“…In Turkey, research carried out on the application of pine sawdust powder passing the No. 4 sieve in Erzurum region soil showed a decrease in the MDD and an increase in the OMC and strength of unconfined compression with the increase in the percentage of sawdust added [1,108,109]; additionally, research carried out adding 1 to 5% of sawdust powder passing No. 20 sieve in Istanbul fine soil showed the strength to unconfined compression increased with the increase in the percentage of sawdust added, showing optima of 3% and 2% respectively, permeability also increased with the increase in the percentage of sawdust added, while the PI, MDD, and OMC decreased.…”

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.

“…Several studies have investigated waste marble powder as a stabilizer for fine-grained soils. These studies have generally found that marble powder can effectively strengthen clayey subgrade and increase its bearing capacity for traffic loads [ 1 , 5 , 8 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. For example, Sivrikaya et al investigated the efficiency of marble powder in stabilizing fine-grained soils regarding volume change.…”

Fine-grained soils present engineering challenges. Stabilization with marble powder has shown promise for improving engineering properties. Understanding the temporal evolution of Unconfined Compressive Strength (UCS) and geotechnical properties in stabilized soils could aid strength assessment. This study investigates the stabilization of fine-grained clayey soils using waste marble powder as an alternative binder. Laboratory experiments were conducted to evaluate the geotechnical properties of soil–marble powder mixtures, including Atterberg’s limits, compaction characteristics, California Bearing Ratio (CBR), Indirect Tensile Strength (ITS), and Unconfined Compressive Strength (UCS). The effects of various factors, such as curing time, molding water content, and composition ratios, on UCS, were analyzed using Exploratory Data Analysis (EDA) techniques, including histograms, box plots, and statistical modeling. The results show that the CBR increased from 10.43 to 22.94% for unsoaked and 4.68 to 12.46% for soaked conditions with 60% marble powder, ITS rose from 100 to 208 kN/m2 with 60–75% marble powder, and UCS rose from 170 to 661 kN/m2 after 28 days of curing, molding water content (optimum at 22.5%), and composition ratios (optimum at 60% marble powder). Complex modeling yielded R2 (0.954) and RMSE (29.82 kN/m2) between predicted and experimental values. This study demonstrates the potential of utilizing waste marble powder as a sustainable and cost-effective binder for soil stabilization, transforming weak soils into viable construction materials.

“…In the modification of clay soils, waste/residue materials and natural rocks or minerals are widely used today as additives, both because they can reduce environmental pollution by reducing carbon dioxide emissions, which is a global problem, during production, and because they are economical and environmentally friendly [2][3][4][5][6][7][8][9][10].…”

The strength properties of soils that are considered problematic, such as high plasticity clay, need to be improved for the increasing housing needs in parallel with the increasing population growth and the evolving needs of society due to continuous technological developments. In the last twenties, when global climate changes began to occur, improving the geotechnical properties of such soils, which form the basis of engineering structures, has become an important issue. For this reason, many studies have begun to improve and strengthen such soils using natural, synthetic, or various chemicals. For this reason, natural rocks are one step ahead of other healing materials in terms of being economical, sustainable, and environmentally friendly. In our study, Bayburt tuffite was added to the clayey soil by pulverizing it at the rates of 5%, 10%, and 15%, and the strength change after freezing and thawing was examined. Clay soil (CS) + Bayburt tuffite powder (BTP) mixture samples obtained in three different ratios were wrapped with stretch wrap in the laboratory environment (+20oC) and cured for 7, 14, and 28 days, ensuring the opt. moisture content was maintained. At the end of the curing period, the samples were subjected to +20oC, -20oC, 12 hours, and 10 cycles in the freeze-thaw cabinet, and then, Strength values were acquired with a uniaxial testing device. The highest strength value after freezing-thawing; was observed that it was 29.55% in the MIX1 (CS + 5% BTP) mixture cured for 28 days. As a result, it was concluded that this mixing ratio can be used in cold climates and shallow foundation depths with high plasticity clay soil properties.
