ACABADO SUPERFICIAL PARA PAVIMENTOS HORMIGONADOS Y PROCEDIMIENTO DE APLICACIÓNSUPERFICIAL FINISH FOR CONCRETE PAVEMENTS AND APPLICATION PROCEDURE
DESCRIPCIÓNDESCRIPTION
CAMPO TÉCNICO DE LA INVENCIÓNTECHNICAL FIELD OF THE INVENTION
La presente invención se engloba en el campo de la industria de los materiales de construcción.The present invention is encompassed in the field of the construction materials industry.
Específicamente, la invención se relaciona con un producto de acabado o fratasado para pavimentos hormigonados, básicamente, comprendido por una mezcla de áridos siderúrgicos y cemento en una proporción de 2/1; el cual, proporciona al pavimento de hormigón una superficie uniforme, resistente, lisa y duradera.Specifically, the invention relates to a finishing or troweling product for concreted floors, basically comprised of a mixture of steel aggregates and cement in a ratio of 2/1; which provides the concrete pavement with a uniform, resistant, smooth and durable surface.
Es también objeto de la presente invención, el procedimiento de aplicación de dicho acabado superficial sobre una porción de pavimento hormigonado.It is also an object of the present invention, the method of applying said surface finish on a portion of concrete pavement.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
La composición habitual del acabado o fratasado superficial aplicado a los pavimentos hormigonados consiste en una mezcla de cuarzo y cemento, en ocasiones, corindón.The usual composition of the finish or surface trowel applied to the concreted pavements consists of a mixture of quartz and cement, sometimes corundum.
Luego que el hormigón vertido en una porción de pavimento ha sido compactado, vibrado y alisado, y éste empieza a perder agua por exudación superficial, la mezcla de cuarzo y cemento es polvoreada uniformemente sobre el mismo, y se espera a que el hormigón endurezca en tal grado que sea apto para pasar los medios mecánicos que llevan a cabo el fratasado correspondiente de dicha porción de pavimento hormigonado.After the concrete poured into a portion of the pavement has been compacted, vibrated and smoothed, and it begins to lose water by surface exudation, the mixture of quartz and cement is uniformly sprayed on it, and the concrete is expected to harden. such a degree that it is apt to pass the mechanical means that carry out the corresponding troweling of said portion of concreted pavement.
Estas soluciones conocidas tienen la desventaja de que requieren la explotación de recursos naturales, en este caso, cuarzo. Es conocido que la industria de materiales de construcción demanda, cada vez más, gran cantidad de material que proviene de los recursos naturales, cuya sobreexplotación puede conllevar el agotamiento de dichos recursos naturales que requirieron el paso de siglos para formarse, atentando contra la exigencia social de protección medioambiental y desarrollo sostenible.These known solutions have the disadvantage that they require the exploitation of natural resources, in this case, quartz. It is well known that the construction materials industry demands, increasingly, a large amount of material that comes from natural resources, whose overexploitation can lead to the depletion of said natural resources that required the passage of centuries to be formed, attacking the social requirement of environmental protection and sustainable development.
Por otro lado, las industrias generan gran cantidad de residuos que contienen una elevada cantidad de elementos reciclables. Por ejemplo, los residuos siderúrgicos, es decir, los residuos de escoria negra de horno eléctrico de arco (EHEA) generados de la fase de fusión de la chatarra en las acerías. Solo en las acerías españolas se generan casi dos millones de toneladas al año de escoria negra de horno eléctrico de arco (EHEA).On the other hand, industries generate large amounts of waste containing a high amount of recyclable elements. For example, iron and steel waste, that is, waste from black slag from the electric arc furnace (EHEA) generated from the melting phase of scrap in steel mills. Only in the Spanish steelworks are generated almost two million tons per year of black slag electric arc furnace (EHEA).
La escoria negra de horno eléctrico de arco (EHEA) representa un residuo impactante para el medio natural. Su reutilización como sustitución de materiales provenientes de recursos naturales sería una manera de controlar la contaminación ambiental y la sobreexplotación de recursos.The black slag of electric arc furnace (EHEA) represents a striking residue for the natural environment. Its reuse as a substitution of materials from natural resources would be a way to control environmental pollution and overexploitation of resources.
Actualmente, la escoria negra de horno eléctrico de arco (EHEA) es reutilizada en la fabricación de hormigones convencionales, morteros, mezclas bituminosas, en las capas base y sub-base de carreteras, en vías férreas, etc. Sin embargo, no es suficiente. Los acopios de escoria negra de horno eléctrico de arco (EHEA) siguen existiendo, lo que nos impulsa a buscar nuevas alternativas a la reutilización de dichos residuos que ayude a reducirlos.Currently, the black slag electric arc furnace (EHEA) is reused in the manufacture of conventional concretes, mortars, bituminous mixtures, in the base layers and sub-base of roads, on railroads, etc. However, it is not enough. The black slag collections of electric arc furnace (EHEA) continue to exist, which drives us to look for new alternatives to the reuse of such waste to help reduce them.
Por tal razón, se requiere diseñar un acabado o fratasado superficial para pavimentos hormigonados que, de forma sencilla y económica, permita superar las desventajas anteriormente expuestas.For this reason, it is necessary to design a surface finish or surface trowel for concreted pavements that, in a simple and economical way, allows to overcome the disadvantages previously exposed.

a) espolvorear uniformemente la mezcla de áridos siderúrgicos de escoria negra de horno eléctrico de arco (EHEA) y cemento en una cuantía de entre 3 y 4 kg/m2 sobre una porción de pavimento hormigonado, compactado, vibrado y alisado que empieza a perder agua por exudación superficial,a) sprinkle uniformly the mixture of black iron slag aggregates of electric arc furnace (EHEA) and cement in an amount of between 3 and 4 kg / m2 on a portion of concreted, compacted, vibrated and smoothed pavement that begins to lose water by superficial exudation,
b) esperar a que el hormigón endurezca en tal grado que esté apto para realizar el fratasado mecánico de la superficie, yb) wait for the concrete to harden to such a degree that it is apt to perform the mechanical troweling of the surface, and
c) realizar el fratasado mecánico de la superficie.c) perform the mechanical troweling of the surface.
Con el presente acabado, se evita la aparición de desconchados, grietas y manchas que normalmente ocurren en el hormigón con el paso del tiempo, así como, se mejora su resistencia al impacto y al desgaste por abrasión respecto a los acabados conocidos a base de cuarzo y cemento.With the present finish, the appearance of chipping, cracks and stains that normally occur in the concrete over time is avoided, as well as, its resistance to impact and abrasion wear is improved with respect to the known finishes based on quartz and cement.
Así mismo, si bien las propiedades y prestaciones del acabado superficial obtenido son similares o equivalentes a las de un fratasado realizado con cuarzo y cemento, adicionalmente se aportan las siguientes ventajas:Likewise, although the properties and benefits of the surface finish obtained are similar or equivalent to those of a trowel made with quartz and cement, additionally the following advantages are provided:
- se sustituyen materiales provenientes de recursos naturales por materiales reciclados, con lo cual, se mitiga la sobreexplotación de las canteras de dichos recursos naturales, y a su vez, se reducen los acopios de escoria siderúrgica dañinos para el medio ambiente.- materials from natural resources are replaced by recycled materials, thereby mitigating the overexploitation of the quarries of these natural resources, and at the same time reducing the accumulations of iron scum harmful to the environment.
- se disminuye el total de energía empleada en la fabricación del acabado superficial, pues se elimina la necesidad de invertir energía en procesos de extracción de los áridos.- The total energy used in the manufacture of the surface finish is reduced, since the need to invest energy in the extraction processes of aggregates is eliminated.
- igualmente, se contribuye a reducir la emisión de gases contaminantes, comúnmente generados durante la extracción de los áridos. - Likewise, it contributes to reduce the emission of polluting gases, commonly generated during the extraction of aggregates.
