Effect of rice husk ash on physical, mechanical, and hydric properties of clay-based geopolymer
Soungalo Ouattara, Youssouf Sawadogo, Moustapha Sawadogo, Brahima Sorgho, Mohamed Seynou, Philippe Blanchart, Lamine Zerbo
This study explores the production of geopolymer using a mixture of rice husk ash (RHA), clay and a local alkaline activator. To emulate previous research, the bricks are formulated for thermal curing at 60 °C for 24 h. The formulation of geopolymers incorporates varying mass percentages (0 %, 5 %, 10 % and 15 %) of RHA. The results of physica(...)

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(...)

Preparation and Characterization of Clay Soils for Applications in Cyanide Removal from Mining Wastewater
Raymond Kaboré, Yacouba Sanou, Rasmane Tiendrebéogo, Alassance Compaoré, Adama Konaté, Samuel Paré
In Burkina Faso, water resources in mining areas are polluted by cyanide, which is released into the environment through mining activities. To mitigate this pollution, two clays named Koro and Kaya were collected in Burkina Faso and characterized using analytical technics. This work aimed to find out a cheap technology based on local soils for(...)

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(...)
