Utilization of fly ash and lime to stabilize the expansive soil and to sustain pollution free environment – An experimental study

Electrocoagulation Technique for Cephalothin Sodium Removal with Effective Sludge Management

“…From the results, it can be seen that the natural water content decreased from 12.36 to 11.54 % by the addition of 0.2 % of EC sludge. This indicates that the moisture‐carrying capacity of the soil decreased, thereby favoring the possibility of using it for constructional purposes 21, 32. MC is the moisture content, W 1 is the weight of the container, W 2 is the weight of dry soil with container, and W 3 is the weight of wet soil with container, all in mg. …”

“…The EC sludge obtained after the treatment of antibiotic wastewater was used for soil stabiliza- tion. To find out the characteristics of the BC soil before and after the stabilization, geotechnical lab tests such as unconfined compression (UCC) test, compaction test, Atterberg limit test, specific gravity, and swelling index test were conducted and the results were compared [22,32,33]. The EC process leads to a minimum amount of sludge production, so the admixture composition of sludge added to the BC soil is fixed to 0.2 wt %.…”

“…This can be attributed to the chemical reactions between the soil and the additives which form cementitious materials which could reduce the volume of the voids and improve the compressive strength. Based on the UCC results it can be stated that the qualitative properties of the soil enhanced much and can be used for constructional purposes [21,32].…”

“…The LL changed from 46.5 % to 48.6 % and the same trend was obtained by Kumar and Kumar [20] in soil stabilization studies by electronic waste. The magnitude of the shear stress that a soil can sustain is increased, thus the intrinsic capacity to rest the failure when forces act on the soil is also higher [32,34].…”

Utilization of Fluidized Bed Combustion Fly Ash in the Design of Reuse Clay Soil in the Form of Self-Compacting Grouts

“…In this paper, the method of improving the properties of clay soils focused on is chemical stabilization by FBCA and their subsequent liquefaction.Chemical stabilization aims to modify the soil moisture and, above all, to improve its strength, which increases the soil's softening resistance [12][13][14][15][16][17]. The amount and type of FBCA added should in fact be consistent with the clay mineral content of the soil [11,[18][19][20][21][22]. Exact values of the amount and determination of the effect of FBCA on clay soil can be determined after the implementation of laboratory tests.Non-traditional possibilities of clay soil treatment include liquefaction into a self-compacting grout [23][24][25].…”
