An attempt was made to improve the strength characteristics of shirasu against the slope failure. Cement was mixed with shirasu in small amounts of 1%, 1.5% and 2%, and cured at constant temperature of 20℃ for a period of 96 hours. The results of this study indicate that the axial strength and shear strength of shirasu increased noticeably by using cement in small amounts. Slaking test was also performed, the result of which has shown that cement is working well as bonding and water-proof agent.
