EFFECTS OF SURFACE-ACTIVE AGENGT ON MECHANICAL BEHEVIORS OF LOESS
The surface-active agent is common in the environment and its effect on the engineering properties of soil remains unclear up to date. The surface-active agent, Sodium DodecylBenzene Sulphonate was found able to cause obvious changes in mechanical behaviors of Chinese loess. The shear strength behavior decreased in the SDBS-polluted loess. The effect of the pollutants on the shear strength of loess is found to be similar to that of moistening, and the influence of pollutants gets more and more weak with increasing the degree of saturation. The microstructure was investigated to explain the experimental observations. It is proposed that the presence of SDBS in loess and other soils should be tested and the relevant influences should be evaluated in engineering practices in the future.
