También afecta al sector cerámico ya que se basa en la reutilización de sus lodos cerámicos.The invention falls within the technical sector of construction more specifically in relation to cements and asphalt mixes. It also affects the ceramic sector since based on the reuse of its ceramic sludge.
En la instrucción técnica del hormigón estructural y en su capítulo 29 apartado 2° referente a las adiciones, indica qué son materiales inorgánicos, puzolánicos o con hidraulicidad latente que finamente divididos pueden ser añadidos al hormigón para mejorar algunas de sus características técnicas.In concrete technical instruction structural and in its chapter 29 section 2 regarding the additions, indicates which are inorganic, pozzolanic or with latent hydraulics that finely divided can be added to the concrete to improve some of its technical characteristics.
Los esmaltes cerámicos en calidad de lodos cerámicos, debidamente tratados, gozan de estas propiedades. También cabe la posibilidad de añadir cierta cantidad de este producto puzolánico a todo tipo de mezclas asfálticas.Ceramic glazes as sludge Ceramic tiles, duly treated, enjoy these properties. It is also possible to add a certain amount of this pozzolanic product to all types of asphalt mixtures.
Así pues el objeto de esta invención es por una parte reciclar un sobrante de la industria cerámica y por otra obtener un producto para el sector de la construcción, de igual o mejores propiedades que el estándar, con el consecuente ahorro económico y medioambiental debido al uso de este sobrante.Thus, the object of this invention is for one part recycle a surplus from the ceramic industry and on the other obtain a product for the construction sector, of equal or better properties than the standard, with the consequent savings economic and environmental due to the use of this surplus.
De aquí la protección en esta patente "Procedimiento de tratamiento para reciclado de esmaltes cerámicos en calidad de lodos cerámicos, para su utilización como puzolanas artificiales y su reutilización para toda clase de cementos y mezclas asfálticas".Hence the protection in this patent "Treatment procedure for recycling enamels ceramics as ceramic slurries, for use as artificial pozzolans and their reuse for all kinds of cements and asphalt mixtures ".
En el sector cerámico español se generan grandes cantidades de residuos y sobrantes, pero el que cuantitativamente ocupa el primer lugar son los esmaltes cerámicos en calidad de lodos cerámicos, de los que aún hoy no se dispone de un método capaz para la reutilización total de los mismos.In the Spanish ceramic sector, large amounts of waste and surplus, but the one that quantitatively ranks first are ceramic glazes in quality of ceramic muds, of which even today there is no method capable of for their total reuse.
Si bien existen algunos procesos en cerámica para absorber una porción de estos residuos y sobrantes, aún queda por reutilizar una parte importante de los mismos. Sectores posibles de reutilización son los cementos y mezclas asfálticas.Although there are some processes in ceramic to absorb a portion of these residues and surpluses, there is still for reusing an important part of them. Sectors Possible reuse are cements and asphalt mixtures.
Se puede demostrar que los lodos procedentes del proceso cerámico están formados principalmente por restos de esmaltes. Estos lodos presentan una composición química y mineralógica similar a la de un esmalte cerámico, una parte de fase vítrea y otra compuesta por minerales como cuarzo, circón, feldespatos, carbonatos, alúmina y mineral arcilloso (caolines) como fases cristalinas, además de una pequeña proporción de colorantes cerámicos.It can be shown that the sludge from the ceramic process are formed mainly by remains of enamels. These sludge have a chemical composition and mineralogical similar to that of a ceramic glaze, a phase part vitreous and other composed of minerals such as quartz, zircon, feldspars, carbonates, alumina and clay mineral (kaolins) as crystalline phases, in addition to a small proportion of ceramic colorants.
Los esmaltes cerámicos en calidad de lodos cerámicos en la forma que se generan, tienen poca actividad puzolánica, con lo cual han de sufrir un tratamiento para que ésta aparezca. Dicho tratamiento comprende los siguientes pasos:Ceramic glazes as sludge ceramics in the form they are generated, have little activity pozzolanic, with which they have to undergo a treatment so that this appear. Said treatment comprises the following steps:
- \bullet\ bullet
- Recolección del sobrante cerámico generado en la limpieza de molinos, depósitos y conducciones. También en los puntos de aplicación de esmaltes cerámicos en las líneas de esmaltado.

La reutilización de esmaltes cerámicos en calidad de lodos cerámicos, tiene como ventaja principal valorizar unos sobrantes, transformando uno en un producto con actividad puzolánica (sólido), y el otro en un agua (líquido) para su reutilización en barbotinas cerámicas.The reuse of ceramic glazes in ceramic mud quality, its main advantage is to value some leftovers, transforming one into a product with activity pozzolanic (solid), and the other in a water (liquid) for its reuse in ceramic slips.
El producto puzolánico obtenido tiene utilidad para su uso junto con cementos, agua y áridos así como con mezclas asfálticas. Por una parte se consigue un ahorro energético muy relevante, al sustituir parte del cemento y mezcla asfáltica por el producto puzolánico. Por otra parte, consigue que los productos finales obtenidos tengan una calidad superior.The pozzolanic product obtained has utility for use together with cements, water and aggregates as well as with mixtures asphalt. On the one hand, very energy savings are achieved relevant, by substituting part of the cement and asphalt mix for the pozzolanic product. On the other hand, get the products obtained endings have a superior quality.
