[EN] Composite steel-concrete beams embedded in the slab (slim-floor) are being increasingly used worldwide in new residential industrial and commercial building projects, as well as in unique infrastructures. However, the current standard design codes applicable in Europe, present several shortcomings. One of the most significant limitations is related to the calculation under fire exposure, where there is a lack of clear design guidance. In addition, many high-performance steels are beginning to be commercialized internationally. The use of these steels, in combination with the use of lightweight concrete with lower thermal conductivity, may significantly increase the fire resistance of this type of beams without the need of using an external protection, hence reducing the carbon footprint at the same time. This thesis suggests the use of a particular section typology (HEB + welded bottom plate) that improves the safety of the current composite beam systems, allowing for different types of steels to be arranged in the section. Plain carbon steels (S275 or S355) can be used for the main profile, while the high-performance steels (HSS or SS) would be employed only on the lower part of the beam. This will allow to balance out the problem of loss of resistance that these beams present when exposed to elevated temperatures, while reducing their cost. To this aim, a first experimental campaign is developed through eight tests, where the distribution of temperatures is analyzed in detail, as the composite beams are being subjected to the action of fire. Subsequently, an innovative solution, originated during the study of the results of this first group of experiments, is produced. This innovation is based on the insertion of an insulating material in the gap generated between the steel profile and the bottom plate (patent P201930438). To prove its novelty, a second and more reduced experimental campaign was developed. It can be concluded that some of the composite beams configured in this thesis are more sustainable, innovative, and provide competitive solutions for residential, industrial or commercial buildings. The use of new materials in embedded steel profiles is proposed in this thesis, as an alternative to the use of classical fire protection solutions (intumescent coatings or sprayed mortars), providing a solution with a better external finish and without the need for maintenance during its service life, which results in the reduction of the associated environmental impact. / [ES] Las vigas mixtas de acero y hormigón embebidas en el forjado, slim-floor, están siendo cada vez más utilizadas a nivel internacional en las nuevas propuestas de edificación tanto residencial, industrial o comercial, así como en infraestructuras singulares. Sin embargo, los códigos de diseño actuales aplicables en Europa, presentan algunas carencias. Una de las más importantes es respecto a su diseño para resistencia al fuego, para el que no existe una guía clara. Por otra parte, algunos aceros especiales, como los aceros inoxidables (SS) o de alta resistencia (HSS), están empezando a comercializarse a nivel internacional. El empleo de estos aceros, en combinación con la utilización de hormigones ligeros de menor difusividad térmica, puede llegar a incrementar significativamente la resistencia frente al fuego de este tipo de vigas sin necesidad de utilizar una protección externa, reduciendo así, a la vez, la huella de carbono. En esta tesis se sugiere la utilización de una tipología particular de sección (HEB + chapa inferior soldada) que mejora la seguridad de los sistemas de viga mixta actuales, permitiendo disponer diferentes tipos de aceros en la sección. Pueden utilizarse aceros normales (S275 o S355) en el perfil principal, mientras que los aceros de altas prestaciones se dispondrían preferentemente en la parte inferior de la sección. Esto permitiría contrarrestar los problemas de pérdida de resistencia frente a altas temperaturas que presentan estas vigas, reduciendo a la vez su coste. Para ello, se desarrolla una campaña de experimentos con ocho ensayos, donde se analiza en detalle la distribución de temperaturas cuando se somete a las vigas mixtas a la acción del fuego. Posteriormente, se presenta una solución innovadora originada durante el estudio de los resultados de los primeros experimentos, que consiste en la interposición de un material de aislamiento térmico en el hueco generado entre el perfil de acero y la chapa inferior (patente P201930438). Para demostrar su novedad, se desarrolla una segunda campaña de ensayos, más reducida. Se puede concluir que las vigas mixtas que se plantean en la presente tesis son soluciones sostenibles, innovadoras y competitivas para edificación residencial, industrial o comercial. El uso de perfiles de acero embebidos propuesto en esta tesis se plantea como una alternativa frente al empleo de soluciones clásicas de protección pasiva (pinturas intumescentes o morteros de proyección), proporcionando una solución con un mejor acabado externo y sin necesidad de mantenimiento durante su vida en servicio, lo cual redunda en la reducción del impacto ambiental asociado. / [CAT] Les bigues mixtes acer-formigó embegudes en el forjat, slim-floor, són cada vegada més utilitzades a nivell internacional en les noves propostes d'edificació tant residencial, industrial, comercial, com d'infraestructures singulars.

En aquesta tesi es proposa la utilització d'una tipologia de secció mixta (HEB + xapa inferior soldada) que millora la seguretat dels sistemes actuals, permetent disposar diferents tipus d'acers en la secció, els acers comuns (S275 o S355) en el perfil principal i els acers especials només en la part inferior.

This thesis deals with the possibility of using secondary raw materials from the energy industry especially the solid residues of high temperature combustion of coal. These materials should be now seen as a material with wide usage especially in the construction industry. One possibility of their usage is a replacement of binding parts in floor systems. The aim is to find the optimal composition of the mixture, which fits all the technical requirements and at the same time reduces the cost of its production. An advanced methods of powder X-ray diffraction analysis, particle size laser diffraction analysis and X-ray fluorescence analysis were used to determine the raw materials. Based on these analysis the experiments were designed focusing on the mechanical properties, the observation of the evolution of hydration’s heat in prepared mixtures and their time of setting and hardening.
