Study on Strength Forming Process of Cement Stabilized Soil
Series of indoor tests were done to study the strength forming process of soft soil stabilized by cement. Dry cement was used to consolidate soft soil through modeling the field construction situation, and the stabilized soil samples in different curing days were studied by means of direct-shear test, grading analysis test and scanning electronic microscopy. So the parameters of shearing strength, granularmetric compostion and microstructure feature of treated soil in each curing stage were determined. Results shown that, at the early stage, there was a slow increase in the strength of cement-soil, and with the curing days increasing, the mechanical property, component and microstructure feature of samples were improved obviously.
