Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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 aim of this thesis was to synthesise and control a nanostructured composite of copper/cobalt. Both the copper and cobalt oxalate exhibit a nanostructure. Attempts to produce nanocomposite particles in the size range of 10-70 nm were made via an oxalate ...
The ignition delay times of CH4/C2H6/C3H8 mixtures representative of an average natural gas composition have been measured in a rapid compression machine (RCM) at the University of Lille. The pressure at the end of compression (EOC) varied from 13 to 21 ba ...
Self-levelling flooring compounds (SLC) are applied in thin layers (less than 1cm) to level floors before further finishing cover such as parquet or plastic cover. They are composed of a ternary binder system based on Portland cement (PC), calcium aluminat ...
The chemical stability of bacteriogenic “UO2” is one of the seminal issues governing its success as an in-situ waste form in remediated subsurface locations. Little detail is known about the structure and reactivity of this material, but based on compariso ...
The synthesis of the alkoxide [OC(tBu)(CF3)2]− by the reaction of tBuM-reagents (M = Li; MgX) with hexafluoroacetone was attempted. This alkoxide was anticipated to be a good building block for novel weakly coordinating anions. However, in all attempted sy ...
The applications of systems based on Portland Cement (PC), Calcium Aluminate Cement (CAC) and Calcium Sulphate (C$) are usually limited to indoor uses in the field of Building Chemistry because no durability data exist on the outdoor uses. These ternary bi ...
Impure tricalcium silicate (Alite, C3S) is the most important and abundant phase of Portland cement. It reacts quickly with water to give calcium hydroxide (CH) and calcium silicate hydrate (C-S-H) which is the most important phase for strength development ...
The influence of the presence of limestone on the hydration of Portland cement was investigated. Blending of Portland cement with limestone was found to influence the hydrate assemblage of the hydrated cement. Thermodynamic calculations as well as experime ...
The formation of thaumasite was investigated with the progressive equilibrium approach (PEA). This approach experimentally simulates the conditions of various levels of sulfate addition in hardened cement pastes. The influence of limestone, time, C(3)A con ...
An important mode of hydration of Ordinary Portland cement (OPC) is via the formation of a shell of hydration products around cement grains. It has been shown so far that shells form not only in OPC but also around C3A grains in a mixture of alite, C3A and ...
