Briefing: Water content determinations of peaty soils using the oven-drying method
(2022)In order to prevent possible charring, oxidation and (or) vaporisation of substances other than pore water, many researchers have adopted oven-drying temperature (t) values in the range 60–90°C for water content determinations ... -
Cyclic swell–shrink behaviour of an expansive soil treated with a sulfonated oil
(2022)The effects of a sulfonated oil (SO) stabiliser on the swell–shrink properties of an expansive soil were investigated through cyclic wetting–drying tests. The cyclic wetting–drying action led to the reconstruction of the ... -
Effect of decomposition on physical properties of fibrous peat
(2014)Organic matter in peat deposits undergoes slow microbial decomposition, which causes permanent material change, including reduction in volume of solids, and is a significant factor in the development of creep settlements ... -
Effectiveness of granular columns in containing settlement
(2014)Laboratory-based research studies and full-scale evaluations of the behaviour of ground improved with granular columns are ample regarding bearing capacity, but limited in respect to the settlement response. This paper ... -
Fallacy of wide undrained strength range at the Casagrande liquid limit
(2019)The liquid limit (LL), as originally proposed by Atterberg, is notionally the water content below which fine-grained soil ceases to flow as a liquid. In many countries, the Casagrande-cup approach is the standard procedure ... -
Improving internal erosion resistance of silty sand using additives
(2020)Seepage-induced erosion, leading to piping, is one of the most common causes of failure for earth dykes, levees and dams. Various soil improvement (mixing) technologies can be employed to improve the internal erosion ... -
Reappraisal of soil extrusion for geomechanical characterisation
(2019)Reverse extrusion has been promoted over the past four decades for remoulded undrained shear strength (s u) measurement and consistency-limit determinations. The technique employs a uniaxial-compression test machine to set ...
