摘　　要：研究了A l3+离子的固溶对C-S-H表面吸附Na+离子量的影响。实验结果表明,A l3+离子固溶于C-S-H结构中将使C-S-H表面所带的负电量增大,因而也就增大了C-S-H表面对Na+离子的吸附能力。The influence of Al^3＋ ions that had been solid dissolved in C - S - H on the amount of Na^＋ ions absorbed on C - S - H surface was studied. The experimental results show that the solid dissolution of Al^3＋ ions in C - S - H structure makes the electronegative C - S - H surface increase of electronegative amounts. That is the reason why the absorption ability of C - S - H for Na^＋ ions increases.
