The Effect of Powder Detergent Water on Shrinkage Cracks of Soil Due to Drying

Figure 12

Schematic of the interaction process between anionic surfactant and soil: (a) surfactant molecules in the form of monomer can aggregate into micelles and block some of the capillary channels, thereby reducing the amount of evaporation, and (b) surfactant is adsorbed on the surface of soil particles and enhances soil dispersion.
