    HOW TO RECYCLE INDUSTRIAL WASTE TO CREATE INNOVATIVE MATERIALS WITHOUT PORTLAND CEMENT.

    In order to create a geopolymer or alkali activated material similar to cementitious materials for chemical and physical study as well as mechanical behavior, the majority of prior research on the terms alkaline and thermal activation was applied in the presence of cement as the main constituent and mixed with industrial waste such as (red brick, slag, ceramic and glass…etc). The solubility of aluminates-silicates can be facilitated by chemical solutions, such as KOH, NaOH and Na2SiO3 or Na2CO3, at varying concentrations. The effectiveness of these methods depends on the nature of the system (CaO-SiO2-Al2O3) in mineral residues. Additionally, there is the thermal method, which involves hardening the material at a temperature difference of 20°C to 80°C for a period of 24 to 48 hours. Studies and researchers have found that all these methods to protect the environment and give perfect solutions to recycler the maximum of the minerals waste for making the alternative binders.

    Identification of the collapse deformation of unsaturated soil susceptible to collapse.

    The soils susceptible to collapse are soils with a porous structure consisting largely of large grains and a small percentage of fine cementation elements. Their moisture content is very reduced because they are located in dry areas, arid and semi-arid. Unsaturated soils with a collapse risk have been a serious concern in geotechnical engineering and provide considerable challenges due to their susceptibility to collapse if moistened, which might result in significant damages. The aim of this work, whose experimental investigation of identification the collapsibility potential of unsaturated soil susceptible to collapse by using the simple consolidation test Jennings and Knight in order to measure the rate at which the collapse potential varies. This experimental investigation used samples of reconstituted soil that are composed of 80% sand and 20% kaolin, compacted with varying energies (15, 30 and 45) hits, and varied moisture contents (2%, 4% and 6%). The experimental results show that our samples exhibited collapsibility with a degree of specimen collapse that was severe and collapse index up to 10%, and that increasing the moisture content and compaction energy reduced the potential of collapsibility to a degree of specimen collapse that was moderate with collapse index less than 6%.

    Examining the effects of cement treatment on the behaviour of an expensive soil

    Saline soil represents one of the biggest challenges in soil science globally and particularly in Algeria, as it occupies a vast area. Many solutions have been proposed to utilize lands affected by salinity for road construction and various other applications. This study aims to improve the properties of the saline soil in the Chott El-Hodna area, specifically in the commune of Ain Al- Khadra, Msila Province, by adding different proportions of cement. The methodology used includes identification tests and mechanical tests. The identification tests included grain size analyses and Atterberg limit tests to evaluate the soil's plasticity before and after treatment. The mechanical tests included Proctor tests, California Bearing Ratio (CBR) tests, and unconfined compression tests to analyse the effect of cement on soil stability and strength. The results obtained demonstrate a significant improvement in geotechnical parameters, notably an increase in compressive strength and a reduction in plasticity. These improvements suggest that the use of cement could be an effective solution for stabilizing saline soils and making them usable in various construction applications.

    Valorization of Industrial Waste for Geotechnical Stabilization: A Sustainable Approach.

    Industrial waste has long posed a critical environmental challenge, as rapid industrialization continues to generate large quantities of by-products that require sustainable management solutions. This study investigates the impact of incorporating industrial waste of aluminum from blast furnaces into collapsible soils on their geotechnical properties. The experimental program evaluates how varying percentages of aluminum waste (5%, 10%, 15%, 20% and 25%) influence Atterberg limits, collapse potential, compaction, California Bearing Ratio (CBR) and shear strength parameters. The findings reveal that the collapse potential of untreated soil decreases markedly from a degree of specimen collapse that was severe to a degree of specimen collapse that was slight when 25% of treatment is added. The shear strength tests demonstrate an increase in cohesion and a reduction in the internal friction angle. Additionally, the liquid limit showed an upward trend, while compaction results indicated a decrease in maximum dry density and an increase in optimum moisture content. CBR results suggest that soil-aluminum waste mixtures are suitable primarily for use in the subgrade layer of pavements. Overall, the reuse of this industrial waste with collapsible soils provides a cost-effective solution for enhancing soil properties, promoting sustainable management of aluminum waste from blast furnaces, reducing natural resource consumption, and minimizing environmental impact through decreased waste retention.

    INVESTIGATING THE IMPACT OF LIME TREATMENT ON THE PROPERTIES OF EXPENSIVE SOIL

    Saline soils pose one of the most significant challenges in soil science worldwide, particularly in Algeria, where they cover vast areas. While various solutions have been proposed to remediate saline lands for construction purposes. This study investigates the potential of lime stabilization to improve the geotechnical properties of saline soil. Results from identification and mechanical tests indicate that the addition of lime significantly enhances the consistency, bearing capacity and compressive strength of the clay, offering a promising solution for the remediation of saline soils.

    Predictive Analysis of Shear Modulus in Geotextile-Reinforced Granular Sand Using Hybrid Modeling Techniques

    This study investigates the improvement of shear strength in sand reinforced with geotextiles through experimental testing. A series of consolidated drained (CD) triaxial compression tests were conducted on sand specimens, both reinforced and unreinforced. The testing program considered varying numbers of geotextile layers (Ng) and different levels of effective confining pressure (σ'c = 25, 50, and 75 kPa). Results showed that the inclusion of geotextiles significantly increased the deviatoric stress (P), enhancing the shear strength of the sand. In addition to the experimental findings, a statistical analysis using analysis of variance (ANOVA) was conducted to assess the significance of the tested parameters. Furthermore, a predictive model based on response surface methodology (RSM) was developed to estimate the reinforced sand’s behavior under different conditions. To further enhance the accuracy of predictions, an artificial neural network (ANN) model was created. The ANN model demonstrated an excellent correlation of 99.69% with the experimental data, indicating its strong predictive capability. In comparison, the RSM model achieved a correlation of 94.54%, reflecting a high level of accuracy but slightly less than the ANN model. This research confirms the positive impact of geotextile reinforcement on the shear strength of sand. It also highlights the utility of ANN and RSM as effective tools for predicting the performance of reinforced soils based on experimental results.

    Characterization Using Non-Destructive Testing (NDT) of SelfCompacting Concrete Made with Recycled Aggregates and Silica Fume

    This study was conducted to address two main concerns, the possibility of formulating Self-Compacting Concrete (SCC) using local materials (recycled aggregates) and the influence of silica fume and limestone fillers dosage on the rheological and mechanical behavior of self-compacting concrete. The objective of this work is to optimize the SCC mix design through the selection of additive type and proportion to improve the mechanical properties of self-compacting concrete (through destructive and non-destructive testing), while maintaining good rheological properties of SCC (filling ability, passing ability, and segregation resistance). The results obtained show that the use of silica fume alone or combined with limestone at a limited rate remarkably improves the performance of recycled SCC containing these additions compared to a control recycled concrete (without fillers).

    ETUDE EXPERIMENTALE DE LA CARACTERISATION DE LA BOUE DE DRAGAGE DU BARRAGE K’SOB EN VUE DE SA VALORISATION DANS LES TRAVAUX ROUTIERS

    envasement des barrages constitue un défi majeur pour la gestion des ressources en eau, particulièrement dans les régions semi-arides comme l'Algérie, où le barrage de K’sob, situé au nord-est de M’sila, subit des pertes annuelles significatives de volume d'eau. Ce phénomène, causé par une érosion actif, nécessite des opérations de dragage fréquentes, qui, bien que nécessaires, engendrent des coûts élevés et des impacts environnementaux Préoccupants. Cette étude vise à caractériser les sédiments extraits du barrage de K’sob afin d'explorer leur potentiel de valorisation dans le domaine du génie civil. À travers des analyses physiques et mécaniques, les sédiments ont été classés. selon le guide technique GTR (LCPC, SERTA, 2000) en classe A2, correspondant à des limons argileux peu plastiques. Ces caractéristiques indiquent que les sédiments peuvent être utilisés efficacement comme matériaux de remblai ou dans les couches d'assise des infrastructures routières.
