“…These results are different from the work in [46] and it was attributed to effect of temperature on permeability. Result from this study matches very well with the work in [62] for local Indian clay.…”

“…Small decrease in m v by increase in temperature is also reported in [46]. Bag and Rabani [62] studied the effect of temperature increase on consolidation and swelling pressure for commercial bentonite and local soil from India which are classified as CH and CL, respectively, using modified oedometer device. It was observed that for bentonite, m v is decreasing with increase in pressure and the effect of temperature is negligible.…”

Temperature change in soils and its possible effects date back to 20th century where temperature difference between laboratory and field for sampling made researchers interested in this topic. Due to development of technology and industry nowadays, new engineering applications such as nuclear waste disposal, oil extraction and pipelines, geothermal structures etc. have turned temperature change in soils to one of the high trending research topics where suitable knowledge of thermal effects on soils is required. For this purpose, it is tried at first to highlight the importance of temperature effect on geotechnical design by some examples and possible effect of temperature change on mechanical properties of fine soils are reviewed afterward. Investigation on results from literature proved that temperature change could alter some strength and consolidation parameters of fine soils. Different factors are proposed to be responsible for such thermally induced changes in mechanical parameters, however, existing explanations and comments from literature are diverse and not fully understood yet. In order to fill this gap, it is tried to find connections between different mechanical parameters and their behavior toward temperature change and possibly find a unified approach and factor to explain the mechanism responsible for thermally induced changes in mechanical parameters of fine soils. Finally, at the end, it is concluded that effect of temperature on structural rearrangement of solid particles could be a promising factor to connect the responses of different mechanical parameters toward temperature change.

“…It was observed that compression index and overconsolidation ratio of sand samples were independent of temperature [5]. In another study, it was shown that the compression index (Cc) of bentonite increased with increasing temperature [6]. According to results of this study, the volumetric compression coefficient (mv) decrease with increasing consolidation pressure but it was not affected by temperature.…”

The importance of thermal behaviour of soils has increased significantly with increasing number of energy structures. There is a need for soils, which show design criteria (strength, permeability, etc.) performance during their life under high temperature or thermal cycles. In the literature studies, it was observed that the volumetric deformation of the soil changes with increasing temperature. Sand-bentonite mixtures generally act as impervious barrier in areas such as nuclear waste repositories, landfill liners etc. These mixtures will be exposed to high temperature; therefore, their engineering performance should not alter under high temperature. Boron is used in the industry for high temperature resistance, flexibility, lightness, power and ease of production. Boron minerals have very low thermal expansion and they are also resistant to thermal shocks. For that reason, the properties of sand-bentonite mixtures can be improved by boron additives at high temperatures. In this study, volume deformation behavior of sand-bentonite mixtures was determined in the presence of tincal. The oedometer tests were performed under room temperature and 80°C.

“…e swelling pressure of a material is a resistance to maintain its initial volume and shape [19]. Many researchers have studied the swelling pressure of soil and rock materials, proposing models to predict the swelling pressure and swelling potential based on swelling pressure tests [20][21][22]. However, the swelling pressure properties of sealing materials throughout the hydration process have rarely been examined in detail.…”

To improve coal seam gas drainage performance, we developed a double-expansive (DE) material to seal the borehole. The swelling process of this material includes an initial swelling stage and a secondary swelling stage. We studied the swelling pressure properties of the DE material under four constraint conditions using a self-made swelling test device. Further, the active support effect of the DE material on the borehole was analyzed by simulating borehole stability with COMSOL Multiphysics software. The results exhibit the following: (1) The swelling pressure of the DE material exhibits time-dependent behavior, and the mathematical relationship between the swelling pressure and time can be obtained by nonlinear fitting. (2) The radial swelling potential is principally formed during the secondary swelling stage, providing the main active support on the radial constraint. (3) The active support imposed on the hole wall can prevent the extension of plastic and damage regions around the borehole, for improved stability of the gas drainage borehole. Finally, field tests demonstrate improved gas drainage performance of the borehole sealed by the DE material compared to a conventional sealing material.
