Sustainable dam sediment management is one area of the circular economy, which aims to optimize resources and reduce environmental impact through innovative eco-friendly solutions for environmental preservation and resource recovery. This study is a laboratory investigation of the Bir M’Cherga dam sediment (S) to determine its physical, geotechnical, environmental, structural, and thermal characteristics to investigate the possibility of reuse as a ceramic material. Geotechnical properties show that the sediment is a highly plastic clay composed of 6% clay, 50% silt, and 44% sand. Environmental characterization classifies the sediment into low organic matter, and the structural and physical characterizations revealed that (S) contains primarily calcite, quartz, kaolinite, and illite. X-Ray Fluorescence Spectrometry (XRF) revealed that the most abundant oxides are SiO₂, Al₂O₃, Fe₂O₃, and CaO, while SO₃, MgO, and alkali (K₂O, Na₂O) are only present in small quantities. Infrared spectroscopy (FTIR) results show relatively broad absorption bands localized around 3500 cm-1, associated with phyllosilicates such as kaolinite and illite. Dilatometric analysis indicates a sintering start temperature of 1025°C. This characterization identifies the potential utilization of sediment in ceramic applications, including tiles and bricks, in accordance with circular economy principles.

摘要

Sustainable dam sediment management is one area of the circular economy, which aims to optimize resources and reduce environmental impact through innovative eco-friendly solutions for environmental preservation and resource recovery. This study is a laboratory investigation of the Bir M’Cherga dam sediment (S) to determine its physical, geotechnical, environmental, structural, and thermal characteristics to investigate the possibility of reuse as a ceramic material. Geotechnical properties show that the sediment is a highly plastic clay composed of 6% clay, 50% silt, and 44% sand. Environmental characterization classifies the sediment into low organic matter, and the structural and physical characterizations revealed that (S) contains primarily calcite, quartz, kaolinite, and illite. X-Ray Fluorescence Spectrometry (XRF) revealed that the most abundant oxides are SiO₂, Al₂O₃, Fe₂O₃, and CaO, while SO₃, MgO, and alkali (K₂O, Na₂O) are only present in small quantities. Infrared spectroscopy (FTIR) results show relatively broad absorption bands localized around 3500 cm-1, associated with phyllosilicates such as kaolinite and illite. Dilatometric analysis indicates a sintering start temperature of 1025°C. This characterization identifies the potential utilization of sediment in ceramic applications, including tiles and bricks, in accordance with circular economy principles.
