Definitions

  • 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.
  • 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
  • dB decibels
  • 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.
  • concretes 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 ,
  • 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
  • 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.
  • 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.
