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

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).

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 ...

When compared to the mixture without curing stress, the elastic moduli of the mixtures were increased by as much as 100% to 1000% when the mixture was cured under vertical confining stress. Strength gain with curing time is modeled by using data from 6 individual studies that provide 23 sets of data.
