Influence of Acidic Substances on Compression Deformation Characteristics of Loess

Figure 2

Compression curve e − log σ of different samples. (a) The acid immersion time is 1 d and the CCC under different acid concentrations. (b) The acid immersion time is 3 d and the CCC under different acid concentrations. (c) The acid immersion time is 6 d and the CCC under different acid concentrations. (d) The acid immersion time is 9 d and the CCC under different acid concentrations. (e) The acid immersion time is 12 d and the CCC under different acid concentrations. (f) The acid concentration is 0 mol/L (distilled water), and the CCC under different acid immersion time. (g) The acid concentration is 0.1 mol/L, and the CCC under different acid immersion time. (h) The acid concentration is 0.5 mol/L, and the CCC under different acid immersion time. (i) The acid concentration is 1.0 mol/L, and the CCC under different acid immersion time. (j) The acid concentration is 2.0 mol/L, and the CCC under different acid immersion time. (k) The acid concentration is 3.0 mol/L, and the CCC under different acid immersion time.
