...Bahador Yazdanpour; Mehran Karimpour-Fard; Mohsen Sabermahani; Sandro Lemos Machado ABSTRACT The mechanical response of municipal solid waste (MSW) under different types of loading and testing conditions has been explored by many researchers. However, the effect of temperature on MSW...

..., a modified thermomechanical triaxial cell that can control the specimen temperature at a specified rate is utilized. Unlike other thermomechanical systems, a separate backpressure pump is connected to each drainage line (top and bottom) measuring the thermally-induced volumetric strains of water filling...

... to other techniques, synchrotron diffraction provides (1) high accuracy and sensitivity to small changes compared to benchtop XRD and (2) the ability to assess microstructure changes under in situ conditions (i.e., stress, saturation, and temperature). The design and selection of the various materials used...

The article concludes that the proposed narrow wall system works effectively and has been able to capture the temperature stress–strain behavior of paste backfill. Thus, the temperature effect hypothesis has now...

...-isothermal and unsaturated conditions. The advanced oedometer cell enables the simultaneous control of temperature, suction, and stress state within the soil specimens. Temperatures of 20°C to 200°C are applied through a tubular heating element placed at the base of the soil specimen. Suction is controlled...

... technique to account for use of PES membranes and effects of different PEG molecular weights, concentrations and temperature. This study intends to fill such a gap by providing reliable and comprehensive experimental data. The response of PES membranes was investigated over a range of temperature varying...

...A. Sadrekarimi Triaxial shear tests are often carried out in a temperature controlled laboratory environment, and a few degrees change in ambient temperature are often neglected or considered to have negligible effect on the experiment. In this study, the effect of the ambient temperature...

...Rune Dyvik Triaxial tests on soils typically have a latex membrane that confines the test specimen. Because temperature can affect geotechnical test results, laboratory testing is occasionally performed at in situ temperatures, which are typically lower than room temperature. Some long-duration low...

...Anuchit Uchaipichat; Nasser Khalili; Saman Zargarbashi This paper describes a modified Bishop–Wesley triaxial apparatus for testing unsaturated soils at elevated temperatures. The suction is applied using the axis translation technique. The cell liquid temperature is controlled through a heating...

...Tom Schanz; Wiebke Baille; Long Nguyen Tuan This paper analyses the effects of temperature on the quantification of soil water content by means of time domain reflectometry (TDR) method. For this purpose, the dielectric constant of soil specimens with known water content was measured at different...

...Bertrand François; Lyesse Laloui This paper reports the development of an advanced thermo-hydro-mechanical (THM) oedometer in order to characterize the behavior of soils under combined non-isothermal and unsaturated conditions. The simultaneous control of temperature, suction, and stress states...

...K Farrag A procedure for extrapolating creep strains to longer time intervals was developed. The procedure was based on applying time-shift factors to creep strain curves at elevated temperatures to establish a master strain curve for longer time intervals. The procedure was applied to creep test...

...K Farrag; H Shirazi The prediction of the long-term strength of geosynthetics is usually based on 10,000-h extension creep tests. Creep tests at elevated temperatures can accelerate testing duration to a reasonable time frame (1000 h) and the results can be extrapolated to longer time intervals...

However, control of temperature gradient, existence of one-dimensional flow, and uniformity of temperature and volumetric water content distributions at any cross section within the specimen are achieved in the modified design. Experimental results have shown that the temperature stabilizes very...
