“…The pore fluid viscosity changes the properties of minerals and pore fluid contacts, thereby facilitating the displacement of particles relative to each other and displaying reduction in strength. These findings are supported by the results that were reported by Ratnaweera and Meegoda (2006) and Cabalar andClayton (2010 and. Therefore, the main reason for the reduction of strength due to 10 and 15% glycerol is viscosity.…”

Impact of water and solution of glycerol on the treatment of sediment by cement An understanding of the behavior of sediment soils deposited in different chemical solutions is important as it affects their treatment and their application in field as construction material. In this paper the effect of glycerol solution on the behavior of a sediment of a clay soil and its treatment was investigated through a program of experimental tests. Laboratory tests were conducted to study settlement of the clay soil in water and in solutions of glycerol with different concentrations. Also, treatment of the sediments deposited in water and solutions of glycerol was investigated by adding 5, 8 and 10 % cement to these sediments. Atterberg limits, compaction and unconfined compression tests were conducted on treated and untreated sediments. Comparison of the results showed that the Atterberg limits and compaction characteristics of the sediments that were deposited in water and in different solutions of glycerol are not the same. The properties of the sediments that were formed in glycerol solution are a function of concentration of glycerol. The results also indicted that the cement is effective in treatment of sediments deposited in solutions of glycerol and for a given percent of cement and curing time, the degree of treatment is dependent on the percent of glycerol in the solution. Increasing the concentration of glycerol decreases the strength of the sediment with time. Based on SEM analysis, it was found that the fabric of the soil deposited in water is different from those of the soils deposited in solutions of glycerol. The soil fabric also affects the interaction between soil and cement.

“…Many researchers have studied AGF and its effects on soil properties and mechanical behavior of frozen soils [20][21][22][23][24][25][26][27][28][29]. However, compared with unfrozen soils a greater effort is required to study frozen soils [30][31][32][33]. A mine shaft project near Swansea in South Wales is the first recorded application of AGF in 1862 [7].…”

The mechanical properties of frozen ground are key parameters in design and implementation of artificial ground freezing (AGF) in underground projects. Soil samples were obtained from the urban underground railway project site in Tabriz, Iran. The specimens were classified as SP and CL according to the USCS. The specimens were remolded in accordance with the site conditions. Over 120 triaxial compression tests were conducted on the frozen samples at different temperatures, confining pressures and strain rates. The results show that the frozen SP and CL soils exhibit strain-softening and strain-hardening behaviour, respectively. In all cases, Young's modulus increases with decreasing temperature and increasing strain rate and confining pressure. Also, the shear strength increases with decreasing temperature and increasing strain rate. In all tests, the Young's modulus and shear strength of the SP soil are greater than the CL soil. Based on the results of this research, the application of artificial ground freezing was recommended for coarse-grained and non-cohesive soils like SP in the Tabriz underground railway project.

“…Moreover, high temperature has been reported to reduce the soil strength and enhance crack formation [21]. Cabalar found that higher temperature leads to a jump in pore water pressure [22]. We determined that the strength of the red clay and expansive soil decrease with increasing temperature (from −4 to 60 • C), and red clay, in particular, exhibits higher heat sensitivity [23].…”

Exposed coal measure soil (CMS) found in the mountains of Southern China is significantly affected by the seasonal climate, which makes this region prone to frequent shallow landslides. In this regard, very few studies have focused on the shear strength and microscopic characteristics of CMS subjected to dry–wet cycling and temperature. The aim of this study was to experimentally investigate the effects of dry–wet cycling and temperature on shear strength and microscopic parameters of CMS. We carried out an unconsolidated undrained triaxial test and scanning electron microscopy of CMS obtained from the K209 slope on the Chang-li highway. Our results indicated that the soil shear strength and microstructure parameters significantly decreased before three dry–wet cycles. Above 35 °C, the temperature affected mainly the mean fractal dimension. The soil cohesion was negatively correlated with the fractal dimension and positively correlated with the probability entropy. The surface-crack occurred once the stress value of high temperature was greater than 0.57 MPa. Strain-softening, swelling–shrinkage, low soil strength, and high soil temperature formed the main factors underlying rainfall-induced K209 shallow landslides.
