Critical salt concentrations of particle release caused by different cations

With horizontal seepage experiments,this paper analyzes the critical salt concentrations（CSC）of the different cations,by examining such solutions as NaCl,KCl,LiCl,NH4Cl,CaCl2 and MgCl2,which can cause the particle release of water sensitivity of porous media.The research results show that the critical salt concentration is not a single value,but is a range;the critical salt concentrations of monovalent cation solutions of Na+,K+,Li+ and NH4+ are 0.06±0...
