ABSTRACT
The geo-polymerization process for the improvement of soft soils has gotten significant attention in the recent past. In the field, the natural moisture condition varies, and it is difficult to remove the moisture. The role of the presence of moisture in soils on the geo-polymerization process is not well studied. The alkali activators were mixed with the sample having initial moisture. The compaction characteristics of marine clay with water and alkali activators as pore fluid were conducted. Further, unconfined compressive strength (UCS) tests were conducted on marine clay with natural moisture conditions and addition of various alkali activators. The UCS tests were conducted for various curing periods. The compaction results showed an increase in maximum dry density and decrease in optimal alkali liquid content. Further, the UCS results showed a decrease in shear strength at lower curing periods. However, it showed significant improvement in shear strength at higher curing periods.
