Study on the Application of Curing Agent in Coastal Silt Solidified Soil
There is a large amount of silt in the soil of coastal cities.In order to reduce the pollution of silt to the urban environment and solve the shortage of building materials in the process of engineering construction,it is of great environmental and economic value to carry out the study of solidified soil.Taking the coastal silt excavated from the east extension of Jinliwen Expressway in Wenzhou Longwan District as the research object,new binder with different dosages were added to improve its mechanical properties and deformation stability.The unconfined compressive strength index,CBR value and expansion rate of solidified soil were compared and analyzed with compaction degree(92%,96%,100%)and dosage(5%,6%,8%,10%).The results show that the unconfined compressive strength and CBR value of the coastal silt solidified soil increase with the increase of the dosage of curing agent and the degree of compaction,and the increase amplitude decreases gradually.The dosage of 8%is more significant for strength improvement and the maintenance of deformation stability.
