Procedimiento de reciclado de residuos procedentes de lodos cerámicos como adiciones para cementos de alta resistencia.Waste Recycling Procedure from ceramic sludge as additions for high cements resistance.
El objeto al cual se refiere la invención que se protege en esta Patente, consiste en un "Procedimiento de reciclado de residuos procedentes de lodos cerámicos como adiciones para cementos de alta resistencia".The object to which the invention relates to protects in this Patent, consists of a "Procedure of recycling of waste from ceramic sludge as additions for high strength cements. "
El sector industrial de la construcción demanda nuevos productos que ofrezcan mejores prestaciones que los obtenidos con materiales y tecnologías convencionales, contando entre sus requerimientos el que no sean perjudiciales para el medio ambiente y permitan ahorro energético.The industrial construction sector demands new products that offer better performance than obtained with conventional materials and technologies, counting among its requirements that are not harmful to the environment environment and allow energy savings.
Esta demanda, junto al problema que presenta el volumen creciente de residuos industriales, pone de manifiesto la necesidad de buscar alternativas para su reutilización, siendo posible para algunos de ellos, su incorporación en la formulación de nuevos materiales.This demand, together with the problem presented by the increasing volume of industrial waste, highlights the need to look for alternatives for reuse, being possible for some of them, its incorporation into the formulation of new materials.
Por otra parte, la industria del cemento demanda productos de bajo coste que se puedan adicionar de forma que le confieran propiedades mecánicas complementarias, tales como actividad puzolánica o resistencia a la abrasión. Para ello se requiere que disponga de una granulometria adecuada, de forma que simplifique los requerimientos técnicos de la adición.On the other hand, the cement industry demands low cost products that can be added so that you confer complementary mechanical properties, such as pozzolanic activity or abrasion resistance. To do this requires that you have adequate granulometry, so that simplify the technical requirements of the addition.
En la actualidad, las empresas cerámicas buscan soluciones para reducir sus desechos, ya que la regulación actual sobre vertidos es muy estricta y ha aumentado los costes para la eliminación de sus residuos hasta límites difícilmente soportables.Currently, ceramic companies are looking for solutions to reduce your waste, since the current regulation over spills is very strict and has increased costs for the disposal of your waste to hard limits bearable
En efecto, los lodos se almacenan en vertederos controlados, como residuos húmedos peligrosos por su contenido en metales pesados. Ello obliga a realizar análisis periódicos de dichos vertidos, lo que implica un importante coste añadido a las empresas que los producen.Indeed, sludge is stored in landfills controlled, such as hazardous wet waste due to its content in heavy metals This requires periodic analysis of such discharges, which implies a significant added cost to Companies that produce them.
La finalidad de la invención que constituye el objeto de esta Patente, consiste en la recuperación y reciclado de los lodos producidos en el pulido de baldosas cerámicas de gres, para su empleo como adiciones puzolánicas o por sus propiedades de resistencia a la abrasión en la obtención de nuevos productos para la construcción.The purpose of the invention that constitutes the object of this Patent, consists in the recovery and recycling of sludge produced in the polishing of ceramic stoneware tiles, for use as pozzolanic additions or for their properties of abrasion resistance in obtaining new products for construction
En el proceso de fabricación de gres porcelánico, se produce un residuo húmedo de grano fino, que proviene del pulido de la superficie de baldosas y que tiene la misma composición que el gres, encontrándose además en ella carborundo, que le confiere una mayor resistencia a la abrasión.In the porcelain stoneware manufacturing process, a wet fine grain residue is produced, which comes from polishing of the tile surface and that has the same composition as the stoneware, being also in her carborundo, which confers Greater abrasion resistance.
Las características de las partículas de gres porcelánico (actividad puzolánica y dureza) hacen el material óptimo como sustituto del cemento en hormigón de altas prestaciones y otros productos derivados, y más rentable ambiental, energética y económicamente que el convencional.The characteristics of stoneware particles Porcelain (pozzolanic activity and hardness) make the material optimal as a substitute for high performance concrete cement and other derivative products, and more profitable environmental, energy and economically than conventional.
Así pues, el objetivo de la invención es triple, coherentemente con la triple rentabilidad señalada:Thus, the objective of the invention is threefold, Consistent with the triple profitability indicated:
- a)to)
- - Reciclar (y por tanto, no verter) un residuo de la industria cerámica, en forma de lodo, que entraña problemas de eliminación.- Recycle (and by therefore, do not pour) a waste from the ceramic industry, in the form of mud, which involves elimination problems.
El material residual, con metales tóxicos, es incluido en el cemento como adición, lo que permite no sólo deshacerse de él, sino incluso atribuirle un valor añadido. Por su parte, los metales se fijan en la estructura del cemento fraguado, quedando así inmovilizados.The residual material, with toxic metals, is included in the cement as an addition, which allows not only get rid of it, but even attribute it added value. For his part, the metals are fixed in the structure of the cement set, thus being immobilized.
- b)b)
- - Obtener un cemento de menor coste energético y económico que el convencional, como consecuencia de la sustitución de cemento por lodos en la confección de morteros y hormigones especiales y productos derivados, siendo el ahorro energético y de emisión de CO_{2} de al menos un 30% a causa de que para generar 1 Tm. de cemento Portland se emite una cantidad de 1 Tm. de CO_{2} debida únicamente a procesos químicos sin contar con la emisión propia de la energía necesaria para su desarrollo.- Obtain a cement with lower energy and economic cost than the conventional one, as a consequence of replacing cement with sludge in the manufacture of mortars and special concretes and products derivatives, being the energy saving and CO2 emission of at least 30% because of that to generate 1 Tm. of cement Portland is issued an amount of 1 Tm. of CO 2 due only to chemical processes without having the own emission of The energy needed for its development.
- c)C)
- - Obtener un cemento con mejores prestaciones mecánicas y mayor durabilidad.- Obtain a cement with better mechanical performance and greater durability.
El volumen de árido necesario para la fabricación de hormigón o productos derivados, así como el precio de los áridos con una cierta resistencia a la abrasión, hace que el uso de dichos áridos encarezca el precio del producto de manera considerable.The volume of aggregate necessary for manufacturing of concrete or derived products, as well as the price of aggregates With a certain abrasion resistance, it makes the use of such aggregates increase the price of the product considerably.
En la actualidad, el filtre calcáreo es, prácticamente, el único que puede usarse a precios razonables, en detrimento de la resistencia a la abrasión.At present, the limestone filter is, virtually the only one that can be used at reasonable prices, in detriment to abrasion resistance.
El hecho de que los lodos tengan un tamaño de grano fino supone un ahorro energético muy importante derivado de la posibilidad de uso directo en morteros y hormigones, tanto como sustitutivos del árido fino como del cemento, debido a sus propiedades puzolánicas.The fact that the sludge has a size of Fine grain means a very important energy saving derived from the possibility of direct use in mortars and concrete, as well as substitutes for fine aggregate and cement, due to their pozzolanic properties.
Por otra parte, las propiedades puzolánicas de los lodos cerámicos confieren un aumento en las prestaciones mecánicas, tanto a cortos como a largos tiempo de fraguado, además de disminuir el tamaño de los poros generados en pastas, morteros u hormigones fabricados con dichas adiciones. Esto supone una mayor durabilidad de los elementos fabricados, así como una mayor protección de las armaduras, en el caso de hormigones estructurales.On the other hand, the pozzolanic properties of ceramic sludge confer an increase in performance mechanical, both short and long setting time, in addition to reduce the size of the pores generated in pastes, mortars or concretes made with these additions. This means more durability of manufactured elements, as well as greater armor protection, in the case of concrete structural.
La industria cementera, por su parte, demanda sustancias con actividad puzolánica a coste razonable y el uso de árido fino de alta dureza para cementos de alta resistencia a la abrasión, cuyos precios son prohibitivos.The cement industry, meanwhile, demands substances with pozzolanic activity at reasonable cost and the use of fine aggregate of high hardness for cements with high resistance to abrasion, whose prices are prohibitive.
Se resuelve así con los lodos cerámicos, la
búsqueda de una alternativa a las escasas puzolanas
naturales y a los altos costes de las puzolanas artificiales.It is thus resolved with ceramic sludge, the search for an alternative to the few pozzolanas
natural and the high costs of artificial pozzolans.
Además, el color blanco de los lodos exentos de colorantes permite su uso bien como puzolanas o bien como árido fino de gran resistencia a la abrasión en cementos blancos, para los que hay escasas posibilidades, debido a la exención de color que exigen dichos cementos.In addition, the white color of sludge free of dyes allows its use either as pozzolans or as aggregate fine high abrasion resistance in white cements, for there are few possibilities, due to the exemption of color that these cements demand.
En cuanto antecede han quedado descritas las ventajas técnicas a las que da lugar el reciclado de lodos cerámicos como adiciones puzolánicas para cementos de alta resistencia, que constituye el objeto de esta Patente.As soon as they have been described the technical advantages that result in sludge recycling ceramics as pozzolanic additions for high cements resistance, which is the subject of this patent.
