Valorization of Glass Bottles in the Manufacture of Fired Compressed Earth Bricks (CEB)
Talardja Diadi, Youssouf Sawadogo, Brahima Sorgho, Moustapha Sawadogo, Mohamed Seynou, Lamine Zerbo, Philippe Blanchart
The building materials commonly used are energy-intensive, non-ecological, and unsuitable for climatic conditions. For this reason, various research projects have been initiated to develop efficient, appropriate, and accessible building materials. Much of this research focuses on valorizing local materials and available waste. In our study, la(...)

Phase diagram and deuteration contribution to the phonon analysis of the normal-to-incommensurate phase transition of 4-4′ dichlorobiphenyl sulfone determined using Raman and neutron scattering
M. Sougoti, F. Le Marrec, S. Beaufils, J. Ollivier, P. Bourges, B. Toudic, and C. Ecolivet
4-4′dichlorobiphenyl sulfone (BCPS) presents a phase transition from a high-symmetry monoclinic phase 𝐼2/𝑎 to an incommensurate phase 𝐼2/𝑎 (0β0) at 𝑇i=150 K without any lock-in phase transition observed down to the lowest temperatures at atmospheric pressure. Such examples which remain incommensurate close to 0 K are quite rare and are proto(...)

The Removal of As(III) Using a Natural Laterite Fixed-Bed Column Intercalated with Activated Carbon: Solving the Clogging Problem to Achieve Better Performanc
Régie Dimanche Ouedraogo, Corneille Bakouan, Abdoul Karim Sakira, Brahima Sorgho, Boubié Guel, Touridomon Issa Somé, Anne-Lise Hantson, Eric Ziemons, Dominique Mertens, Philippe Hubert and Jean-Michel Kauffmann
Natural laterite fixed-bed columns intercalated with two types of layers (inert materials, such as fine sand and gravel, and adsorbent materials, such as activated carbon prepared from Balanites aegyptiaca (BA-AC)) were used for As(III) removal from an aqueous solution. Investigations were carried out to solve the problem of column clogging, w(...)

Manufacture of Industrial Refractory Crucibles Based on Clays from Burkina Faso, Journal of Minerals and Materials Characterization and Engineering
Kassoum Barry, Youssouf Sawadogo, Moustapha Sawadogo, Brahima Sorgho, Mohamed Seynou, Boubié Guel, Philippe Blanchart, Lamine Zerbo
In Burkina Faso, one of the three largest gold producers in West Africa, foundry activity is often paralyzed when basic equipment such as crucibles and cups are not available or should be imported. However, previous studies have shown the availability of kaolinite-rich clay resources that could be used for the local manufacture of silico-alumi(...)

Preparation and characterization of foamed concrete using a foaming agent and local mineral resources from Burkina Faso.
Alassane Compaoré, Moustapha Sawadogo, Youssouf Sawadogo, Moussa Ouedraogo, Brahima Sorgho, Mohamed Seynou, Philippe Blanchart, Lamine Zerbo,
The paper describes lightweight-foamed concretes (LFC) that were formulated from cement, natural sand, and
foam from a foaming agent with densities of 600 and 700 kg/m3. The identified mineral phases in the cement are
alite, belite, Celite, ferrite, calcite, and gypsum. The obtained foamed concretes have a porosity varying from
29.17 to 37.(...)
