Abstract

Abstract

At same cement content, strength difference between stabilized soil samples prepared from different soil samples with similar physical characteristics obviously. Pore solution were squeezed from the stabilized soil samples with various cement contents, concentration of ions in the solution and strength of the stabilized soil samples were measured. The result shows that due to soil absorbing of Ca( OH) 2, the concentration of Ca( OH) 2in the pore solution may not reach to saturation, in turn the CSH gel generated by cement hydration may decrease; the higher the amount of Ca( OH)2absorbedby soil, the less CSH gel generated by same dosage of cement, so the poorer the strength of the stabilized soil sample. The influence of various chemical characteristics of soil on the strength of the stabilized soil is boiled down to the influence on the concentration of Ca( OH) 2in the pore solution. The strength of stabilized soil samples made from different soil samples with similar physical characteristics are almost the same when the concentration of Ca( OH) 22in the pore solution reach to saturation.
