The lime stabilization tests were performed to investigate the effects of treat ting on the physico-chemical and strength characteristics of Onomichi clay subjected to lime addition. The trace of treatment effects were made clarify by X-ray diffraction, unconfined compression, consistency test, and etc. The main results obtained are as follows; (1) The increase in strength of the clay for the lime stabilization treatments is attributed to the permanent cementing action between soil particles of the new crystalline minerals which are formed in consequence of the chemical reaction of the lime and activated Al_2O_3 and SiO_2 in the soil; (2) CaCO_3 has been little effect with regard to increments of the strength; (3) It was found that the optimum mixed ratio have been related to the consistency; (4) Unconfined compression test make used of a.index of the treatment effects; (5) A change of integrated intensity for montmorillonite obtained by the X-ray diffraction test could relate ions exchange with pozzolanic reaction.
