COMPORTEMENT A LA RUPTURE ET CARACTERISATION MECANIQUE DE COMPOSITES POLYESTER-FIBRES DE VERRE

Abstract Water soaking was used to recover fibers from the Djelfa region in southern Algeria, which were then modified with sodium hydroxide at various concentrations (3%, 6%, and 9%) for 5 h at 40 °C. Manual stacking and compression molding procedures were used to create composite samples containing 10 vol % treated and untreated esparto fibers in a polyester matrix. The samples were analyzed using FTIR, XRD, TGA, SEM, and three-point flexural testing. Esparto fibers treated with 9% NaOH demonstrated a 60.39% higher crystallinity index versus raw fibers. Flexural characteristics analysis revealed that composites reinforced with esparto fibers modified with 9% NaOH exhibited superior mechanical performance relative to those containing untreated fibers, with improvements of 47.90% in flexural strength and 48.46% in flexural modulus, respectively. These findings indicate that when chemically treated, Stipa tenacissima fibers hold strong potential as a sustainable alternative to synthetic fibers for reinforcing polymer composites in structural applications.

Foam flotation is a technological process that improves the quality of metals by increasing the content of useful minerals prior to extraction. It is considered the most widely used method for enriching polymetallic ores such as lead and zinc. Calculating the technological flow diagram is a crucial task for the continuation of separation and extraction operations. This calculation requires some initial data.This work addresses the existing problems in the technological flow diagrams for the chemical processing of materials with a high production flow rate (several tons) of concentrate per day. Such a flow diagram requires an analysis of the thermodynamic stability of the minerals themselves, as well as the thermodynamic characteristics of the reactions and their effects on the reactants. The chemical stability of minerals in these technological flow diagrams is conditioned by the energy of their crystal lattices, which depends on a series of factors: such as the type of crystal lattice, the size of the bonds between particles (ions, atoms, and molecules), the types of chemical bonds, and the degree of acidity of the elements. as well as the polarization capacity of actions and anions and other factors.The purpose of the proposed calculation to find the indices of the zinc and lead flotation technology scheme is the continuous and systematic monitoring of flotation reagent consumption and the concentrate productivity of each zinc and lead flotation element. Due to the intensive development of their technology, non-ferrous metals such as copper, lead, zinc, nickel, and aluminum are becoming increasingly scarce, given their usefulness in most industrial enterprises. With the increase in the production of these metals, their reserves in quarries and mines are decreasing, forcing operators to use those remaining stored in tailings piles with low levels of useful lead or zinc products. These metals (Pb and Zn) also concentrate in natural waters. They are naturally present in the environment, resulting from rock weathering processes.This work focuses on the lead-zinc polymetallic ore from a horizontally arranged deposit divided into several workings. Keywords:Metal quality; Flotation; Technological scheme calculation; Lead and zinc concentrate

Abstract Plant fibers are gaining increasing interest as reinforcing materials for polymers due to their sustainability, renewable potential, biodegradability, and light weight, as well as their excellent mechanical and thermal properties, making them promising candidates for environmentally friendly composite applications. This study demonstrates the effects of alkali treatment on woven palm fibers to enhance their suitability as reinforcing materials in polymer composites. Sodium hydroxide (NaOH) was applied at concentrations of 2%, 4%, and 6% for a fixed treatment time of 3 h at room temperature. Chemical analysis revealed a significant decrease in hemicellulose content, resulting in increased accessibility and crystallinity of cellulose (from 53.44% to 62.07%). FTIR and XRD analyses confirmed the removal of amorphous components, which contributed to enhanced fiber stiffness and thermal stability. Tensile testing showed a significant increase in tensile strength (from 158.30 MPa to 233.82 MPa), while TGA results indicated an improvement in thermal resistance, with the decomposition onset temperature rising from 257.24°C to 267.08°C. Scanning electron microscope (SEM) imaging revealed an increase in surface roughness, facilitating better interfacial adhesion to the polymer matrix. Overall, the alkali treatment significantly improves SPF performance, enhancing its potential as a high-performance and sustainable reinforcing material. These results support efforts to optimize natural fiber treatments and develop environmentally friendly composite materials.

Abstract In the context of combating climate change, earth-based construction materials represent a promising alternative to conventional concrete by significantly reducing CO₂ emissions in the building sector. This study provides a comprehensive multi-technique characterization of three distinct clay types (red, green, and yellow) from the Soubella region (M'sila Province, Algeria) to assess their potential for sustainable construction applications. Through integrated geotechnical, physicochemical, mineralogical, and thermal analyses, we reveal significant differences in material behavior. Geotechnical results show that red and green clays are silty-sandy with plasticity indices of 17.3% and 18.55% respectively, while yellow clay exhibits higher plasticity (IP = 25.15%). Mineralogical and chemical analyses indicate that yellow clay contains the highest calcite content (50.35%), compared to green (38.67%) and red clays (24.78%). Conversely, red and green clays are richer in quartz (28.52% and 29.38% respectively). Thermal analysis (25-1100°C) demonstrates how mineralogical composition, hygroscopic behavior, and organic matter content distinctly influence thermal response. These findings demonstrate the strong potential of M'sila clays for manufacturing compressed earth blocks (CEB) and other eco-friendly building materials that align with current environmental standards."
