi or other harmful influences are less likely to damage the work. Solid construction and long-term constant quality require only a few maintenance resources.

Concrete building materials are also economically advantageous, on the one hand in relation to the small cost of origin, on the other hand also in relation to small maintenance expenses.

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

• good thermal insulation properties

• obtaining raw material without harmful effect on the environment and energy saving production

· Reduction of emission of harmful substances

• short transport distance in production and supply through the use of local raw materials.

Through the harvesting of raw material exploration pits, nearby recovery fields or valuable biotypes with species-rich flora and fauna emerge. Mineral building materials can be easily reused, for example as aggregate in the production of new mineral building materials, as infrastructure material in road construction, for acoustic walls and the like.

In spite of these advantages, in concrete, precisely these properties still need improvements, that is, they need improvements regarding stability / service life, thermal insulation, acoustic insulation, fire barriers, ambient temperature, static and waterproofing. light.

It is therefore the task of the present invention to master these disadvantages of concrete building materials according to the state of the art regarding stability / service life, thermal insulation, acoustic insulation, fire barriers, ambient temperature, static and light impermeability. without influencing pressure resistance.

Detailed Description of the Invention:

Pore forming agents are used to produce enclosed air micropores in concrete and mortar. The additive composition comprises from 5 to 50% by weight, preferably 10 to 45% by weight, particularly preferably from 15 to 40% by weight of at least one air pore forming agent. The air pore forming agent for the additive composition according to the invention is preferably selected from a group comprising alpha olefin sulfonates, alkyl benzene sulfonates, alkyl sulfate, alkyl naphthalenesulfonate Na salts, naphthalene derivatives and / or sodium lauryl sulfate.

Additive compositions further comprise 5 to 50 wt%, preferably 10 to 45 wt%, particularly preferably 15 to 40 wt% of at least one thickener. The thickener is preferably chosen from methylcellulose (MC), methylhydroxyethylcellulose (MHEC), methylhydroxypropylcellulose (MHPC), hydroxyethylcellulose (HEC) and / or polyacrylamide.

The additive comprises as other components 10 to 60 wt%, preferably 15 to 55 wt%, particularly preferably above 35 and up to 50 wt% of at least one liquefactor. The liquefactor is preferably chosen from a group comprising melamine resin, polycarboxylate and / or lignin sulfate derivatives.

The additive composition further comprises, as other components, 5 to 40 wt%, preferably 10 to 35 wt%, particularly preferred of 15 to 30 wt% of at least one flow agent, the flow agent being It is chosen from a group comprising melamine resin sulfonates, polycarboxylate ether and / or naphthalosulfonates. Naphthalenesulfonates are based on unsaturated mono- and / or dicarboxylic acid derivatives, C10 -C15 oxyalkylene glycolalkenyl ethers and / or oxyalkylene glycol alkenyl esters.

Finally the additive compositions further comprise 5 to 50 wt.%, Preferably 10 to 45 wt.%, Particularly preferred of up to 40 wt.% Of at least one stabilizer, the stabilizer being selected from the group comprising biopolymers, polysaccharides, glycolic acid. co and / or bentonite.

The aforementioned components, therefore air pore forming agents, thickeners, liquefactors, flow agents and stabilizers may be employed in powdered, dry or liquid (diluted) form. Preferred carrier material for the liquid form is water.

Additionally, the additive composition may still be diluted.

with an inert (powder) or H2O support material.

Additive composition is characterized by acting in a stabilizing and pore-forming manner on a building material composition. Contrary to the state of the art, the additive composition does not influence pore formation by gas development (ie pore formation by the mined mineral. Pore formation is better clarified in the paragraph on the production of a construction material.

Other advantages of the additive composition according to the invention are a reduction in water / cement value (fluidization), improvement of the flow effect, reduction of the shrinkage measure, better sealing and better dispersion.

The additive composition, as another component, may comprise 5

up to 40 wt%, preferably 10 to 35 wt%, particularly preferred 15 to 30 wt% of an activator. The activator is usually calcium sulfoaluminate, calcium chloride, arene and alkylsulfonic acids as well as their salts, preferably alkaline salts. Other accelerators known from the prior art may also be used.

The additive composition may further comprise as other components 5 to 40 wt%, preferably 10 to 35 wt%, particularly preferably 15 to 30 wt% of a shrinkage reducing agent to minimize the emergence of cracks due to contraction. The shrinkage reducing agent is preferably chosen from combinations of glycol and / or cycloaliphatic mixtures and / or a synergistic mixture of an alkylether oxyalkylene adduct and short chain oxyalkylene glycols. In addition, as additives to minimize shrinkage in cement bonded building materials, alkanedioles with OH end groups can be further added. Addition amounts are between 0.2 and 10% by weight relative to cement. Particularly suitable is also 2,2-dimethylpropane-1,3-diol. Sulfonic acid, phosphoric acid and phthalic acid esters can also be used as a shrinkage reducing agent. Further preferred are: trioctylphosphate, tri-cresylphosphate, triphenylphosphate, diisoctylphthalate and phenylalkylsulfonates (1-10 carbon atom alkyl radicals). Also preferred is a mixture of dipropylene glycol tert-butyl ether, dipropylene glycol and a small amount of betaine (cocoamidopropyl betaine). Betaine compensates for the negative effect of oxyalkylene compounds on air pore content (the defoamer effect) and thus significantly improves the effectiveness of the air pore forming agent.

Additionally, the additive composition may comprise 5 to 40%.

by weight, preferably 10 to 35% by weight, particularly preferably 15 to 30% by weight of a dispersing powder. Most often the dispersion powder is a polymer blend of vinyl acetate and other components such as polypropylene glycol or cellulose ether. Polypropylene glycol may be a component of the dispersing powder or a polymer dispersion prepared with the dispersing powder. The polypropylene glycol preferably has a molar mass between 500 and 5000 and is present in an amount of 2 to 8% by weight relative to the dispersing powder. The polymer varies with respect to the amount of cement in the range of 5 to 10% by weight. Similarly, wet cellulose ether may be employed as a component in the dispersing powder. For this, wet cellulose ether (40-70% H2O) is mixed at 20 to 60 ° C with an aqueous or organic suspension or additive solution and the mixture obtained is then dried at 80 - 160 ° C, and ground. . As additives, polymer dispersions, polyacrylamides and polyurethanes are employed. The properties of the technical applicability of the cellulose ether additive mixtures thus prepared differ from the simple dry mixtures of the dry components and the individual powder components. The thickening effect starts in a delayed manner and the rheological properties are different.

The additive composition may further contain 5 to 40% by weight of

preferably 10 to 35% by weight, particularly preferred 15 to 30% by weight of a waterproofing agent. The waterproofing agent is selected from the group comprising metal soaps, complex zinc soap, magnesium soap and / or calcium stearate, and other waterproofing agents known in the prior art may also be employed.

The base substances are brought together in one mixing step and the separation of the mixture is prevented by a support material. The total additive composition may be produced in powder, dried, diluted or liquid form.

The additive composition of the present invention may be used for the production of a stabilizing, pore-forming and flowable, mineral-bound base building material. Preferably the building material is a plaster, a concrete, a mortar or a floor and may be employed in the statistical or non-statistical field as well as for framed or frameless building materials.

The production of the mineral based bonded building material is made by mixing (A) 10 to 90 wt%, preferably 15 to 10 80 wt%, particularly preferred 20 to 60 wt% cement, optionally with more limestone, fly ash and / or limestone flour, (B) 10 to 90 wt%, preferably 20 to 85 wt%, particularly preferred 40 to 80% aggregates, and (C) 0.01 to 0.7 wt%, preferably 0.04 to 0.65 wt%, particularly preferably 0.05 to 15 0.6 wt% with respect to (A) of the additive composition of the present invention. dog.

Through the mixing process, air inclusion is achieved, and air inclusion is stable, ie without mass separation and without releasing air at the time of compression. This results in a sufficient pore content for a desired freeze and thaw resistance of the building material. The pore volume obtained from 3 to 30% by volume is characterized by a very good distribution of capillary and non-capillary pores. The pore volume is determined by means of an air pore container.

Under cement the technician understands a hydraulic binder for the

mortar, plaster and concrete of building materials. It is an inorganic, non-metallic, finely ground material which, after mixing with water by chemical reaction with water, self-solidifies and hardens and after hardening, even under water, remains solid and maintains a constant volume. . From a chemical point of view, cement is mainly calcium acidulated with silicic acid with aluminum and iron fractions, which is a complicated mixture of materials. In general, it also contains sulfate fractions. Another binder (as a partial substitute) may also be limestone. Among the cements, they may be employed according to the invention for example EMC I-Ill and R-ALL from 32.5 to 52.5.

The additive may be of organic or inorganic origin 5 (mineral) and covers, for example, sand, quartz sand, stones, pumice, expanded clay, expanded glass, lava gravel, wood shavings, wood wool, EPS and / or styrofoam. Under EPS, the person understands expandable polystyrene, which are small styrofoam beads provided with a blowing agent, for example pentane. When heated, the small styrofoam spheres 10 swell, resulting in the known styrofoam, i.e. foamed polystyrene. EPS is therefore the pre-step of foamed polystyrene.

A building material according to the invention is characterized by a flow effect (spreading measurement) of between 40 and 90 cm. The yield effect is evaluated according to methods known in the prior art by means of a spreading measuring table.

The stabilizing additive composition according to the invention in fresh concrete bonded with mineral, plaster or mortar produces a very stable defined pore content of between 3 and 30%. In the compound, the additives can no longer be separated from the mixture (very low density additives generally settle in the presence of high density additives). A building material composition according to the invention results in a homogeneity of 90% or more with respect to separation and settling behavior. The homogeneity can be determined by grain distribution analysis in concrete, in cross section.

The water / cement value (W / Z value), in the same work stage, is kept below 0.50%. As a consequence, the mineral binder (cement) has a prediction of ideal cementations. The water / cement value 30 can be reduced to an amount of 0.25%, depending on the concrete's flow properties and the need for its consistency. At the same time, both shrinkage and cracking are greatly minimized by water and grip behavior is accelerated.

Adjusted air pore contents are kept stable and an increase in air pore content is counteracted by mixing during transport. That is, the pore content adjusted in the first mixing step no longer changes significantly (closed chemical reaction). If the content still needs alteration, this can only be done with very high energy supply (slow mixing at the highest stage). Generally the pore volume in the composition according to the invention, during long transport (in the mobile mixer) changes by a maximum of 5%.

Another important point is that the additive composition according to the invention is absolutely neutral for mineral based building material. That is, all additives listed in the building regimental list can be used for the production of concretes and mortars as well as renders.

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

Very high homogeneity: (no settling behavior

additives, no separation)

Insulation properties very good- (λ-value is ca. 50% better than: in normal concrete (improvement

2.1 in normal concrete for ca. 1.0 in concrete according to the invention)

Room climate effect: (brick properties)

Good and easy processability: (slight aftertreatment)

Improved protection against (through cement stone plus corrosion: dense)

Partial binder substitute: Proportional, by limestone as by

example gray limestone sand wheel

Very high elasticity: E-Module enhanced by the use of

bras-PP

Low crude density: (up to 20% weight savings over

normal concrete (without light additives)

Pressure resistance: Runs from LC 2/4 to LC 30/33 (concrete

structural density without light additive or with lightweight building additives, or from C 8/10 to C 40/45) Minimization of cracks due to polypropylene glycol is added by turbulence as a reducing component of

cracks due to contraction (1-10%)

The invention further relates to building elements manufactured from the building material according to the invention, such as elements for building walls in building modes such as sandwich, hollow walls, and monolithic as well as in stone shapes. The building elements are cast in a flat or standing form.

A multi-layer wall construction according to the prior art places connecting elements (a frame) between the individual layers, for example between a high density support component and a lower density insulating layer. In the building elements according to the invention, a frame is dispensable by virtue of the uniform distribution of the pore volume. This represents a huge technical advantage in manufacturing.

Construction material can be fabricated as conveying concrete, on-site concrete or bagged material. The designs can be produced in a mixer, free fall mixer, forced drive mixer, rotary mixer, cyclone mixer or disc mixer.

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

Another positive feature is that water vapor can diffuse into concrete, mortar or plaster, but no salt - for example chlorides, carbonates, sulphates - can migrate to concrete and cause damage (skimming, corroding, molding, development). microbes).

The water penetration depth of a concrete produced by

The invention according to the invention has hitherto been reduced according to the prior art from 1.5 cm to up to 0.7 cm. That is, by the additive composition according to the invention, a waterproof concrete as prescribed by DIN can be produced.

Desired values for mineral bonded building materials can be obtained initially with energy / mechanical mixing time, without the need for many additives.

Similarly there can no longer be any additive settling behavior (eg concrete mixing of EPS foam balls and gravel addition where so far the heavy additive has deposited at the bottom and the light additive has supernatant). Similarly, sedimentation behavior is no longer due to the introduction of densification energy by vibration bottles, vibration tables or stirring tables. The porous structure fuses like an internal lattice grid which in the mixing stage holds the additives in the places assigned to them and no longer loosens them.

Exudation (sedimentation of water on the concrete surface) has also been eliminated. This can no longer occur due to the defined pore volume. The additive composition according to the invention may also be used for all consistent groups described in DIN.

The invention should now be illustrated by way of non-limiting examples with reference to Figures 1 to 4.
