“…Recently different modern technologies such as nanoparticles were used for stabilization of the soils [3]. Sakr et al [18] studied the geotechnical and mineralogical properties of a lime treated high organic soft clay soil and showed that with increasing the curing age and lime percent, unconfined compressive strength increases.…”

“…Butron et al (2009) studied the effect of silica nanoparticles in the range of 5-100 nm, consolidation tests, three-axis and compressive strength on clay and showed that the soil containing nanoparticles were formable in the early stages of formation and they subsequently turn into elastoplasticity. Abbasi et al (2018) investigated the effects of nanoparticles on the dispersion potential and resistance parameters of two types of clay soil with low plastic and high plastic. For this purpose, initially, identification tests were carried out on two types of clay soil and nanoparticles.…”

In recent years, nano technology has been significantly implemented in geotechnical engineering, especially for soil remediation. Using this technology has improved soil resistance parameters and led to the stabilization of many problematic soils. Clay soils, due to their nature, have a large dispersion on the surface of the earth. The widespread dispersion of these types of soils in the site of structures, describes the necessity of studying and investigating new methods of improving and amending the resistive properties of these soils. This research is a review of the use of nanotechnology for the improvement of soil resistive properties by geotechnical researchers.

“…The increase in the unconfined compressive strength can be interpreted as the nano-clay material acts as fastening agent that ties soil particles together and decreases dispersivity potential as it is described in the research by Abbasi et al (2018). However, at higher dosages, the hydrophilic nano-clay will be surrounded with higher amount of water that prevents the nano particles from functioning well, with an increased nano-clay, the mechanical properties decreased due to the agglomeration of excessive nano-clay as what is explained by Gabr et al (2013), and this explains the drawdown of the unconfined compressive strength value to about its initial value.…”

Methane and carbon dioxide are of major concern as greenhouse gases; the landfills have the problem of controlling these gases. Al Akaider in Jordan is the second biggest landfill suffers controlling gases as it lacks a cover design system. In this work, the main goal is to investigate the appropriateness of amended expansive clayey soil in Irbid as a cover barrier. The expansive soil is unwanted in construction projects, thus the modification of this expelled soil enables using it as a low cost landfill cover barrier. In this research, the effect of adding nano-clay material (Hydrophilic Nano Bentonite) on the geotechnical characteristics, hydraulic conductivity, and gas transport coefficients of the clayey soil are studied. The soil samples were obtained from Irbid city. Unconfined compressive strength and free swelling tests were performed on soil samples with different percentages of nano-clay added in the range (0.1% to 1.2%) by weight. The results indicated that the addition of nano-clay at low percentages increases the strength of expansive soil up to 315 kPa at 0.6% of nano-clay and the swelling potential decreased dramatically with the addition of nano-clay. The optimal percent of nano-clay was found to be 0.6%. The intrinsic permeability of the amended soil was 6.03×10–15 m2. The average values of fluid transport coefficients were determined at 25 °C. The hydraulic conductivity for water was about 6.5×10–10 m/s. Gas conductivity coefficients for CO2 and CH4 were 5×10–9 m/s and 2.5×10–9 m/s respectively. Gas diffusion coefficients for CO2 and CH4 were 3×10–6 m2/s and 4×10–6 m2/s respectively.
