Abstract:

Crushed or recycled concrete aggregates (CCA/RCA) is an increasingly popular material as a replacement for natural aggregates in concrete due to industry demands for more recycled, lower carbon and responsibly sourced materials. In the UK, the majority of CCA is utilised in non-structural applications such as: a general fill material, road base/subbase or in low-grade concrete. Recycled aggregate producers however, are seeking new ways to incorporate CCA into higher value applications such as structural concrete to increase profits. Opportunities to incorporate CCA into structural concrete may

Abstract:

Les ciments sulfoalumineux (CSA) peuvent être une solution à l’amélioration de l’impact environnemental des bétons, grâce aux faibles consommations énergétiques et émissions de CO2 lors de leur fabrication. Leurs propriétés expansives, de rapidité de prise et de montée en résistance participent également à l’intérêt grandissant dans les domaines de la construction et de la préfabrication en béton pour ce type de liant. Toutefois, la durabilité des bétons sulfoalumineux reste encore méconnue ou discutée, notamment en milieux acides et face à la corrosion des armatures, en ambiance marine et par

Abstract:

La corrosion des armatures en acier est la plus grande cause de défaillance des ouvrages en béton armé. Ce phénomène électrochimique est déclenché par la présence d’ions chlorure en quantité suffisante au niveau de l’armature ou la carbonatation du béton d’enrobage (action du CO2). L’objectif de cette thèse est de développer des modèles utilisables par l’ingénieur dans une démarche d’approche performantielle pour la prédiction de la durée d’utilisation des ouvrages en béton armé soumis à l’attaque par les ions chlorure ou la carbonatation, suite à l’amorçage et au développement de la corrosion

Abstract:

Presently, durability design of reinforced concrete structures is dealt with in a purely deterministic way and deterioration models have not been developed to their full potential. In particular, researchers who have investigated corrosion and the models currently used to predict the response of concrete, have often overlooked the effect of cracking. Cracks in concrete generally interconnect flow paths and increase the influx of water or aggressive chemical ions into the concrete, facilitating its deterioration. The present research program was undertaken primarily to study the effect o

Abstract:

A harsh, cold, and icy environment is of no surprise to the conditions of a winter climate, where the wide use of de-icing salts on roads and highways allows for the initiation of chloride-induced corrosion of the reinforcement of concrete structures; a reduced service life, loss of structural integrity, visible damages, and ultimately structural failure are among the many unwanted effects of rebar corrosion. Chloride ingress into concrete has been extensively studied for the last four decades; however, most of the relevant research to date does not take into account the effects of sustained l

Abstract:

The specifications for concrete patch repair mortars usually entail mechanical properties such as compressive strength and tensile strength. However, these properties may not directly relate to the desired performance in relation to durability and prevention of reinforcement corrosion. In addition, the literature does not show any direct relationship between compressive strength and durability properties of concrete and mortars in natural exposure conditions. Relevant performance requirements, such as carbonation resistance and chloride resistance, are usually not considered despite the fact t

Abstract:

Reinforcement corrosion has been identified as the predominant deterioration mechanism for reinforced concrete structures (fib, 2006), and is usually caused by carbonation or chloride attack. Chloride- induced corrosion is triggered by an increasing concentration of chloride ions in the pore solution. Corrosion seriously affects the serviceability and safety of concrete structures, and can cause major maintenance costs. Therefore, precise information and understanding of chloride ingress and chloride binding may enable better prediction of service life of concrete structures. The aim of this s

Neste trabalho foi estudada a degradação eletroquímica do azo corante Preto Ácido 210 (PA210) utilizando ânodos dimensionalmente estáveis de composição Ti/Ir0,10Sn0,90O2 e Ti/Ir0,30Sn0,70O2 preparados pelo método de decomposição térmica de precursores poliméricos. Os efeitos da presença e da concentração de cloreto, da composição eletródica, da densidade de corrente e do tempo de eletrólise sobre a oxidação eletroquímica de 100 ppm do corante PA210 foram avaliados. Em todas as condições estudadas, a remoção da absorbância em 465 nm (max) foi superior a 94% depois de 30 min de eletrólise. A red

Emphasis has been given on the particle size effect and nature of aggregates used as raw materials. The present study includes an analysis of the materials that make this kind of concrete, analyzes of mechanical properties such as compressive and tensile strength, in addition t

Abstract:

Inorganic ions are one of the most important group chemicals. Their importance is crucial for all living organisms on the planet and monitoring of their content is essential for this purpose in clinical or environmental analysis but also in the food industry, agriculture or many other industries. Many analytical methods for ion detection have been designed and used, depending on the area of their use. Recently, numerous methods have been adapted to areas where not primarily intended. One such methods may be, for example, laser ablation with inductively coupled plasma mass spectrometry, which h
