Elastic Behavior of Soil-Cement Mixtures

ELASTIC BEHAVIOR For the purpose of defining fundamental concepts and of determining the type of experiments necessary to measure the elastic behavior of soil-cement mixtures, the following general considerations are presented. The elastic behavior of homogeneous isotropic materials is essentially char­ acterized by two coefficients, the modulus

elastic behavior of soil-cement mixtures. the elastic behavior of soil-cement was studied as a function of cement and clay content. soil-cement is considered as quasi-isotropic and homogeneous. synthetic soils were employed for the manufacturing of the test specimens. four different soil types were prepared which were mixed, at their optimum ...

Shear Strength and Elastic Properties of Lime-Soil Mixtures

The modulus of elasticity, E, of the cured lime-soil mixtures ranged from 28, 000 to 160, 000 psi, and the range was from 5, 200 to 8, 600 psi for the natural soils. Longer curing periods for the lime-soil mixtures generally produced an in.crease in E (Fig. 6).

Aug 01, 2018  The laboratory testing results showed that the elastic modulus of the local fine-grained soil-cement mixture has a linear relationship with the UCS. For example, Lee et al. (2005) reported a ratio of E / qu = 145 for slurry-clay-cement mixture, smaller than the lower limit of 175 proposed by Porbaha (1998) and Lorenzo and Bergado (2006).

In FR mixtures, this phenomenon can be attributed to the elastic behavior of fibers, which hinders plastic strain energy by the specimens. On the other hand, CS specimens undergo less plastic strain due to their higher strength and lower ductility, as a result of which they tend to retain their original deformations at the level of loads and ...

The horizontal displacements u(x, y, z) and v(x, y, z) are as- sumed to be zero in the whole mass of soil.
