“…In recent decades, researchers and engineers have proposed numerous methods for the improvement of the mechanical properties of soils through mechanisms that are more environmentally friendly [40][41][42][43], i.e., the use of polypropylene [44], tire strips [45], crushed tires [46]; as well as the addition of artificial and natural fibers, such as fiberglass [7], coconut shell [47,48]; water hyacinth [49], palm fibers [50], jute [51], Kernel palm shells [5]; rice husk ash [52]. Similarly, some research has been observed on the use of electronic waste (e-waste) in activities to improve the engineering properties of soils [53,54].…”

A frequent problem in Geotechnics is the soils with inadequate physical-mechanical properties before the efforts to which they will be subjected by the constructions, incurring cost overruns caused by their engineering improvement. The need to improve the engineering properties of soils is not recent, currently observing that the most common alternatives are binders such as cement and lime. The climate change observed in recent decades and the uncontrolled emission of greenhouse gases have motivated Geotechnical and Geoenvironmental researchers to seek mechanisms for soil reinforcement from a more sustainable and environmentally friendly approach by proposing the use of recycled and waste materials. An alternative is natural fibers, which can be obtained as waste from many agro-industrial processes, implying their high availability and low cost. Sawdust as a by-product of wood processing has a rough texture that can generate high friction between the fiber and the matrix of the soils, leading to a significant increase in its shearing strength and bearing capacity. This concept of improving the properties of soils using natural fibers distributed randomly is inspired by the natural phenomenon of grass and/or plants that when growing on a slope can effectively stabilize a said slope.

“…Hence, various projects, such as roads, rails, channel structures and foundations that are constructed on expansive soils, may be subject to contraction stress because of unexpected variations in soil volume, which might lead to cause fractures and significant loss (Ikeagwuani and Nwonu, 2019). Geotechnical engineers have been utilizing various techniques to decrease expansive-soil influences by practicing soil stabilization (Atahu et al, 2019;Garg et al, 2021;Hamza et al, 2022;.…”

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.

“…Based on the size of particles, there are four types of soils: gravels, sands, silts, and clays [6]. Clays present the worst physical and mechanical properties due to their moisture content [7][8][9], during changes in weather conditions [10].…”
