Influence of Solid dissolved Al~(3+) ions in Adsorption alkali ability of C-S-H

摘要

The influence of Al~(3+) ions that had been solid dissolved in C-S-H on the amount of Na~+ ions adsorbed 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 electronegative amounts, that is the reason why the adsorption ability of C-S-H for Na~+ ions increase.
