Abstract The stabilization by lime or Portland cement has long been the most commonly used methods for clay soil. But it wart the purpose of this reserch to define the effectiveness malt content on unconfined compressive strength of limeflay mixture and cementrlay mixture. From result of a laboratary investigation, saInt content in sample soil was not concernd with variation of PH value. PH value of lime 10% mixture and of cement 10% mixture were near 12.4, 11.6 respectively. In case of more than 7 curing days, PH value and Ca++ion concentration were decreased with increasing curing time. Also the result of X-ray difflection analysib for stabilized soil by admixture 10% in 90 curing days showed that the diffrection intensity of Tobermorite and Ettringite and other reaction products was smaller in the case of addition of salt 8% than malt 0% in stabilized soil. When lime-soil mixture and cement-boil mixture were cured in 2$0^{circ}C$ and 5$^{circ}C$, 2$0^{circ}C$ cured mizture produced significantly higher compressive strength than 5t cured mixture and air dry curing sample produced higher than cured sample in water. The addition of salt 2~4% in conjuntion with lime or cement may accelerate strenth gain or not prevent front However, the addition of salt 8% prevent from strength gams.
