DESCRIPCIÓNDESCRIPTION

COMPOSICIÓN PARA UN HORMIGÓN LIGERO MIXTO COMPOSITION FOR A MIXED LIGHTWEIGHT CONCRETE

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a una composición para un hormigón ligero mixto adecuado para construcciones para animales silvestres y domésticos, aunque puede tener cualquier otro uso.The present invention relates to a composition for a lightweight mixed concrete suitable for constructions for wild and domestic animals, although it may have any other use.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En la actualidad se conocen muchos tipos de hormigones para usos diversos, si bien por parte del solicitante no se conoce ningún hormigón específico para construcciones de refugios o estructuras para animales, inconveniente que se soluciona con el hormigón de la composición de la invención.Currently, many types of concrete are known for various uses, although the applicant does not know of any specific concrete for the construction of shelters or structures for animals, a problem that is solved with the concrete of the composition of the invention.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

La composición para un hormigón de la invención comprende, en proporciones en peso variables:The composition for a concrete of the invention comprises, in variable proportions by weight:

-Cemento,-Cement,

-Cal,-Lime,

-un primer árido fino de granulometría inferior a 4mm, que contribuye a la estabilidad de volumen, resistencia y economía del hormigón,-a first fine aggregate with a grain size of less than 4mm, which contributes to the volume stability, resistance and economy of the concrete,

-un segundo árido fino de granulometría inferior a 4mm, que contribuye a la estabilidad de volumen, resistencia y economía del hormigón,-a second fine aggregate with a grain size of less than 4mm, which contributes to the volume stability, resistance and economy of the concrete,

-Årido grueso de granulometría comprendida entre 4mm y 8mm, que contribuye a la estabilidad de volumen, resistencia y economía del hormigón,-Coarse aggregate with a grain size between 4mm and 8mm, which contributes to the volume stability, resistance and economy of the concrete,

-Årido arcilla expandida, y-Arid expanded clay, and

-Agua.-Water.

De esta forma se consigue un hormigón ligero que es mixto, por tener en su composición como conglomerante cal y cemento, y que además, presenta las siguientes ventajas:In this way, a lightweight concrete is achieved that is mixed, as it has lime and cement in its composition as a binder, and that also has the following advantages:

-Gran ligereza y reducción de peso, si se compara con el hormigón convencional, pues presenta densidades inferiores a 2.000 kg/m3. Esto permite realizar construcciones más económicas,-Great lightness and weight reduction, when compared to conventional concrete, since it has densities less than 2,000 kg/m3. This allows for more economical constructions,

-Gran resistencia, estabilidad y durabilidad, al tratarse de un hormigón ligero resistente (al presentar una resistencia a la compresión superior a 10 MPa si se compara con hormigones ligeros para aislamiento). Además, es dimensionalmente estable, indeformable y mantiene sus propiedades inalteradas con el paso del tiempo si se compara con otros materiales como el plástico.-Great resistance, stability and durability, as it is a resistant lightweight concrete (having a compression resistance greater than 10 MPa when compared to lightweight concretes for insulation). In addition, it is dimensionally stable, non-deformable and maintains its properties unchanged over time when compared to other materials such as plastic.

-Buenas propiedades de aislamiento, ya que el incremento del aislamiento térmico, si se compara con un hormigón convencional, es del orden del 5%. La disminución de densidad permite una disminución de la conductividad térmica y por tanto un incremento del aislamiento térmico.-Good insulation properties, since the increase in thermal insulation, when compared to conventional concrete, is of the order of 5%. The decrease in density allows a decrease in thermal conductivity and therefore an increase in thermal insulation.

-Es incombustible, al tratarse de un hormigón 100% mineral, y es seguro incluso en caso de incendio si se compara con un hormigón ligero fabricado con árido ligero de origen orgánico.-It is non-combustible, as it is 100% mineral concrete, and is safe even in the event of fire when compared to lightweight concrete made with lightweight aggregate of organic origin.

La presencia de cal en la composición de este hormigón ligero ayuda al cuidado del medioambiente a través de la reducción del CO2 si se compara con un hormigón ligero fabricado solamente con cemento.The presence of lime in the composition of this lightweight concrete helps care for the environment through the reduction of CO 2 when compared to a lightweight concrete made only with cement.

-La presencia de cal en la composición de este hormigón ligero permite que sea más transpirable, antibacteriano si se compara con un hormigón ligero fabricado solamente con cemento, lo que le hace especialmente adecuado para construcciones para animales.-The presence of lime in the composition of this lightweight concrete allows it to be more breathable and antibacterial compared to a lightweight concrete made only with cement, which makes it especially suitable for constructions for animals.

-La presencia de cal en la composición de este hormigón ligero permite presentar menos fisuración y retracción si se compara con un hormigón ligero fabricado solamente con cemento.-The presence of lime in the composition of this lightweight concrete allows for less cracking and shrinkage when compared to a lightweight concrete made only with cement.
