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

Figure 5

XRD patterns of clay mineral analysis of unsolidified loess and lime-solidified loess under different curing conditions. (a) Loess solidified with 5% quicklime. (b) Loess solidified with 15% quicklime. (c) Loess solidified with 20% quicklime. (d) Loess solidified with 25% quicklime. Key: I (illite), C (chlorite), I/S (illite + smectite), CAH (calcium aluminate hydrate), CSH (calcium silicate hydrate), and CASH (calcium silicoaluminate hydrate).
