With the application of new solidifying agent to ground engineering
the influence of solidifying agent on the strength of solidified clay is widely noticed. The variation of unconfined compressive strength of the clay improved with solidifying agent #Ι with different mixing ratios and ages are studied through the laboratory experiment. The data of unconfined compressive strength show that the stabilizing effect of the agent #I Ιis superior to that of cement.A prediction equation is developed for calculating the strength of stabilized clay by analyzing the experimental data.
