Unconfined compressive strength of clay soils at different temperatures: Experimental and constitutive study

Unconfined compressive strength (S_u) is one of the soil engineering parameters used in geotechnical designs. Due to the temperature changes caused by some human activities, it is important to study the changes in S_u at different temperatures. On the other hand, due to the differences in the mineralogical composition of...

Cation Exchange in the Presence of Oil in Porous Media

Cation exchange is an interfacial process during which cations on a clay surface are replaced by other cations. This study investigates the effect of oil type and composition on cation exchange on rock surfaces, relevant for a variety of oil-recovery processes. We perform experiments in which brine with a different composition than that of the...
