Abstract: The specific properties for nitrogenous organic compounds which will be used for improving engineering properties of expansive clays have been researched by microcosmic analysis technology and geology engineering experiments. The results have shown that the expansibility was inhibited, the cohesive force and the angle of internal friction were increased and the original structure was preserved with a cation exchange and an adsorption of the organic film on the surface of clay corpuscle.
