Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...

Abstract The time-dependent behavior of three gypseous soils was investigated. had gypsum content 66%, 44%, and 14.8%. mineralogical chemical properties the were determined. Two series tests performed. In first, collapsibility characteristics investigated for a long period (60 days) by conducting single double oedometer tests. second series, effect relative density on collapse with time samples...

Abstract In order to meet environmental and socio-economic challenges, the recycling of waste be used in treatment geotechnical problems is one main ways preserving environment with a lower economic value. The objective this experimental work improve characteristics study mechanical behaviour collapsible soil treated new hydraulic stabilizer composed Crushed Granulated Blast Furnace Slag (CGBS)...

An aluminous montmorillonite has been synthesized at hydrothermal conditions (623 K, 120 MPa) and compared to the natural Na-exchanged Wyoming montmorillonite (Na-SWy2). The synthetic product is characterized by a high cation exchange capacity (83 meq/100g) and ethylene glycol specific surface area (764 m 2 /g) similar to Na-SWy2 but with a higher purity with one crystalline phase. Compacted sm...

Currently, inconclusive evidence characterizes the thermally induced deformation of sands. In this context, role transient nature heat diffusion on sands has remained largely disregarded. This paper presents a theoretical and computational investigation dynamics characterizing under oedometric conditions. The study shows that heating rates determined by pore fluid pressure dissipation timescale...
