Effect of the nature of clay and substitution materials on physico-mechanical properties of compressed earth blocks (CEBs)

Philbert Nshimiyimana (PhD Researcher); Adamah Messan; Prof. Luc Courard(Supervisors)

The mechanical and hydrothermal performances of compressed earth blocks (CEBs) are essential for improving housing quality and comfort in Sub-Saharan countries and, specifically, Burkina Faso. Earth stabilization, using two by-products available in Burkina Faso: Calcium Carbide Residue (CCR) and Rice Husk Ash (RHA), improves the performances of CEBs. The effect of addition of CCR and/or CCR partially substituted with RHA (CCR: RHA) to the clayey earth is investigated. The physico-chemical and mineral properties of raw materials: clay material and by-products are characterized. Various mixtures are formed with earth and 0 to 25 wt. % CCR and/or CCR: RHA (various ratios). The results shows the improvement of the mechanical performance on basis of the compressive strength of CEBs and the acceleration of the interactions in mix solutions on the basis of rapid decrease of electrical conductivity (EC)  and concentration of  unconsumed calcium ion [Ca2+]. The reaction resulted in the formation of Calcium Silicate Hydrates (CSH) and Calcium Aluminate hydrates (CAH). More.

Regulation regimes for the development of hybrid places: a cross-european comparative analysis (01/2017 - 12/2018)

Constance Uyttebrouck (chercheuse doctorante), Jacques Teller (promoteur)

The research project addresses the effects of labour market mutations on housing through the comparative analysis of “spatial hybridization” in three Northern European cities. “Spatial hybridization” conceptualizes spatial mutations and innovative practices lying in between housing, the labour market and urban development. This concept emerges in a global context affected by the advent of ICT, particularly in the labour market, in which the development of NWOW has led to the flexibilisation of space and practices. This has been transforming the Corporate Real Estate since the 1980’s, with e.g. the development of the so-called shared “Activity-Based Workplace”, as well as co-corking spaces. Plus.

Cyclic behavior of XL monopole in clayey soils (octobre 2016 - décembre 2017)

 S. Ahayan (PhD researcher), F. Collin (Promotor; ULiège), P. Kotronis (Co-promotor; École Centrale Nantes)

The main objective of this project is to study the soil- foundation interaction for XL monopiles under lateral and cyclic loading, by taking into account the typical dimensions of XL monopiles. We focus, therefore, on the numerical modeling of soft clay behavior and of the soil/pile interface. We aim to develop a new constitutive law for clayey soil and a new interface constitutive model. This will allow developing new p-y curves that could be widely applied in offshore wind energy industry. More.

Gypsym residues in recycled materials: effects on microstructural and mechanical properties of cementitious mixes

Ch. Colman (PhD researcher), L. Courard (Promotor)

This PhD research is part of the INTERRG VALDEM project. It aims to research how much residual gypsum contamination from demolition waste is acceptable for designing new concretes. Providing a better understanding of the effects of sulphate attack in the context of demolition waste will promote the valorisation of these recycled materials in the building sector. More.

INTRAS: Inégalités en sécurité routière / Inequalities in traffic safety (octobre 2013 - décembre 2017)

Mario Cools

In health research extensive evidence is found on socioeconomic and cultural differences on health outcomes. One of these health concerns are traffic injuries which impact is expected to increase worldwide. As in other health domains inequalities are found in accident involvement. Again underprivileged groups are the most vulnerable. Injury research however still lacks explanatory models on how contextual and individual factors contribute to injury causation. The main objective for this study is therefore to reveal some of these mechanisms that explain the differences that occur in road accident involvement in Belgium. More.

REDMONEST-BE2: Réseau de monitoring dynamique des structures existantes du Patrimoine Culturel en béton

Luc Courard

L’objectif principal du projet est de développer un système de gestion en temps réel pour évaluer le processus de corrosion du béton ancien exposé au vieillissement naturel (y compris plusieurs mécanismes de vieillissement tels que la carbonatation et les chlorures induisant la corrosion, ainsi que l'impact climatique). Ce système fournira les capacités d'auto-adaptation à différents types de patrimoines et intègre des capteurs. Plus.
