Controlling role of suction stress in the Atterberg limits
… as those associated with plastic and liquid limit determinations. However, disregarding these concepts is tantamount to overlooking the fundamental role of water in soil behavior. Suction stress governs the Atterberg limits, and variations in suction stress behavior dictate transitions …

Effects of Temperature on Residual Shear Strength of Cohesive Soils
… of (1) the temperature effects on the liquid limit of cohesive soils, (2) the impact of testing procedure on temperature-dependent residual friction angle, and (3) temperature effects on residual friction angle of soils. The fall cone tests are used to determine temperature effects on …

Stratigraphy of offshore sediment of Lake Agassiz, North Dakota
… water content (17% to 56%), wide range of liquid limit (27% to 92%), and wide range of consistency index (22% to 86%). The northern part of the Brenna Formation has high water content (62% to 88%), a high liquid limit (63% to 104%), and very low penetration resistance (4 to 7 blows per …

An experimental study on time-dependent behaviour of reconstituted clayey soils in 1D and triaxial compression
… particle, coarse particle type, clay type, and liquid limit affect the secondary compression behaviour of oils. Results of constant rate of strain tests in oedometer and triaxial conditions show that at a given strain level, faster strain rates always result in a higher effective vertical stress …

Chemical, physical and mineralogical properties associated with the hardening of some South African fly ashes
… workings is highly sought after, as it may limit many of the impacts which fly ash induces on the environment. The main purpose of this study was to assess the degree of hardening of four South African fly ashes from power stations at Kriel, Lethabo, Matla and Sasol in terms of their …

The influence of salinity on the mechanical behavior of high plasticity soils
… soils from the Gulf of Mexico region, ranging in liquid limit from 62 % to 90 %, were tested to determine the impact of varying salinity on one dimensional consolidation and permeability properties. The majority of testing was carried out on Gulf of Mexico - Eugene Island (GOM EI). This material …

The meaning and practical significance of the cohesion intercept in soil mechanics
… soils, have a range of water content of 7-330%, liquid limit of 15-420%, plasticity index of 3-285%, liquidity index of $-$5.5 to 3.5, sensitivity up to 500, clay fraction of 2-93% and, activity of 0.1-9.6. The preconsolidation pressure ranges from a low of 44 kPa to a high of 14000 kPa. The …

Ground improvement using PET bottle waste as a potential reinforcement material for granular columns: an experimental approach
… bed (prepared at optimum moisture content or liquid limit) was created within a steel cylindrical tank. An ordinary granular column (OGC) or reinforced granular column (RGC) was then installed within the tank and a compressive vertical load was applied to the prepared sample up to a settlement …

Drained shear strength of stiff clays for slope stability analyses
… and fully softened research have a range of liquid limit of 24 to 286%, plasticity index of 8 to 244%, and clay-size fraction of 10 to 88%.

Soil compaction of peat under the influence of electrokinetic stabilization (EKS) treatment
… strength, compressibility, permeability and liquid limit). Peat is considered as one of the problematic soil in construction projects all over the world, which covers about 4% land of the whole world while 8% of the total area of Malaysia and about (5.86%) of peat soil existing in Johor …

Potassium acetate treatment as a potential means for stabilising extra sensitive, halloysite-rich soils in the Bay of Plenty, New Zealand — A novel approach to an old issue
… could be regarded as strengthened. Atterberg limit testing of the soil showed the untreated Pahoia Tephra to have a liquid limit higher than the natural moisture content (61%), meeting the requirements for an extra-sensitive soil, as was determined by field shear vane tests. Treatment with the …

Development of instrumented oedometer incorporated with bender element and electrical conductivity
… agent. All specimens were mixed at twice the liquid limit. Prior to testing, all solidified specimens were cured for 7 days. It was found that Vs increased continuously with further curing time whereas EC increased during the first day and decreased with further curing. The compressibility was …

Effects of Mica On Soil Properties For Embankment Construction
… specific gravity, particle size distribution, liquid limit, plastic limit, and soil classification. Tests for mechanical properties include standard Proctor compaction, direct shear, and triaxial compression. Tests for chemical properties include soil pH, soil resistivity, chloride content and …

Foundation Design of Low Volume Roads: Evaluation and Performance
… laboratory testing included moisture content, liquid limit, plastic limit, and gradation tests. The results of the tests were used to compare the layer thicknesses and material properties to both the performance of the roads and the suggested thicknesses and material specifications from the …

The effect of certain sludge floc properties on the dewatering characteristics of biological and chemical waste sludges
… through the use of the standard Atterburg liquid limit test procedure. Finally, the use of high-pressure filtration was found to provide much more appropriate information regarding water content than the centrifugation method proposed by Vesilind (1979).

Soil and Site Characterization Using Electromagnetic Waves
Success in geotechnical analysis, design, and construction invariably requires that we have proper knowledge and understanding of (1) the strength, (2) the fluid flow properties, and (3) the stress-deformation behavior of the earth materials. These important engineering properties are primarily …

Stiffness characterization of mechanically-compressed cohesive soils using wave propagation
… to the soft clay. Unfortunately, the stress limitation of bender elements precludes it from testing above 1.5 MPa. A novel setup using ultrasonic transducers, with electronic conditioning, is developed in order to overcome the difficulties of transmitting a shear wave through a soft material. …
