Abstract. The water retention behaviour of partially saturated MX-80 bentonite with pure water is relatively well investigated. However, in practical cases, the water contains a number of chemical compounds which affects the bentonite behaviour. In particular, bentonite is used in buffer applications of geological repositories for spent nuclear fuel, where the concentration of total dissolved solids in groundwater is expected to increase significantly with time. This paper investigates water retention behaviour of MX-80 type bentonite partially saturated with deionised water as well as 1M NaCl solution. In the experiments the specific volume of bentonite has been kept approximately constant.

“…The limitation of the present pressure plate device used here was that it can only measure matric suctions up to 1,000 kPa. Hence, for high suction ranges, the filter paper method was followed, as this method can provide suctions larger than 1,000 kPa (Bulut et al 2001). Overall, both pressure plate and filter paper test methods were utilized in the development of complete SWCC profiles of the test soils.…”

“…The water content of the filter paper was later measured after the test reached equilibrium condition after undergoing the vapor transmittal for a period of ten days. The suction was estimated from the moisture content of the filter paper using a calibration curve established by Bulut et al (2001). By measuring the soil suctions at various compaction moisture content conditions, the soil-water characteristic curves were then drawn from low to high suction conditions.…”

Expansive soils have long been recognized as problematic because they cause failure to civil structures constructed above them. The main problem of these soils can be attributed to poor understanding of the volume changes caused by moisture fluctuations. Current swell and shrinkage characterization models are limited by both the lack of standardized tests and tests that employ volume changes in uniaxial direction. In the present research, a comprehensive laboratory investigation was undertaken to study the volume change related swell-shrinkage behaviors of five different types of expansive clayey soils sampled from various regions in Texas, USA. Extensive experimental programs consisting of basic, chemical and mineralogical soil properties were first determined. Three-dimensional free swell and shrinkage tests were performed on all soils at various compaction moisture content conditions. Soil water characteristic curves (SWCCs) of all test soils were determined by studying the suction potentials of these soils over a wide range of moisture contents. Volume change measurements of soils showed a good correlation with soil properties, including plasticity and soil compaction properties. SWCC results also showed a clear variation in SWCC profiles of soils with respect to soil plasticity. Overall, a large database of soil properties was developed and is presented here. It includes physical and mineralogical properties, and engineering test results including swell, shrinkage and SWCCs. This is an author-produced, peer-reviewed version of this article.
