Cement treatment of soils by liquified stabilization is one of effective methods for improving utilization of large mass of surplus soils generated by construction works. In liquified stabilization, water content of soils is so high comparing with conventional stabilization method that water content affects the strength of cement treated soils. In case of cement treatment in clayey soils, effect of the physical and chemical properties of surplus soils cannot be disregarded too. In this research work, a number of unconfining compression tests have been performed on some cement treated high water content clayey soils. It is shown that effect of water content on the strength of cement treated clayey soils can be evaluated by newly introduced parameter ξ. A method of estimating the strength of cement treated soils using parameter ξ is presented as well.
