Estimation of residual shear strength for bentonite-kaolin-Toyoura sand mixture.

Liquefied Residual Strength of Undrained Sand upon A Parametric Approach to Hypo-elastic Model

A parametric study approach evaluating drained/undrained behavior of sand has been developed as a simple/quick hypo-elastic model capable of being used in engineering applications. The volumetric interaction of sand grains behavior against pore water pressure induces the tendency of soil mass volume change to contract/dilate due to variation of effective mean stress on solid grain, pore water p...

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

Unconfined Compressive Strength of Bentonite-Lime-Phosphogypsum Mixture Reinforced with Sisal Fibers

This paper presents the effect of sisal fibers on the unconfined compressive strength of bentonite. The present study is aimed at determining the behavior of bentonite-lime-phosphogypsum reinforced with sisal fibers in a random manner. The sisal fiber content was varied from 0.5 to 2 %. The results indicated that the unconfined compressive strength of bentonite can be increased by the addition ...

Fatal dependence on kaolin and morphine mixture.

A patient is described who had a long history of abuse of kaolin and morphine mixture which ultimately proved fatal.

Determining the unsaturated hydraulic conductivity of a compacted sand-bentonite mixture under constant volume and free-swell conditions

Highly compacted sand-bentonite mixtures are often considered as possible engineered barriers in deep high-level radioactive waste disposals. In-situ, the saturation of these barriers from their initially unsaturated state is a complex hydro-mechanical coupled process in which temperature effects also play a role. The key parameter of this process is the unsaturated hydraulic conductivity of th...
