Item Performance of Earth Blocks Based on Recycled Dam Sediment and Reinforced with Alfa Fibers : Experimental Study(Taylor and Francis, 2025) Gueffaf, Nezha; Rabehi, Bahia; Boumaaza, Messaouda; Boumchedda, Khaled; Belaadi, Ahmed; M. S. Abdullah, Mahmood; Klimkina, Iryna; A. al-Lohedan, Hamad; Al-Khawlani, Amar; Chetbani, YazidRiver and dam dredged sediments are regarded as waste. Waste sediment disposal involves financial resources and raises issues regarding the environment. Reusing dredged sediments to make building materials like adobe bricks can offer an alternative way to handle and value this waste. Compressed earth blocks (CEB) are environmentally friendly building materials made from clay soil or sediments dam with fibers. Natural fibers addition improves mechanical and thermal characteristics of adobe bricks. The goal of this study was to use Alfa fibers (AF) from Algeria to create adobe bricks from the sediments of the Koudiat Acerdoune dam. This study presents an experimental study of earth blocks stabilized with 10% cement and reinforced with AF fibers at different volume fraction dosages (0.75%, 1.5%, and 2.5%). The new composite of these sediments’ capillary absorption, shrinkage, compressive strength, flexural strength, and thermal conductivity was examined. With a flexural strength of 2.30 MPa and a compressive strength of 8.12 MPa for 2.5% AFs, as well as a decrease in thermal conductivity, the fiber/cement formulations demonstrated the best mechanical performance, according to the results of the analysisItem Modeling a Composite Reinforced with Short Alfa Fibers to Determine its Fatigue and Structural Homogenization(Springer, 2018) Nour, Abdelkader; Mechakra, Hamza; Benkoussas, B.; Tawfiq, I.; Settet, A. T.; Renane, R.The fatigue and homogenization of polypropylene reinforced with untreated and chemically treated short Alfa fibers were investigated using a modified Mori–Tanaka model. The polypropylene with chemically treated fibers showed a higher resistance than that with untreated ones. Cylindrical fibers with elliptical cross sections were used in experiments. Their mechanical characteristics were determined by the inverse method.Item Novel biocomposites based on sunflower oil and alfa fibers as renewable resources(Springer, 2018) Kadem, Sihem; Irinislimane, Ratiba; Belhaneche-Bensemra, NaimaItem Novel biocomposites based on sunflower oil and alfa fibers as renewable resources(Springer, 2018) Kadem, Sihem; Irinislimane, Ratiba; Belhaneche-Bensemra, Naima
