- Abstract:
-
In order to improve the properties of stabilized soil which can make full use of local soil and water resources,the effect of new nano soil-stabilizer on the mechanical properties of reconsolidated loessial soil was studied through typical laboratory mechanical tests. The results indicate that:(1)the unconfined compressive strength of stabilized soil shows the exponential function with the content of nano soil stabilizer;(2)the unconfined compressive strength of nano stabilized soil can be improved by about 10%~30% compared with ordinary stabilized soil and grade 32.5 cement soil;(3)it was found that the microstructure and mechanical properties of the nano stabilized soil were more superior by comparing the relationship between water absorption,dry density,particle size and compressive strength of three different stabilized soils. Using nano soil stabilizer can significantly improve the physical and mechanical properties of loessial soil,which has a broad engineering application prospect in the Loess Plateau and other areas lacking sand and rock.
