Experimental Study on the Compressibility of Cement Improved Laterite Soil

In order to improve the mechanical property of the problem soil and satisfy the need of actual engineering construction. Cement-improved soil gradually becomes one kind of common fillings in subgrade construction. Under the soaking or unsoaking conditions, the natural soil and improved cement-soil with different compaction degree, study the compressibility of the Laterite soil in somewhere in Hunan. And also analyze its change rule of compressibility. It shows that the compression deformation of improved cement-soil reduce significantly when compared with natural soil sample; at the same condition, the larger compaction degree is, the smaller deformation of soil sample will be; and the deformation of the soaked soil sample will be larger than the unsoaking ones.
