Abstract: A large number of saline soil is distributed in the extremely arid desert area, causing great harm to the construction of the traffic trunk line. Based on the super chlorine saline soil, using water glass as curing agent, its strength, moisture absorption and weatherability were analyzed. The study found that the higher the concentration of water glass, the closer the microstructure of the solidified superchloride saline soil, and the corresponding increase in compressive and anti-folding strength.When the contentration of water glass solution was 16% and the content in saline soil was 18%,the compressive strength of the cured specimen could be above 1 MPa.However, due to the failure of the Si—O—Al bond in water, the waterproof performance was poor, the compressive and anti-folding strength of the Si—O—Al bond was lower. After the test piece was dehydrated, the strength could be restored. After 30 days of natural environment, the quality of solidified superchloride saline soil was lost, but its compressive and anti-folding strength increased obviously, and the weatherability could be superior.
