Research on the Properties of Collapsible Loess Reinforced by Cement


Article Preview

The collapsibility of loess ground can directly affect the stability of the subgrade. Therefore, How to adopt practical technical measures to reduce or eliminate its collapse deformation is an important content in foundation design in collapsible loess zone. Taking collapsible loess of the Liaoning Fuxin to Chaoyang highway as an example, the dispensing formula tests of cement were done. Mix cement in varying proportions with loess of different water content, then unconfined compression strengths of samples at four different ages were tested, and the relationship between improved soil strength and content of quick lime as well as ages was analyzed. The results indicate: 1) When the ages are certain, the strength of loess increases along with the mixture ratio increases, when the cement mixture ratio between 4%-14%, the scope of increases is quite obvious; 2) When the mixture ratio of specimens is certain, the intensity of test specimens increases along with the stadium increases, the intensity grows obviously in 28 days, and the growth rate is small in 28 to 90 days, the intensity will tend to be steady in the stadium of 90 days.
