Abstract: Some basic properties of cement stabilized soil are discussed on the basis of a lot of laboratory tests.The compressive strength of cement stabilized soil depends mainly on cement dosage and secondly on moisture content of intact soil.Based tests of 28 prescriptions,a simple expirical relation is given.It is also concluded that the lowest cement dosage should be provided for any soft intact soil,or the stabilization is invalid at all.A simple relation that the compressive strength of cement stabilized soil is inversely proportional to the square of the moisture content of soil is given,and the other influence factors on cement stabilized soil are discussed in brief too.Moreover,other engineering properties such as deformation,seepage and initial shear strength of cement stabilized soil are discussed in this paper.
