“…These materials harm the environment and are created through various industrial processes [20]. Therefore, during the past few decades, numerous researchers have attempted to employ these waste products to stabilize expensive soil, and some of them have even been suggested for use as building materials [21][22][23][24]. The utilization of waste materials for various geotechnical applications and to reduce their environmental impact is now widely recognized.…”

Stabilization of clayey soil is commonly used to enhance unfavorable engineering properties. The effects of silica additives on soil improvement have been considered recently, and documented research studies on the characteristics of problematic clays stabilized by silica additives are interesting for many researchers. Alternative waste disposal strategies that would be both economically beneficial and environmentally friendly have been identified by this study. In the present study, waste silica-based addition is used to stabilize clayey soil, and the time-dependent changes in strength properties are investigated. Unconfined compressive strength (UCS) tests were conducted on stabilized samples at various curing durations to investigate macro-level properties. The UCS test results revealed that the 7.5% of GP+ 5% L content was optimal for the clayey soil as the strength was increased by 166.06%. The addition of the glass powder with hydrated lime components to the clayey soil resulted in stabilized samples, indicating a dense and compact matrix and reduced soil porosity, which increased the mechanical strength, according to the SEM analysis. This curing reaction technique is very beneficial and economical for geotechnical engineering applications.

“…Furthermore, a study by Javed and Chakraborty found that the waste glass powder can enhance the clay soil, according to [24]. As this material is widely and economically available locally, using waste glass for stabilization contributes to reducing the impact on the environment and economical solutions.…”

“…However, the presence of OH groups can improve the intermolecular H‐bond in a polymeric matrix, favoring its conductivity 52 . Salih et al 53 reported electrical conductivity in copolymer carbazole–phenol formaldehyde (c.a 1 × 10 −4 Ohm −1 ), which increased with the addition of at least 0.1 g of dopant reaching values of 0.000595 Ohm −1 .…”

This work aimed to manufacture bioplastics with mechanical and electrical properties for monitoring the Rhizopus stolonifer growth in tomato fruit packaging. Bioplastics were based on chitosan/polyvinyl alcohol (Ch/PVA), chitosan/polyvinyl pyrrolidone (Ch/PVP), and nanoparticles (NPs) of plant extracts at 10% and 30% of concentrations. Bioplastics were exposed to tomato inoculated with R. stolonifer for 6 d at 25°C. Water vapor permeability (WVP), mechanical properties, FTIR, UV–vis, morphology, electrical resistance of bioplastics, and the NPs size were assessed. In bioplastics added with plant extracts, 1.5 times more WVP than in the control group (18–35 gs−1m−1Pa−1) were quantified. Ch/PVA bioplastic showed 51% more tensile strength, 44% more elongation at break, and 40% more Young's modulus than Ch/PVP, regardless of the plant extract. The electrical resistance in Ch/PVA bioplastics with 30% mushroom extract and 10% radish allowed the differentiation between inoculated (109–1010 Ω) and non‐inoculated tomatoes (1010–1011 Ω). The FTIR assay confirmed the presence of each compound used in the bioplastic, and UV–vis confirmed phenols at 300 nm. The NPs measured less than 50 nm. Only Ch/PVA with 30% mushroom and 10% radish can be useful to monitor fungi in tomatoes based on their electrical behavior.

“…It involves the utilization of various types of materials that will be helpful to increase the load-bearing capacity, decrease settlement and improve the soil's durability. Therefore, SFD, which is a byproduct of steelmaking factories, was chosen to be used for soil-stabilization purposes (Bijarniya et al, 2020;Salih & Abdalla, 2022). The process of stabilization has several objectives; namely, soil-strength amendment and soil-resistance increase for softening due to water penetration through bonding the soil particles together, providing waterproofing for the soil particles.…”

One of the geotechnical-engineering roles is soil stabilization, because it affects the long-term strength and functionality of structures. For suitability and durability of expansive soils for construction projects, shear strength, bearing capacity and other characteristics can be enhanced through the stabilization process. This study is focused on the effects of steel factory dust (SFD) as an additive on the improvement of the undesired geotechnical properties of expansive soil (CH soil). A series of laboratory tests were conducted on intact and treated samples. SFD was added by 0, 2, 4, 6, 8 and 10% to the dry soil. The conducted tests are consistency, specific-gravity, modified Proctor compaction, swelling-pressure and -percent and unconfined compression tests. The addition of SFD reduced the values of liquid and plastic limits, plasticity index, modulus of elasticity and allowable bearing capacity. Significantly, the 10% SFD addition significantly reduced swelling percent and pressure by 26.8% and 25.4%, respectively while notably increasing the unconfined compressive strength (UCS) from 475 MPa to 629 MPa. SFD was found to be a successful waste material in improving expansive soil by using 10% as the best addition percent, which usefully saves the environment.
