コンゴ民主共和国カナンガの採石場から採取した3種類の粘土質砂質土壌（黄、赤、黒）を、セメントや焼成レンガの代替となる日干しレンガ建築用の地盤材料として評価。高塑性、カオリナイト質、石英含有などの特性を明らかにし、生態学的住宅への可能性を示すが、機械的試験は今後の課題。
English
This study evaluates three clayey-sandy geomaterials (yellow, red, black) from Kananga, DRC, for earthen construction as an alternative to cement and fired bricks, which are major CO2 sources. The materials show high plasticity, kaolinitic composition, and quartz content, indicating potential for ecological housing, though mechanical testing is still needed.

📄 Abstract（原文）
The construction sector must consider a transition away from cement and fired brick, which are major sources of carbon dioxide (CO₂) emissions responsible for global climate change and contributing to deforestation in the Democratic Republic of Congo (DRC). In this context, the adoption of local geomaterials for earthen construction appears not only strategic but also highly relevant. This article presents three types of clayey-sandy geomaterials, identified by their color (yellow soil, red soil, and black soil), extracted from the Nganza quarry in Kananga, in the Kasai-Central province of the Democratic Republic of Congo. We examine their suitability for earthen construction from an ecological perspective. The three materials analyzed are characterized by their fineness and high plasticity (plasticity indices ranging from 30 to 52%), their kaolinitic state and quartz content, as well as their color, which is influenced by the presence of iron oxides and organic matter. This study highlights the potential of these geomaterials, which still require adjustments and mechanical testing, and underlines their relevance for the development of ecological housing in the city of Kananga.
