Development of a differential LAPS-based monitoring system to evaluate the metabolic response of bacteria in biogas process analyses KU Leuven
The independence of fossil fuels as energy carriers is an essential future-oriented aim for all nations around the world. The negative influences of global climate changes are strongly noticeable in our daily life. Reports on unexpected natural catastrophes reach many people and make them contemplative finding proper and novel strategies to overcome related future disasters. In this context, scientific efforts and methodologies are in demand ...
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.
The Rheological and Shrinkage Behaviour of Fe-rich Slag-based Binders KU Leuven
The global anthropogenic CO2 emission, which is considered the main contributor to global warming, is exponentially increasing yearly. The proportion of CO2 emission from construction is around 8-9% and is expected to become more significant in future, as the demand for raw materials in construction, such as ordinary Portland cement (OPC), increases every year. The production of OPC is environmentally unfriendly and the availability of ...
Engineering of slags and residues and development of alkali-activated binders and blended cements for construction applications by means of high-throughput experimentation KU Leuven
As part of the project, the Ph.D. candidate will engineer slags and residues to be used as precursors in alkali-activated binders or blended cement, and develop performance models of the correspondent binders using data obtained from high-throughput experimentation. The Ph.D. candidate will work with slags, which originate from the non-ferrous metallurgy industry or industrial residues from other processes. An in-depth characterization (e.g., ...
Novel Sustainable Binders incorporating High Volumes of Bauxite Residue KU Leuven
Bauxite residue (BR) is the alkaline residue of alumina production with an annual production exceeding that of 150 Mt and a total disposed volume exceeding the 4 Gt. In principle, BR has great potential considering its large availability, however, the use of BR is currently still limited to less than 3% due to its alkaline nature, presence/fear of elevated concentrations of radionuclides, small particle size and low reactivity in a ...
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
Binders and Monoliths from Bauxite Residue (Red Mud) KU Leuven
Bauxite residue (BR), the alkaline waste produced in the Bayer process for the production of alumina is generated in vast amounts and is essentially landfilled on disposal sites. An increasing lack of storage area, several accidents as well as potential risks for health and environment have led to a rethinking in the bauxite residue management. Currently, the reuse rate in the construction sector is approximately 1 %, which is mainly due to ...
