STRENGTH AND EROSION OF LIME STABILIZED GYPSEOUS SOIL UNDER DIFFERENT FLOW CONDITIONS

Abstract

AbstractThis work aims to study the effect of erosion on the strength, loss in weight and gypsum dissolution of gypseous soil stabilized with (4%) lime, take into account the following variables: initial water content, water temperature, soaking duration or flow duration and water velocity. The results indicate that, the unconfined compressive strength decreased for samples soaked in water have low temperature (50 and 250 C), further decrease in strength with increasing soaking duration. The higher water temperatures (490 and 600 C) showed increasing in the unconfined compressive strength. High water velocity causes decreasing in unconfined compressive strength, more loss in weight and more loss in gypsum content, for all values of flow duration and water temperature.
