Experimental Study of the Seepage Deformation of Cement-Soil

Abstract:

Cement-soil is a kind of hydraulic composite building materials which is made by a certain percentage of cement soil particles and water. In order to make a deep research of seepage deformation and the variation law of cement-soil, laboratory test methods were adopted, carrying on deformation tests of indoor penetration on dry density, cement content and age etc, the factors owning outstanding effect on the seepage deformation and failure of cement-soil. The results shows that the seepage deformation and failure appear to change in certain laws with dry density, cement content and age. The gradient of seepage deformation and failure can reach one thousand under the condition that cement percentage is 5%, compaction maximum dry density is standard, and the age is 7 days. And numerical value will be enhanced significantly with the increase of cement content, dry density and the prolong of age. The seepage deformation and failure of cement-soil is not ordinary piping effect or soil-flow failure, but the form of shearing failure. The conclusion has not only a positive exploration significance of the academic research of the seepage deformation and failure of cement-soil, but also a certain practical significance on the geotechnical construction applying cement soil as impermeability.
