Calcium-based stabilizer materials (CSMs) exhibit pozzolanic properties which improve the properties of clayey soils by hydration, cation exchange, flocculation, pozzolanic reaction, and carbonation. In this comprehensive review, comprising over past three decades from 1990 to 2019, a mechanistic literature of expansive soil stabilization by incorporating CSMs is presented by reviewing 183 published research articles. The advantages and disadvantages of CSMs as the ground stabilizing agent are succinctly presented, and the major outcomes of physicochemical effects on soil properties are discussed in detail. After blending with CSM, the main and interaction effects on soil properties with focus on chemical processes such as X-ray fluorescence, X-ray diffraction analyses, and microstructure interaction by using scanning electron microscopy and thermogravimetric analysis have been reviewed in light of findings of past researchers. This work will help geotechnical engineers to opt for suitable CSM in the field of geoenvironmental engineering in committing to sustainable construction of civil engineering structures over expansive soils.

“…Similar to the performance of lime in stabilizing dispersive soils [ 29 , 30 , 31 ], the cation exchange, flocculation and agglomeration, and pozzolanic reaction can occur as a clayey soil reacts with certain free oxides in SFS. Various research studies have been conducted to employ SFS to enhance the properties of problematic soils, while primarily demonstrating that SFS can be an effective stabilization agent [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ]. From the early 1990s, Akinmusuru [ 43 ] pioneered the attempt to use SFS in soil stabilization for rural roads with low traffic volume, which suggests that SFS possesses the potential to improve the soil properties by increasing the strength, California bearing ratio (CBR), and dry density.…”

“…A recent study of Akinwumi [ 42 ] concluded that the addition of SFS to lateritic soil increased the dry density, decreased the optimum moisture content, and, as the percent SFS increased, the soaked and un-soaked CBR and the unconfined compressive strength increased. Zumrawi and Babikir [ 47 ] studied the effectiveness of adding 5%, 10%, 15%, 20%, and 30% of SFS to an expansive soil and reported that the addition of SFS improved soil properties. Abdi [ 49 ] investigated stabilizing a kaolinite soil with a combination of BOF slag and hydrated lime, which demonstrated that higher BOF slag with lime contents yielded higher compressive strengths.…”

The research study described in this paper investigated the potential to use steel furnace slag (SFS) as a stabilizing additive for clayey soils. Even though SFS has limited applications in civil engineering infrastructure due to the formation of deleterious expansion in the presence of water, the free CaO and free MgO contents allow for the SFS to be a potentially suitable candidate for clayey soil stabilization and improvement. In this investigation, a kaolinite clay was stabilized with 10% and 15% ladle metallurgy furnace (LMF) slag fines by weight. This experimental study also included testing of the SFS mixtures with the activator calcium chloride (CaCl2), which was hypothesized to accelerate the hydration of the dicalcium silicate phase in the SFS, but the results show that the addition of CaCl2 was not found to be effective. Relative to the unmodified clay, the unconfined compressive strength increased by 67% and 91% when 10% and 15% LMF slag were utilized, respectively. Likewise, the dynamic modulus increased by 212% and 221% by adding 10% and 15% LMF slag, respectively. Specifically, the LMF slag fines are posited to primarily contribute to a mechanical rather than chemical stabilization mechanism. Overall, these findings suggest the effective utilization of SFS as a soil stabilization admixture to overcome problems associated with dispersive soils, but further research is required.

“…[20] stated that the addition of eggshell powder to the expansive soil increased from 5 % to 20 %. After adding eggshell powder, linear shrinkage decreased by 10 % after 28 days, the maximum dry density of the expansive soil decreased from 1.323 g/cm 3 to 1.293 g/cm 3 . In addition, there was an increase in geotechnical characteristics after adding 5 % eggshell powder, compressive strength at collapse and strain increased by 18 % and 9 %, compared to expansive soil without treatment.…”

Expansive clay is one of the problems in construction work. The soil has the characteristics of being easy to expand when exposed to water, causing a decrease in the strength value of the soil. The can be overcome by stabilizing the soil. The soil is formed from weathering and contains the mineral montmorillonite. The soil is very sensitive to moisture content, has a high shrinkage rate, thus interfering in construction work. Therefore, additional materials are needed to overcome the problem, one of which is soil stabilization. The study aimed to stabilize the expansive clay soil. This is done by analyzing the physical and mechanical properties of expansive clay with a shell ash mixture. Expansive clay is taken directly (undisturbed) or disturbed. Undisturbed soil is taken using a tube, so that the soil is not disturbed by outside air, while disturbed soil is taken using a shovel and then put into a sack container. Expansive clay stabilization method lies in adding the percentage of shell ash mixture (5 %, 10 %, 15 %, and 20 %). The soil, the initial moisture content (γd) of which has been determined, is mixed, then molded into a cylindrical shape. The mold was stored in a desiccator, then watered with 5 % water every day until the soil became saturated. Then, using a Proctor test, chemical tests (soil chemical test, soil mineral test), physical tests (soil moisture, Atterberg limit), and mechanical tests (unconfined compression test, compaction test, swelling test) were carried out. The results showed that the addition of an oyster shell ash stabilizing agent to expansive clay affected the physical and mechanical properties of the soil. The addition of shell ash can reduce soil moisture with various plasticity indexes. While the soil stress value decreased, the swelling of the soil increased significantly above the original soil.
