Soils with high plasticity tend to have strong plastic properties and easily deform when exposed to shear forces. These soils are often a problem in construction because of their ability to cause deformation and cracks in structures. Therefore, high plasticity soils require stabilization to increase their bearing capacity and reduce the risk of damage to the structure. A sample of this soil-stabilizing is marble dust waste which is normally generated in large quantities and has been discovered to hurt the environment. Therefore, this study focuses on determining the effect of marble dust waste addition as a stabilizer on soil's physical and mechanical properties. The physical properties tests carried out were the physical properties tests for compaction, Atterberg limit, specific gravity and particle size distribution of the original soil, the mixed soil, and the marble powder's chemical properties. The chemical properties test of marble powder consists of XRF and SEM-EDX tests. Based on the characterization results, marble powder is dominated by CaO compounds, the morphology of the particles is agglomerated and irregular shape. The mechanical test conducted was a CBR with the marble powder waste varied at 0%, 7% and 27% for a curing time of 0, 3 and 7 days. The results showed that adding the material reduced the plasticity index (PI) value from 29.24% to 10.56% and increased the CBR value by 15.50% by applying a 7% variation over a 7-day cure time. Additionally, it's important to note that the CBR standard for subgrade specifications typically requires a value exceeding 6%. This indicates that the curing time affects the increment in the CBR value and that marble powder wastes can be used as an additive for sustainable soil stabilization.

“…A number of these materials are unavailable in some regions, while others are impractical for local-building reasons [19][20]. The potency of recycling and/or reusing byproduct waste in engineering construction has recently attracted the attention of many researchers; doing so would reduce the environmental issues related to waste disposal and the costs of materials [21][22][23][24][25][26][27][28][29]. There is a kind of industrial waste called cement kiln dust (CKD), created when exhaust gases from a cement kiln.…”

Dune sands occupy large parts of Iraq, posing significant challenges for infrastructure building. Geotechnical research and stabilization for dune soils are necessary to determine the engineering features of these soils as a foundation material in consideration of the global growth in construction activities, especially in Iraq. The compressibility and collapsibility of dune soils are key soil features in the design and construction works, which must be carefully analyzed. In this study, selected geotechnical properties, including compaction, compressibility, and collapsibility characteristics, of compacted dune soil samples from the city of Tikrit were evaluated in the laboratory using a specific range of “cement kiln dust (CKD)” concentrations as a stabilizing agent. The amounts of CKD used in this study were 4, 8, 12, 16, and 20% by dry weight of dune soil. The results showed that adding CKD to Tikrit dune soil improved the compaction properties, decreased the compressibility, and amazingly eliminated the collapsibility. The quality of Tikrit dune soils treated with CKD is very high, and it is recommended for use in the construction of geotechnical engineering works.

“…The use of by-product materials in stabilization clay soils has different economic, environmental, and geotechnical benefits. Among these materials is silica fume, this material is produced by smoke condensation in the production processes of ferrosilicon metal [11][12][13]. The effect of silica fume on soil properties is reviewed in the literature.…”

Engineering structures found in, or on, some clay soil types may be subject to different damages due to the problematic nature and unfavorited properties of these soils. The unfavorited properties of these soils include shrink and swell changes, high settlement, and low bearing capacity. These soils have high sensitivity to moisture change. The way to reduce or overcome the unfavorited properties of problematic soils is the treatment or enhancement of these soils using different mechanical or chemical methods. In the present paper, silica fume selected as a soil stabilizer material, the effect of different contents of this material on the geotechnical properties of expansive clay soil has been experimentally investigated. Tests included soil specific gravity, soil plasticity, soil compaction, and soil compressibility. It was noted that silica fume, with different contents, decreased the specific gravity, and compaction density, while the compaction water content and Atterberg limits increased. The consolidation parameters of the expansive clay soil were affected by adding the silica fume. The silica fume reduced the consolidation parameters values of the clay soil. At low content silica fume, less than 10%, a very slight reduction can be seen especially for the rebound index value. The final findings of this paper appeared that the high settlement of clay soil can be reduced with the presence of silica fume.
