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.

A frequent problem in geotechnics is soils with inadequate physical–mechanical properties to withstand construction work, incurring cost overruns caused by their engineering improvement. The need to improve the engineering properties of soils is not recent. The most common current alternatives are binders such as cement and lime.

“…It is noted that those materials are preferable in terms of cost [4]; and they also save the environment from pollution in terms of their disposal [5]. Sawdust are made from the processing of wood for construction and other industrial purposes, and increases the undrained shear strength of clayey soil when added [6] Saw dust is a byproduct of sawmills created when cutting wood. Loose debris or wood chips are produced when cutting wood into valuable pieces.…”

Infrastructural development on unstable clayey soil has resulted to the damage of buildings and roads, the loss of lives, and financial instability in many projects including both vertical and horizontal structures due to the incapability of clayey soil to withstand certain magnitude of loadings. Furthermore, the deposit of materials that are left-over in open areas has also become an environmental challenge for residents in many communities. This review elaborates on the effect of waste materials—SDA (sawdust ash), FA (fly ash), and RHA (rice hush ash)—on the shearing strength of clayey soil as agents for stabilization. The study covers significant books on stabilizing clayey soil with additives as well as high indexed research articles that were published from 1998 to 2023. The findings show that, mixing the ash of sawdust with natural clay soil at the peak values of four (4) percent to seven point five (7.5) percent carries up the UCS (Unconfined Compressive Strength), the MDD (Maximum Dry Density), the CBR (California Bearing Ratio), and lowers the soil’s swelling, Optimum Water Content or OMC and Liquid Limit (LL). Similarly, the mixture of FA and clay soil at the optimum values ranging from 9 to 25%, raises the clayey soil’s UCS, MDD, and CBR while lowering its swelling potential, OMC, and LL. Additionally, the UCS, MDD and CBR increases, and the swelling, OMC, and LL reduce at the optimum value of added rice hush ash ranging from 10 to 20%. Thus, it is established that the addition of sawdust, fly, and rice hush can enhance clayey soil’s engineering properties.
