“…Mixing of soil with 5-30% of cement kiln dust results in reduction of maximum dry density, liquid limit, plasticity and compressibility and increase in plactic limit, optimum water content and compressive strength and those trends are stable with increasing amount of cement kiln dust [15]. As mentioned in [16] the unconfined compressive strength of soil treated with cement kiln dust depends on the content of free lime and alkali (Na 2 O and K 2 O). The high amount of alkali contributes to deterioration of strength, while the increased content of free lime causes soil strengthening.…”

This paper presents the results of unconfined compressive strength tests carried out on samples of two different fine grained soils mixed with anthropogenic materials produced in Poland, showing binding properties – cement kiln dust and fly ash obtained from combustion of brown coal in a pulverized boiler. The tests were performed on cylindrical samples in a testing machine for compression tests after various curing time ranging from 1 to 8 weeks. The conducted work constitutes the first stage of research devoted to the recognition of the effects of calcareous fly ash and cement kiln dust addition into the fine grained soils.

“…It is clear there have been always to incorporate alternative material to make the soil stable specifically for clay material. Lime Kiln Dust (LKD) is one of the by-product [11,12,13]. Shortterm effect of LKD on strength of soil mix was done by [11].…”

“…Shortterm effect of LKD on strength of soil mix was done by [11]. Application of LKD in subgrade materials also studied by [13]. The above artciles shows the importance of further study due to environmental issues associate with landfill spaces and perhaps some contamination issue due to its reaction with climate conditions.…”

Soil stabilsation is one of the area which needs further research due to its importance both geotechnical and environmentally. Application of landfill materials and turn them into something worthwhile has been in attention of researchers. Lime Kiln Dust (LKD) is one of the materials which shows a potential of usage into soils. On other hand, Unconfined Compressive Strength (UCS) is also one of important tests in soil mechanics to represent characteristic of soil. Surely, in order to run UCS testing, compaction tests was conducted. The compaction values then utilized in the preparation of UCS samples. This study considers the effect of lime kiln dust on the UCS behavior of kaolinite-slag mixture. Compaction and UCS testing were conducted. The results showed that OMC was increased with increasing LKD in kaolinite-slag mixture and MDD was decreased with increasing in kiln dust. UCS also found to be with increasing in kiln dust. The results was support with different curing time (i.e. 7, 28, 90).

“…Accordingly, sewage can be a suitable replacement for cement or any expensive chemical stabilizer [6]. Soil stabilization has been carried out by the addition of different materials, such as Bagasse ash [7][8][9][10][11], rice husk ash [12], lime [13], fly ash [14,15], fuel oil fly ash [16], cement [17], coal ash [18], granulated blast furnace slag [19][20][21][22], and cement kiln dust [23][24][25]. Previously, the effective impact of potassium alum was observed on monazite in contrast with bastnaesite during flotation separation because of the special adsorption of hydrolyzed aluminum species [26].…”

The process of soil stabilization is a fundamental requirement before road infrastructure development is possible. Different binding materials have been used worldwide as soil stabilizers. In this study, water treatment waste (i.e., alum sludge (AS)) was used as a soil stabilizer. Alum sludge can work not only as a low-cost soil stabilizer but also can solve the problem of waste management at a large scale. Utilization of alum waste can be a sustainable solution and environmentally friendly exercise. Thus, in consideration of the pozzolanic properties of alum, it was applied as a binder, similar to cement or lime, to stabilize the soil with the addition of 2%, 4%, 6%, 8%, and 10% of dry soil by weight. To analyze the resulting improvement in soil strength, the California Bearing Ratio (CBR) test was conducted in addition to three other tests (i.e., particle size analysis, Atterberg’s limits test, and modified proctor test). The soil bearing ratio was significantly improved from 6.53% to 16.86% at the optimum level of an 8% addition of alum sludge. Furthermore, the artificial neural networks (ANNs) technique was applied to study the correlations between the CBR and the physical properties of soil, which showed that, at 8% optimum alum sludge, maximum dry density, optimum moisture content, and plasticity index were also at maximum levels. This study will help in providing an eco-friendly soil stabilization process as well as a waste management solution.
