21. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders
Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER
22. Suffusion of Glacial Till Dam Cores : An Experimental Investigation
Sammanfattning : Suffusion, also called internal instability, is an internal erosion mechanism that occurs in embankment dams when fine-grained particles are washed out of the core soil matrix by seepage. Initiation of internal erosion depends mainly on three major factors: grain size distribution of the soil, stress conditions and hydraulic load; whilst its continuation depends of the filter properties.

23. Thaw Mechanism in Subgrades
Sammanfattning : Freezing-thawing, changes the properties of soil due to the phase change of the water in the soil body. Freezing-thawing cycles in the soil have been studied for several decades including extensive laboratory research. In this study, the main focus is thawing based on laboratory investigation. LÄS MER
24. Mechanical properties of excavated sulfur rich soil stabilized with cement - A laboratory and field experiment
Sammanfattning : Sulfide soils are silty soils, often found in saturated conditions, under the groundwater level. Characteristics of these soils, including particle size distribution and consistency limits along with chemical composition and environmental properties, cause excavation to be necessary for construction purposes.
