1.Overconsolidation properties,lowdegree of density,and characteristics of deformation of red clay are discussed herein based on the data of field investigations and indoor test.根据野外现场调查和室内的实验资料,对红粘土的超固结性及低密实度和变形特征进行讨论,指出红粘土是超固结土,但同时密实度很低。

The relationships between some soil physical and chemical properties such as, clay content (C), silt content (Si), sand content (S), ...
The bulk density (2650 kg/m3) and bulk modulus (36–40 GPa) of quartz are the most common values used in geoacoustic modeling [61]. Other common sediments include carbonates (bulk density, 2710 kg/m3 and bulk modulus, 64–75 GPa), and clay minerals (bulk density, 2600–3000 kg/m3 ...
Infiltration measurements were made on swelling clay soil samples packed into columns. Small increases in bulk density over the range 1.10 to 1.25 g/cm3 markedly decreased the rate of water movement. The magnitude of the effect was greater for confined samples than unconfined samples at all initial...
Changes in the site density and surface acidity constants (i.e. pKaand pKa) of kaolinite and montmorillonite were determined after acid or alkali spills, and pH buffering capacity was evaluated as a parameter of soil function change. Surface complexation modeling with potentiometric titrations and ...
clay-richglacial till. It generally doesn't work for gravel, dry sand and silt, or anything cemented. The preferred device is a section of aluminum pipe several inches long. It's helpful if the edges of the ends of the pipe have been beveled on the outside to make a sharp edge. The...
Soil bulk densities were measured with respect to depth in a clay loam and sandy soil. Coefficients of variation for the clay loam and sand plot areas (400m2) ranged from 39 to 15.0% and from 2.3 to 10.7%, respectively. Each of 8 sampling sites on the clay loam soil displayed distinct...

We validated the method through comparison to the standard displacement method, and then used the method to create a soil shrinkage curve for the Waldo silty clay loam soil. The method had acceptable precision (relative standard errors of the mean between 0.4 鈥 1.6%), which may be further ...
