Study on the Mechanism of Stabilizing Loess with Lime: Analysis of Mineral and Microstructure Evolution

X-ray diffraction (XRD) technique was adopted to test the mineral composition of quicklime-solidified loess with different lime-adding rates at curing periods. Scanning electron microscopy (SEM) and nitrogen adsorption were used analyze microporous structure solidified loess. The unconfined compressive strength limit moisture content combined evolution mechanism microstructure change period clarify results showed reduced clay minerals decrease in number large pores due increase hydrates pozzolanic products during extended period. soil fabric transformed from a compact into mesh composing acicular crystal cementation. main reasons for liquid plastic limits lime-solidified after are substance microstructure.
