Accurately evaluating the clay particle content is of great significance to discriminating the seismic liquefaction by static sounding test or standard penetrating test.

Silicone; Penetrating agent; Concrete; Radical polymerization; Hydrolytic polycondensation; Orthogonal design; Infrared spectrum; Gel permeation chromatography; Performance test; Chloride ion.

According to the test results, a mathematical model was established to predict the OBC consumption of the sludge barrier under AMD penetrating conditions.
