Analysis of Mechanical Properties of Loess with Cement Incorporation Ratio

Taking loess as the research object, influence of cement content on mechanical properties was studied. Firstly, basic physical parameters were obtained through laboratory index test, and improved by using Portland cement. Secondly, under different incorporation ratios (3%, 5%, 7%, 9%), heavy compaction test liquid-plastic limit carried out respectively to obtain cement-improved loess. Finally, shear strength compressive soil samples are unconsolidation undrained triaxial unconfined test. The results show that liquid limit, plastic adding increase compared with original sample, indicating binding force between particles is plasticity enhanced. variation range dry density water has no obvious relationship At same time, compressibility reduced collapsibility eliminated. With age, cement-modified also increases. Through unconsolidated tests tests, significantly after cement, soil-cement increased content, stability obviously improved.
