Consolidation Characteristics of Soils Stabilized with Lime, Coal Combustion Product, and Plastic Waste

Use of quick and hydrated lime in stabilization of lateritic soil: comparative analysis of laboratory data

“…On the whole, increased lime content resulted in increased plasticity reduction. Similar results have been reported by Dash and Hussain [10], Okoro et al [21] and Cherian and Arnepalli [6]. As a result, there can be an immediate change in the workability of the material caused in the first instance by cation exchange which occurs when calcium ions released by the lime, exchange with metal ions within or on the clay structure.…”

“…In addition, the higher pH environment in the treated soil changed the surface charge distribution in the clay soil particles, resulting in an increase in repulsion between particle layers. This, along with changes in the particle size distribution, caused a decrease in maximum dry unit weight [21,23]. The increases in OMC with increasing lime content may be due to increase of fine fraction and the hydration of lime [10,15].…”

Strength and compressibility characteristics of soil stabilized with plastic bag strips

“…Irrespective of χ, C c and C r decrease with an increase in t. It is evident from the test results that PBS has the potential in controlling the swelling behavior of soil. The variation in C c and C r with χ is consistent with the observation made byOkoro et al (2011).…”

“…The increase in the amount of plastic waste in the range of 0.4-0.8% improved the shear strength, compressive strength, and the CBR values of lime stabilized soft soils. Okoro et al (2011) added fused plastic bottles to clay to improve the consolidation characteristics of the soil. Plastic bottles heated at 275 0 C were mixed with the soil (plastic to soil ratio of 1) and it was found that the plastic waste stabilized specimen exhibited a lower initial void ratio.…”

Geogrid in paved and unpaved road systems: A review of mechanisms and design mehods

“…For that, waste material can be employed to increase the efficiency of lime or cement. Many researchers (Eberemu, 2011;Mir and Sridharan, 2014;Nalbantoglu and Tuncer, 2001;Okoro et al, 2011;Sureban, 2011) have discussed that the benefits of using waste materials. Phanikumar and Sharma (2007) showed that the reduction in swelling might basically be at-Swelling pressure and consolidation of soft clay stabilized with bagasse ash and lime Hayder Hasan, Liet Dang, Hadi Khabbaz & Behzad Fatahi…”
