Abstract

In order to study the type of soil stabilizers suitable for coarse-grained soils and their curing mechanism, a total of 12 sets of mixing ratios were designed in this paper. The unconfined compressive strength, water stabilization properties, and SEM tests were carried out, respectively. The test results show that the stabilization of coarse-grained soil according to the recommended dosage of the three curing agents does not meet the standards for the use of highway subgrade. However, additional cement and gravel dosages can be made to be applied in highway projects. One type of inorganic curing agent is more suitable for stabilizing gravel soils than the other two. Under the action of the curing agent, C-S-H and AFt have been transformed into Ca(OH)2 and AFm, making the microstructure denser and forming a complete and solid curing whole. The macroscopic performance shows that the specimen has good strength and water stability.
