“…High improvement can be seen for soil strength with the content of the stabilizer. Amadi [20], Jimoh et al [21] investigated the use of cement kiln dust (CKD) to enhance the durability of black cotton soil (BC soil) subgrade modified with quarry fines (QF). Specimens were prepared with BC soil mixed with a constant dosage of 10% QF and five levels of CKD proportions (0%, 4%, 8%, 12%, and 16% by dry weight of soil).…”

Most of the soils suffered from significant geotechnical problems dependent on factors like the type of soil, soil composition and mineralogy. Specifically, the problems related to mechanical and physical properties of soils. Several studies have been used to mitigate the adverse effects of soils through using either additive conventional materials such as cement, lime or these soils blending with produced material and chemical materials. This paper focuses on stabilizing or improving different soils using sustainable materials. These materials provided environmental and economic benefits while mitigating a health hazard, storage problems, and a potential pollution source. They can be classified according to these sources into four groups: industrial waste (by-products), agriculture waste, domestic waste and mineral waste. According to the results of this review, compaction characteristics, California bearing ratio and unconfined compressive strength have been studied and discussed in this paper.

“…Soil engineering properties can be improved by using CKD as a pozzolanic binder (Peethamparan and Olek 2008;Carlson et al 2011;Albusoda and Salem 2012;Nasr 2015;Al-Homidy et al 2017;Fakhraldin and Abdulabbas 2017;Mosa et al 2017;Amadi and Osu 2018;Elbaz et al 2019;Ahmad et al 2020). Free lime (CaO), a high alkali content and a high degree of fineness (of the CKD material) have all been shown in previous studies to make CKD a promising candidate additive for improving soil characteristics (Anwar Hossain 2011; Ahmari and Zhang 2013;Nasr 2015;Ismail and Belal 2016;Al-Homidy et al 2017;Cui et al 2018;Jimoh et al 2018;Adeyanju et al 2020;Adarmanabadi et al 2021). Furthermore, compared to cement, CKD has the potential to penetrate fine-grained soils more efficiently, since CKD suspensions have reduced initial viscosity, meaning that they should not require high-pressure injections.…”

Effects of cement kiln dust on physicochemical and geomechanical properties of loess soil, Semnan Province, Iran

For problematic soils, conventional (cement and lime) additives can provide the necessary improvements in geomechanical properties for various infrastructure constructions. However, these additives have a high environmental impact and they are not always cost-effective, such that potential alternative additives (e.g. obtained as industrial by-products) require investigation. This paper examines cement kiln dust (CKD), obtained as a by-product of cement clinker manufacturing, for improving the geomechanical properties of an Iranian loess soil (sandy silt). Compaction, unconfined compressive strength (UCS), direct shear (DS) strength and soaking durability tests were performed on the loess soil and its mixtures with 5-20% CKD, investigating the effect of curing period (of up to 28 days) on the mobilised strength. Observations from mineralogical and microstructural examinations are also presented in this paper. Compared to the unamended loess, the strength and elastic modulus substantially increased for increasing CKD content and curing period. Improved strength and durability (under soaking) of the soil-CKD mixtures is explained by particle aggregation (of the loess soil), inclusion of the fine CKD material and the action of calcium-derived gel (linking) products. Hence, as well as reducing the disposal problem (of the CKD by product) in the cement industry, the use of this material, as additive for soil stabilisation applications, would provide an effective and sustainable option for improving the geomechanical properties, as demonstrated for the investigated loess soil.

“…Soils stabilized by binders are better suitable for the construction of road pavement and as a support layer for basement foundations of associated road infrastructure (Chen, 1988;Etim et al, 2022;Noolu et al, 2022). There are many examples on soil stabilization with various stabilizing agents: cement (Peng and He, 2009; Lindh and Lemenkova, 2022a, 2021b;), lime (Chitragar et al, 2021;Obuzor et al, 2012), fly ash (Mishra, 2012;Chethan and Shankar, 2021), CKD (Sharo et al, 2021;Lindh and Lemenkova, 2021a;Jimoh et al, 2018), slag (Wang et al, 2020;Lindh and Lemenkova, 2022c;Pai et al, 2020). Binders improve physical and mechanical properties of soil: strength, stiffness, porosity, permeability and compactness, which is crucial for road construction.…”

Clay soils can cause significant distress in road construction due to their low strength. Stabilizing such soil improve with binder agents prior to the geotechnical works can significantly its performance and ensure safety and stability of roads while exploitation. This research envisaged the use of five different binders (lime, energy fly ash, bio fly ash, slag, cement) as an additive stabilizing agents to improve the strength parameters of soil as required in engineering industry standards. The variations of strength was assessed using measurements of P-wave velocity of the elastic waves propagating through soil specimens stabilized by different combination of binders. Measurements were performed on 28th day of soil treatment. The best effects of added binders were noted in the following combinations: cement / energy fly ash / bio fly ash (P-waves >3100 m/s), followed by combination lime / energy fly ash / GGBFS (P-waves >2800 m/s) and cement / lime / energy fly ash (P-waves >2700 m/s). Adding lime is effective due to its fixation and chemical bond with particles. The study contributes to the industrial tests on soil strength for constructing roadbed.
