AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...
In Switzerland, the peak period for the construction of large hydropower plants dates back than 50 years ago. Only in the '80s a reaction was discovered, which generates internal swelling of the concrete and causes permanent damage to the structures. The r ...
In this paper, the applicability of the Partial Safety Factor Format (PSFF) of EN1992-1-1:2004 (Eurocode 2 for Concrete Structures) to the reliability verification of structural concrete resistance involving multiple failure modes is investigated. This is ...
By studying approximately a century of cement and concrete in Switzerland, this project examines the relations between institutions, discourse, and technology as they intersect in the material. The project is framed so that the establishment of organizatio ...
The compressive resistance of concrete in new structures is usually characterized on the basis of tests performed on concrete cylinders or cubes under relatively rapid loading conditions. Although efficient for material characterization, these tests do not ...
The use of cement and concrete, among the most widely used man-made materials, is under scrutiny. Owing to their large-scale use, production of cement and concrete results in substantial emission of greenhouse gases and places strain on the availability of ...
This contribution gives an account of how concrete construction developed in French-speaking Switzerland since the end of the nineteenth century. The narrative is based on original sources from the Archives de la construction moderne (Acm) and on data and ...
Looking back at the history of concrete houses around 1900, we can discover how reinforced concrete, initially tied to construction systems of renowned inventors (and other less known), is gradually becoming autonomous and a material on its own, highlighte ...
“Structural UHPFRC” stands for Ultra-High Performance Fiber Reinforced Cementitious Composite material that is complemented by reinforcing and prestressing steel to enhance the resistance and durability of structural elements. Properties of impermeable, te ...
In this paper, a model to analyze the propagation of intentional electromagnetic interferences disturbances along penetrating conductors into concrete walls is proposed. The model is based on the transmission line theory and considers the attenuation of th ...
