【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。更多还原

【Abstract】 The influence of Al³⁺ 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 Al³⁺ 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 CS-H for Na⁺ ions increases.更多还原
