Phase field modelling of the microstructure originated during redox reactions in metal-metal oxide systems Ghent University
The redox reactions in a metal-metaloxide system are modelled with a phase field model, which incorporates diffusion, thermodynamics and electrochemical reactions. The required input variables are obtained by coupling the model to 2 thermodynamic databases and by execution of specific experiments to determine these parameters. Experiments are also used to verify the predictive nature of the model.
Carbonation performance of concrete with recycled aggregates and hybrid binders Ghent University
Greenhouse gas emissions associated with concrete production represent about 5% of the total volume of anthropogenic emissions Eco-efficiency of concrete can be achieved through partial replacement of Portland cement by supplementary cementitious materials (SCMs), and by utilizing recycled aggregates The amount of SCMs that can be used in concrete production is limited; however, it can be increased when alkaline additives (referred to as ...
Integrating the future in life cycle assessment? An ex-ante case study of emerging innovative slag treatment technologies. University of Antwerp
Raman Microscope for Sustainable Inorganic Materials Management (Raman-SIM2) KU Leuven
The Raman-SIM2 project involves a Raman spectrometer coupled to a microscope (Raman microscope) that is specifically designed to study the mineral phases in geological and metallurgical samples, with emphasis on (low-grade) ores, metallurgical slags, mine tailings, geopolymers and industrial process residues. The main goal is the qualitative and quantitative characterization of inorganic materials (solids, liquids and gases) on ...
Assessment of the Carbonation, CO2 Sequestration and Leaching Behavior of Potential ‘Green’ Concrete with Supplementary Cementitious Materials to Quantify its Actual Durability and Sustainability Ghent University
Partial cement replacement by supplementary cementitious materials in concrete could reduce CO2 emissions. Durability should remain though. Because accelerated tests usually indicate higher susceptibility to carbonation, all related changes in microstructure and transport properties will be studied. Moreover, a setup for carbonation under mechanical loads will be developed. CO2 sequestration and leaching will be addressed as well for LCA ...
