Effect of EN-1 Soil Stabilizer on Soil Shear Strength
[Objective] To investigate the solidifying capability of soil stabilizer EN-1 on loess soil.[Methods] Direct shear experiments with 4 loessial soils of Lou soil,sand soil,loessal soil and yellow brown soil,with different solidifying agent content and curing age are conducted.[Results] EN-1 can improve the shear strength of the four types of soil,especially the cohesion of soil in Yangling District and Ankang City.[Conclusion] The amount of EN-1 needs to be appropriate,as excessive amount of EN-1 may reduce the shear strength of soil.The optimal amount of EN-1 is 0.01%,and the optimal curing age is 28 d.Soil stabilizer EN-1 is more suitable for soil with high clay content,rather than soil with high sand content.
