A master's thesis in the College of Engineering discussed the topic: "Long-Term Soaking Effect on the CBR and Durability of Highway Clayey Subgrade Soil Treated with Geopolymer."The thesis, presented by Israa Ibrahim Farman, aimed to study the effect of long-term soaking and repeated wetting and drying cycles on the bearing capacity and durability of clayey subgrade soils used as road foundation layers. It also aimed to evaluate the stabilization efficiency of finely ground blast furnace slag (GGBFS)-based geopolymer in improving the properties of this soil under harsh wet conditions.
