## 1 Introduction  
Industrial activities generate a large amount of waste that cannot be simply dumped into landfills due to its adverse environmental effects. Waste and industrial by-products must be managed to ensure sustainability and achieve the Sustainable Development Goals adopted by the United Nations. Soil stabilization is one of the potential uses of industrial waste. Soil stabilization is used to improve the geotechnical properties of natural soils when they do not have the acceptable strength or stiffness to be used for embankments or other earth fills. Lime and cement are the most common binders used in soil stabilization. Despite the great properties obtained in binder-treated soils, research on obtaining sustainable materials to be used for soil stabilization has increased significantly in recent years due to the adverse effects on the environment caused by the binder-making process, such as high CO\({}_{2}\) emissions and the use of vast amounts of raw material. For example, the use of ground granulated blast furnace slag has resulted in a reduction of the swelling potential [1] and an increase in the soil shear strength [1; 2; 3]. Fly ash has also been studied for soil stabilization with good results, reporting a decrease in plasticity and an increase in soil strength [4; 5; 6]. Other industrial by-products, such as waste glass, are also being investigated for soil improvement [7; 8]. These sustainable materials can be used as a partial replacement for traditional binders, especially inert by-products. For example, class C fly ash and lime are a good combination for stabilizing silty and sandy soils [9; 10]. [PERSON] et al. [11] found that the pozzolanic reaction of fly ash was minimal when mixing it with a blended cement-stabilized silty clay. Nevertheless, fly ash was shown to have a positive effect on soil stabilization. [PERSON] et al. [12] studied the effect of silica fume on the microstructure of a soft soil stabilized with cement. This research concluded that silica fume can reduce the voids in the mixed soil, increasing its strength. However, an excess in the silica fume content employed can result in the opposite effect. Recycled-glass powder was also studied as an additive to soil stabilization with lime [13]. The results obtained showed an improvement in the microstructure and the mechanical properties of the mixed soil when increasing the glass powder content. [PERSON] and [PERSON] [14] reviewed the utilization of some sustainable materials (fly ash, cement kiln dust, blast furnace slag, rice husk ash, silica fumes, red mud, and textile waste) for soil stabilization, concluding that there was a need for further research to make these materials a practical replacement of the commercial binders. Moreover, solid waste and limestone materials are widely immobilized in cement-based materials [15; 16]. Limestone powder is an industrial waste generated from cutting and polishing works by the natural stone industry. This industry is present in many countries worldwide. The global market for the natural stone industry was estimated to be 18 trillion metric tons in the year 2020 and is expected to be about 23 trillion metric tons by 2027 [17]. Due to the large amount of waste generated, efforts are being made to find a constructive use for this limestone powder, transforming the industrial waste into an industrial by-product. Figure 1 shows the temporary landfill for limestone powder waste of a single company in southeastern Spain. Some promising results have been reported when studying natural stone industry waste, which is mainly composed of calcium carbonate, in soil stabilization. Amongst these positive results, a reduction in the Atterberg limits [18; 19; 20; 21], a reduction in the free swell index [20; 21; 22; 23; 24], and an increase in the strength of mixed soil [20; 21; 22; 25] can be highlighted. Studies about using this industrial by-product as a ternary element, combined with lime or cement, in soil stabilization are very limited. The results reported by [PERSON] et al.
