Características estructurales del hormigón con árido reciclado mixto reforzado con fibras by Francisco Mena Sebastiá( Book )

2 editions published in 2015 in Spanish and held by 2 WorldCat member libraries worldwide

Despite the advance that has led the incorporation of Annex 15 in the Spanish EHE-08, the use of recycled aggregate concrete (RAC) is minimum in structural applications. This regulation limits the percentage of substitution to 20 % of the coarse fraction. Moreover, only the recycled concrete aggregates (RCA) with ceramic particle content less than 5 % and water absorption less than 7 % are accepted. However, recent studies have shown that most of recycled aggregates produced in Spain exceeds these limitations, mainly due to the high content of ceramic material (mixed recycled aggregates), and absorption capacity water. This fact causes that only 15-20 % of construction and demolition waste (CDW) generated in Spain are treated and revalued as a construction material. This mark is below the goal (70 %) fixed in European regulations for year 2020. Currently, the recycled aggregates from CDW are considered as a waste material, only suitable in applications like filling-material in trenches or road subbase. The main objective of the Doctoral Thesis is demonstrate the feasibility of RAC made with a 100 % of mixed recycled aggregates (MRA) in structural applications. To reach this goal, an extensive experimental campaign (in concrete factory, in UPC ¿Luis Agulló¿ Lab and a field test) was carried out. This field test was part of the construction of an underground parking in C/Badajoz (Barcelona). Six diaphragm-walls were cast from as many doses of mixed RAC. In this experience, two properties were added to the concrete, self-compactability and fiber-reinforced. The aim of this decision was prevent the usual casting difficulties in these structural elements. Three months later, the elements were removed and fragmented in order to obtain specimens. Physical, mechanical and durability properties of the concretes were analyzed, and 18 full-scale flexural slab tests were carried out. Additionally, another experience was carried out in ESCOFET 1886, SA plant (Martorell), in order to verify the feasibility of this type of concrete in an industrial process. The results are satisfactory in both applications, opening new promising prospects for this type of concrete
Interacciones microorganismo-hormigón: métodos de evaluación y posibles soluciones by José M Vaquero Martínez( )

2 editions published in 2013 in Spanish and held by 2 WorldCat member libraries worldwide

La interacción microorganismo-hormigón es un proceso que, debido a la naturaleza porosa del hormigón, lo hace susceptible de ser colonizado por los microorganismos presentes en prácticamente todos los hábitats. Esta interacción puede provocar cambios indeseables en el hormigón o hacer que éste sea un foco de contaminación microbiológica, si bien, en algunos casos, la presencia de microorganismos puede ser beneficiosa. La presente tesis doctoral se focaliza en las interacciones negativas y tiene como objetivos principales, en primer lugar, realizar una selección de sustancias químicas y valorar su efectividad frente a microorganismos patógenos para el ser humano y/o su actividad (Escherichia coli, Staphylococcus aureus, Aspergillus niger,) o frente al crecimiento de microorganismos que pueden provocar el biodeterioro del hormigón (Scenedesmus vacoulatus, Stichococcus bacillaris y Thiobacillus thiooxidans). En segundo lugar, desarrollar una metodología global (ensayos en laboratorio y ensayos de campo) que permita evaluar la efectividad de diferentes agentes químicos frente a diferentes factores a lo largo del tiempo. A nivel de laboratorio se realizan tres campañas de ensayos, en las que se evalúan las prestaciones antimicrobianas de 15 formulados diferentes (10 monocomponente y 5 multicomponente) que contienen 10 principios activos distintos. En la 1ª campaña de ensayos se valora la eficacia de los formulados monocomponente, poniéndose de manifiesto que ninguno de ellos alcanza los objetivos requeridos y, por tanto, se descartan debido a las siguientes razones: perjudicar las prestaciones fundamentales del hormigón (desarrollo de resistencias, densidad y consistencia), lixiviación del principio activo y, no alcanzar los niveles de actividad antimicrobiana aceptables. En la 2ª campaña se emplearon formulados multicomponente, obteniendo excelentes resultados con el formulado PL-UV H+M-2B, el cual presentó una efectividad antimicrobiana duradera en el tiempo sin comprometer el resto de prestaciones. Estas fueron confirmadas en condiciones reales de uso en la fase experimental de campo (puerto de Barcelona) retrasando la aparición de algas sobre la superficie de hormigón hasta en 16 semanas. Por último, en la 3ª campaña se evalúa la efectividad del formulado BXT/ I frente el ataque ácido sulfúrico biogénico producido por el metabolismo del Thiobacillus thiooxidans. En primera instancia se realizan los ensayos por impregnación mediante los cuales se demuestra, de forma cualitativa, que el formulado BXT / I inhibe el desarrollo del Thiobacillus thiooxidans. Posteriormente se lleva a cabo un ensayo en el que simula la acción del ácido sulfúrico biogénico siguiendo el método descrito por Vincke (1999), demostrándose que el empleo del formulado BXT/I reduce en más de un 30% la pérdida de masa de hormigón debida al metabolismo del Thiobacillus thiooxidans, considerándose, de esta manera, una solución efectiva contra este proceso de biodegradación. Desde el punto de vista metodológico, esta tesis doctoral propone una nueva metodología de evaluación global de la eficacia de principios activos antimicrobianos, en la que se abarca el estudio de la influencia del principio activo en las propiedades del hormigón, la posible lixiviación del principio activo, la eficacia del efecto antimicrobiano (cultivo microbiológico en placa de Petri) y su durabilidad, tanto a nivel de laboratorio como en ensayos de campo

Considerando el hormigón como uno de los principales materiales de la construcción de una ciudad, al añadir propiedades adicionales a sus funciones estructurales o de revestimiento de calzadas y fachadas, conseguiríamos dotar de nuevas funcionalidades a las ciudades y con ello hacerlas más "inteligentes" Con el fin de dotar al hormigón de propiedades diferentes a su principal función estrictamente estructural, en este estudio se caracteriza el efecto de la adición de fibras de carbono recicladas en la masa del hormigón. Frente a las características dieléctricas del hormigón, la adición de fibra de carbono, le confiere propiedades conductivas, transformando un material estructural como el hormigón en un material multifuncional. Se realizó un barrido inicial de estudios previos, en los que se han descrito posibles aplicaciones y objetivos perseguidos, como se han abordado las síntesis de materiales y los procedimientos de análisis y caracterización propuestos para el conocimiento de sus propiedades. Partiendo de los conocimientos existentes y empleando materia prima de partida fijada bajo unos condicionantes, se fabricaron una serie de testigos, sobre los cuales se han realizado ensayos de trabajabilidad, comportamiento mecánico y sobre todo propiedades eléctricas (conductividad/resistividad) Del análisis de resultados se extraen comportamientos comparables y otros que difieren de los descritos en los estudios previos, fruto principalmente de las diferencias en las materias primas empleadas, y tipología de muestra ensayada. Los resultados obtenidos, validan la posibilidad de obtener hormigones conductores con las premisas empleadas, pero a la vez generan otras problemáticas a estudiar en el desarrollo del material, mejora de sus propiedades e industrialización. De la misma forma, con los datos obtenidos se analizaron aspectos económicos y medioambientales, comparando con materiales o aplicaciones similares, que tampoco descartan la vía iniciada
Evaluación de la reactividad potencial de áridos expansivos usados en presas de hormigón frente al ataque sulfático interno by Gerard Llobet Pérez( Book )

1 edition published in 2019 in Spanish and held by 1 WorldCat member library worldwide

En la construcción de presas es normal emplear hormigón que ha sido fabricado a partir de áridos del entorno, para abaratar costes de construcción. Esto conlleva muchas veces que los áridos no sean los más convenientes y que se presenten fenómenos de deterioro por procesos de expansión interna. El presente TFG estudia la reactividad potencial de diferentes áridos expansivos así como un potencial método de tratamiento de estos áridos

Bioreceptivity optimisation of concrete substratum to stimulate biological colonisation by Sandra Manso Blanco( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

The lack of green areas in cities is caused by the increase in population and the urbanisation process. However, an increasing interest in city greenery was observed since the beginning of twentieth century. Several benefits are associated with green areas from a social, economic and ecologic point of view. Consequently, the solution to increase the urban green spaces lies in their inclusion on structures¿ surfaces. In that sense, a number of different technologies were developed which can be grouped into green walls and green roofs. Unfortunately, existing systems for both green walls and green roofs present several disadvantages in terms of installation and maintenance costs, low level of integration with the structure, extra loads, limitations in their use in rehabilitation projects, and others. The general objective of this dissertation is to provide a first approach to the possibility of using a structure surface as biological substratum. This was treated considering two different research lines. The first research line includes the modification of the chemical and physical properties of the cementitious material, which will be used as substratum. Then, the second issue is the evaluation of materials¿ bioreceptivity under both laboratory and environmental conditions. Regarding the material, chemical properties were firstly studied. pH was taken as a priority from the diversity of involved chemical properties. In that sense, two different ways to obtain a low pH cementitious material were studied. First, it was attempted to reduce the pH of the most common hydraulic binder, Ordinary Portland Cement (OPC). Then, the characterisation of Magnesium Phosphate Cement (MPC) as a hydraulic binder of naturally low pH was carried out. Insufficient reduction in the pH of OPC was obtained and properties such as flexural and compressive strength were highly affected. In contrast, positive results were obtained regarding the use of MPC as hydraulic binder for the specific purpose to be used as a biological substratum. Regarding the physical properties, porosity and roughness were the main properties considered. For that purpose, modifications were made to the composition of different samples, by means of modifying the hydraulic binder, granular skeleton, the water to cement ratio and the amount of cement paste. The methodology used for the estimation of the optimal cement paste content worked well for OPC specimens although MPC responded differently. The characterisation of the twenty-three initial materials¿ bioreceptivities provided significantly different results. Consequently, six different mix designs were selected to be exposed to colonisation. Afterwards, the evaluation of the materials¿ bioreceptivity in terms of colonisation was studied under both laboratory and environmental conditions. Regarding the experimental program under laboratory conditions, an accelerated laboratory test was carried out to evaluate the behavior of different specimens when they were exposed to colonization. Magnesium Phosphate Cement specimens obtained better results than OPC mortars for algal colonisation under those particular conditions. Finally, specimens were also evaluated under environmental conditions, since these may significantly differ from laboratory conditions. Furthermore, two different inclinations and three different locations were studied. Significant differences were observed between inclinations (horizontal and vertical) and between locations with different contamination levels (Barcelona city, Natural Park of Montseny and Ghent city). Better results were obtained with horizontal specimens in terms of predominant genus diversity as well as quantitative level of colonisation. Moreover, specimens located in urban areas (Barcelona city) showed also better results. However, the environmental experimental programs should be continued over a longer time span to reach more conclusive results
Intercalation mechanism of polycarboxylate-based superplasticizers into montmorillonite clays by Pere Borralleras Mas( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

The presence of clays in the sands used for concrete production interferes with the development of the fluidity of concrete, producing an instantaneous slump loss just after batching and the premature loss of fluidity. This interference occurs with all types of additives and clays but is especially problematic when combining sands containing expansive clays such as montmorillonites with new-generation high water-reducer/superplasticizer admixtures based on polycarboxylate polymers (PCE).Water-reducers based on PCE polymers offer much better performance than traditional superplasticizers based on sulfonated naphthalene polymers (BNS) and sulfonated melamine polymers (MNS), making great advances in concrete technology, both from the technical and economical point of view as in reducing the environmental impact associated to concrete. However, these advantages are inhibited when sands contain clays of the expansive type in their composition.All the preventive or corrective measures to mitigate the harmful effect of clays contained in sands result in increases of production costs and in greater environmental impact. For this reason, during the last years it has been tried to develop polymeric structures that offer the same benefits than polymers PCE but with improved tolerance against clays of the expansive type, such as montmorillonite clays, but without getting to reach solutions with guarantees of success, due to the complexity of the interaction process between PCE polymers and montmorillonite clays.This doctoral thesis aims to deepen knowledge about the mechanism of interaction between PCE polymers and montmorillonite clays, assuming that the deep understanding of the interaction mechanism is the essential previous step to finally develop high-performance, clay-insensitive superplasticizers for concrete. For this, the research is structured in three parts, motivated by the discrepancies that the current model of interaction proposed shows with the experimental results of sorption and fluidity loss. In the first part, it is intended to develop a test method that allows to observe the real expansion profiles of the clays in such a way that the mentioned discrepancies can be clarified. Secondly, with the proposed test method, it is intended to identify how the structure of PCE polymers, as well as the dosage used, influences on the expansion of montmorillonite clays produced by the absorption of polymer. And, thirdly, to identify how the properties of clay affect the interaction process.The first phase of the research campaign has made it possible to propose an improved test method for the d-spacing determination that revealed the real intercalation behavior, by which the number of PCE side chains intercalated into the interlaminar space of montmorillonite clays is up to ten times higher than that deducted from the traditional analytical method. And from the new test method proposed it has been possible to clarify the role of the different structures of PCE polymers and the properties of montmorillonite clays in the intercalation mechanism, in agreement with the experimental results of fluidity loss and of sorption behavior.Based on the mentioned achievements, an extended model for the intercalation mechanism has been proposed, whereby montmorillonite clays inhibit the dispersing capacity of PCE polymers, being able to identify the parts and properties of both the clay and the PCE polymers that control this process.With this contribution, the knowledge of the intercalation mechanism is extended to understand how the interaction between PCE polymers and montmorillonite clays is developed, which is the main objective of this research

Evaluación de la durabilidad de piezas de trencadís mediante ensayos no destructivos by Mireia Molist Porta( )

1 edition published in 2014 in Spanish and held by 1 WorldCat member library worldwide

El trencadís es una técnica muy utilizada en la obra de Gaudí y también se utiliza en los pináculos de la Sagrada Familia, dónde se empezó a detectar cierto proceso de deterioro. Por esta razón se optó por reparar las piezas dañadas adhiriéndolas con mortero cola y utilizando un mortero especial también en el rejuntado. En los pináculos de nueva construcción se optó por utilizar un nuevo sistema constructivo y el material base es hormigón con fibras. Ante la afectación de las piezas de trencadís por procesos de deterioro, surge la necesidad de conocer la pérdida de adherencia y determinar su estado. En el caso de estudio se optó por acelerar el proceso mediante la aplicación de ciclos de envejecimiento acelerado en laboratorio que reproducen los efectos producidos en una exposición natural, pero de forma acelerada. Se utilizan ciclos de choque térmico, de mojado y secado, de hielo y deshielo y de cristalización por sales en dos tipos de probeta: de reparación y de nueva construcción. Estas probetas tienen las mismas características que el trencadís en los pináculos en ser reparado y que los pináculos de nueva construcción. Es necesario la realización de ensayos para poder evaluar el proceso de deterioro de las piezas a lo largo de la aplicación de los distintos ciclos de degradación. Para ello se utiliza ensayos no destructivos de ultrasonidos y de cámara termográfica. Una vez conocido el estado de la adherencia con el paso de los ciclos, es de vital interés obtener una equivalencia de estos resultados con los efectos producidos de forma natural. De esta forma será posible predecir el deterioro de las piezas en la obra y realizar un plan de reparación y mantenimiento eficaz
Propuestas metodológicas para la caracterización de testigos de presas con problemas expansivos by Eduardo E Fernández de Castro Suárez( )

1 edition published in 2012 in Spanish and held by 1 WorldCat member library worldwide

[ANGLÈS] Some of the dams built in the region of Cataluña, have expansive processes that take place within its concrete, which is the case of the Graus dam. In this dam, observed movements are related in previous diagnoses to an internal sulfate reaction caused by the oxidation of iron sulfides present in the used aggregates. However, numerical simulations of the movements of the dam indicate that there may be a second expansive mechanism, delayed in time, which also contributes to these damages. With that in mind, the objectives of this study are to develop a methodology that serves as a general proposal to characterize concrete cores in dams, and also make a new diagnosis of the Graus dam to determine the reactions that effectively contributes to the expansion process. To do this, visual inspection was performed first, then critical areas in the dam where identified from the point of view of the damage. In these areas, extraction of concrete cores were realized and will be used in an extensive characterization process (visual inspection, selective dyeing, characterization of porosity, ultrasound tests and determination of permeability in O2) to confirm the real causes of the expansion. The results obtained in this study will serve as the foundations for more accurate diagnosis of the behavior of the Graus dam
Evaluación de la capacidad de hormigones reforzardos con fibra de carbono para sensorizar esfuerzos mecánicos by David Enrique Valverde Burneo( Book )

1 edition published in 2019 in Spanish and held by 1 WorldCat member library worldwide

Los hormigones reforzados con fibra de carbono presentan mayor conductividad eléctrica que los hormigones convencionales. Eso facilita la aparición de nuevas propiedades, entre ellas la piezoresistividad. Esta propiedad permite que el material, frente a la aplicación de un esfuerzo mecánico, module la variación en su resistividad dependiendo de la intensidad del esfuerzo mecánico. El presente TFM evalúa diferentes hormigones reforzados con fibra de carbono y su respuesta frente a esfuerzos mecánicos

Diseño de hormigones con porosidad controlada by Cristina Fernández Rubio( )

1 edition published in 2013 in Spanish and held by 1 WorldCat member library worldwide

La dosificación de una mezcla de hormigón o mortero resulta una tarea de gran importancia debido a las consecuencias que puede comportar el no realizar correctamente dicha dosificación. Desde la antigüedad se han usado mezclas de materiales por tal de obtener materiales más durables y resistentes o con alguna propiedad determinada, como podría ser una disminución del peso del material endurecido o el fraguado bajo el agua. Toda esta evolución ha llevado a que actualmente el hormigón sea el material por excelencia en cualquier tipo de estructura. El problema principal que tiene este material es la durabilidad frente a distintos ambientes o acciones externas, ya sean físicas o químicas. Es por este motivo por el que es necesario obtener mezclas durables que no resulten fácilmente atacables. Por una parte esto se consigue mediante las propiedades de los materiales, ya que se escogen en función de la idoneidad del uso, por otra parte la dosificación de la mezcla determina las características finales del elemento endurecido, y es por este motivo por el que hay que dar gran importancia a este proceso. Actualmente existen muchos métodos de dosificación, cada cual aporta nuevas variables a considerar en el proceso, o amplia el rango de hormigones que pueden ser dosificados con dicho método. De igual manera, las investigaciones que se han llevado a cabo durante los últimos años referentes a las características de los hormigones, han permitido introducir en las normativas valores recomendados de algunos de los componentes o relaciones (cantidad de cemento o relación a/c). Igualmente las normas determinan las características que han de presentar estos materiales para no comprometer la durabilidad durante la vida útil. En esta tesis se ha investigado la importancia que tiene la relación a/c, el contenido de pasta y la granulometría, así como la relación entre las tres variables, para poder obtener de una manera sencilla unos primeros valores de estos para cualquier dosificación. Durante la campaña experimental se han realizado ensayos de porosidad, absorción, desorción y resistencia, así como un análisis de imagen de las secciones interiores de cada una de las probetas realizadas. Finalmente, se han obtenido una serie de conclusiones que han permitido acometer lo enunciado en el párrafo anterior en cuanto a los valores de cada una de las variables analizadas
New insights on the fundamentals and modeling of the external sulfate attack in concrete structures by Tai Ikumi Montserrat( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

The external sulfate attack (ESA) is a complex degradation process typically compromising the durability of underground foundations, nuclear or industrial waste containments and tunnel linings exposed to sulfate solutions. The structures affected usually remain covered its entire service life, which compromises the detection of this phenomenon before severe material degradation has occurred. Once diagnosed, the large size and criticality of the typical structures affected greatly limit the efficiency of the remedial actions. Consequently, monitoring of the evolution of the structural behavior is often the only applicable measure. This scenario places the development of reliable tools to assist the design of sulfate-resisting concrete structures and assess the risk of ESA in existing properties as key challenges for structural durability. The present thesis aims to advance knowledge in this field by presenting important contributions in three different research lines: numerical modeling of the ESA, role of porosity during the attack and the relevance of reproducing field-like conditions on ESA assessments. Advances on the ESA numerical modelization led to the development of a chemo-transport-mechanical model and a simplified assessment methodology. The former simulates the effects of ionic transport, chemical reactions, degradation mechanisms and the mechanical response of the structure. The validations performed indicate that the model captures the importance of the location of the ettringite formed within the pore network and provides a fair quantification of the overall expansions. The simplified assessment methodology evaluates the risk of failure during the ESA based on the aggressiveness of the media, the reactivity and mechanical properties of the material and the geometric characteristics and service life of the element under attack, without resorting to complex iterative algorithms. Unlike current design guidelines, the application of this simplified procedure allows the definition of flexible and optimized precautionary measures for each application. The second research line involved an extensive experimental program that led to the formulation of a conceptual model to explain the role of porosity during the ESA. The results obtained indicate that high durability against the attack might be achieved by limiting the penetration of sulfates or increasing the capacity of the matrix to accommodate expansive products. Both approaches correspond to opposing pore characteristics of the matrix: the former is usually associated with low porosities while the latter requires matrices with high porosities. These results question the common perception that high porosities are always negative for ESA durability and open up the possibility to design sulfate-resisting materials by increasing the capacity of the matrix to accommodate expansive phases. The third research line evaluates the influence of early sulfate exposure and the effects of confinement on the ESA by two experimental programs. The first study suggests that the delayed exposition to sulfates commonly adopted in accelerated laboratory tests might lead to imprecise damage estimations for structures cast in situ. In these cases, it is recommended to expose the samples to sulfates shortly after casting. The second study suggests that assessing sulfate resistance on specimens in free-expanding conditions might not be representative of the behavior of real structures where the attack is developed in combination with confining conditions. Results indicate that compressive stresses generated by confinement interact with the normal development of the attack by limiting or delaying the appearance of micro-cracks and reducing the amount of ettringite crystals exerting expansive pressures
