“…In recent years, several research have been carried out to witness the effect of sawdust powder on the mechanical properties of a variety of soil from different locations. In India the soil studied is black cotton, applying percentages of sawdust powder between 2 and 10% and marble dust between 2 and 10%, resulting in a maximum dry density (MDD) decreased with sawdust and increased with marble dust while the UCS value increased with the addition of marble powder, additionally, the CBR value is greatly improved with the addition of sawdust [105] Other research in India focused on the application of a combined sawdust powder with complementary stabilizers, a combination of sawdust and lime to improve mechanical properties of a marine clay soil from Kakinada region showed a decrease in the plasticity index and an increase in the value of the CBR and the optimal moisture content (OMC) for the value of fiber and binder used were observed [106], additionally the combination of sawdust powder with coir pith to apply in Palakkad soil increases OMC and decreases MDD, expansion pressure, and UCS [107]. In Turkey, research carried out on the application of pine sawdust powder passing the No.…”

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.
