“…LL, PL and PI values have increased in K soil. The increase in soil atterberg limits can be caused by chemical interaction between soil particles and wastewater [11]. The related literature studies show that the atterberg limits of soils increase or decrease due to the effect of pollutants [20 and 22].…”

“…Reduction of strength due to contamination may result from weakening of bonds between soil particles [13]. The possible decomposition of mineral particles in soil is also cited as a cause leading to decrease in soil strength [11]. The decrease in strength and strain depending on the nature of contamination can be attributed to the interaction of pore water viscosity and mineral particles [19].…”

“…The decrease in strength and strain depending on the nature of contamination can be attributed to the interaction of pore water viscosity and mineral particles [19]. A study about soils contaminated with wastewater concluded that the unconfined compressive strength of soils can decrease up to 60% over time [11].…”

In recent centuries, issues such as efficient use of water resources, water quality and water supply have become important for many countries. Countries have focused on developing strategies that can protect water and using water in the most efficient way including treatment of wastewater. In addition, it has become important to provide sustainability of the natural treatment systems instead of complex and expensive wastewater treatment facilities that are rapidly developing. On the other hand, the researches on natural treatment of wastewater are still inadequate. Therefore, the feasibility and performance of new stragtegies about natural treatment systems should be developed and evaluated. For this purpose, a pilot facility was developed which utilizes a natural soil-column with different gradations in order to provide the treatment of domestic wastewater. In this way, not only the wastewater treatment performances of different soils but also some engineering properties of soils affected by wastewater filtration were examined. As a result of this research, it was found that soil filtration can be effective in the treatment of wastewater subjected to pre-sedimentation and can be affected by the pollutant load of the filtration environment.

Evaluation of the Improvement Effect of Limestone Powder Waste in the Stabilization of Swelling Clayey Soil

et al. 2019

View full text Add to dashboard Cite

The natural stone industry generates large amounts of industrial waste every year. Limestone powder produced by the activity of this industry is dumped into landfills, generating an environmental impact that could be reduced by using this waste as a binder in building materials. In the present work, the use of this by-product as an addition for soil improvement of clayey soils has been studied. The tested natural soil is a soft clay from southeastern Spain, which has been mixed by adding 5, 10, 15, 20, and 25% of dry limestone dust by total dry weight of the soil. The natural soil and the additive have been characterized, in addition to the common geotechnical tests, by means of X-Ray diffraction and X-Ray Fluorescence. The improvement of the geotechnical properties of the mixed soil has been evaluated by means of the change in the Atterberg limits, free swell index, unconfined compressive strength, and one-dimensional consolidation test. The change in the microstructure of the mixed soil has been studied by scanning electron microscopy. In general, the results obtained show an increase in the strength of the soil and a reduction of its deformability when limestone powder is added.

“…The results show that the granulometric composition of the reclaimed soil changes dramatically with varying depths from 10 m-70 m. For a depth of 10 m, the granulometric composition is similar with that of undisturbed reclaimed soil; while when the depth is 70 m, the fine particle content is greatly different with that of undisturbed reclaimed soil. Stabilization Using Industrial By-Products [50].…”
