Research on the Compaction Characteristics of Cement-Stabilized Soil Under Different Compaction Energies
Year: 2025
Type: article
Abstract: In geotechnical engineering, when the natural soil fails to meet the requirements of engineering projects, the soil is often treated by means of compaction and chemical stabilization. China is the world’s largest producer and consumer of cement, making the use of cement highly cost-effective. A large number of studies on cement-stabilized soil have proven that it has good engineering properties. When using cement stabilization to reinforce soil, compaction is often combined to achieve better results. This paper directly proposes that changes in compaction energy will affect the optimum moisture content (OMC) and maximum dry density (MDD) of cement-stabilized soil. From the perspective of changes in cement content and compaction energy, three levels of compaction energy and five levels of cement content are set to systematically analyze the variation trends of liquid limit, plastic limit, and compaction characteristics of stabilized soil under the combined action of cement stabilization and traditional compaction. The results show that with the increase in the cement content, the modified soil exhibits plasticity over a wide range of moisture content due to an increased liquid limit. When the cement content is high, and the compaction energies is low, the soil shows an uncompacted state. This state will decrease significantly with the increase in compaction energy. Both the OMC and the MDD change with the variation of the compaction energies and the cement content.
