Abstract
This paper presented a study on wet and dry durability of solidified silt, by using zeolite and cement for solidification. The wet and dry test was conducted to measure the changes of mass, volume and unconfined compression strength (UCS) with different zeolite and cement content. Furthermore, the influence of zeolite and cement on the physical and mechanical properties of solidified silt will be discussed. The results show that cement plays an important role in improving the wet and dry durability of solidified silt. The volume of solidified silt is slightly expansible with the addition of zeolite at low cement content, but the expandability can be substantially offset as the cement content increase to 20%. With the change of cement content, the addition of zeolite has different effects on the wet and dry cycle durability of solidified silt: zeolite can weaken the wet and dry cycle durability of solidified body when the cement content is less than 20%, while zeolite can enhance the wet and dry cycle durability of solidified body when the cement content is more than 20%.
