The chemistry of pore fluids is directly related to the nature of the binder, to its content in soluble alkali oxides and to the water/binder ratio. Experimental data has mainly been obtained with pure pastes or mortars and measured contents of OH-ions were between 0. 2 and 0. 8 M under these conditions, corresponding to pHs of around 12. 8 to 13. 7. The main cations are Na+ and K+, in equivalent amounts :[Na+] + [K+]=[OH-] This is why the first member(alkali cations) is often confused-sometimes incorrectly-with the second(alkalis or OH-ions). 1, record 2, English, - alkali%20cation

[...] Les cations principaux sont Na+ et K+, de sorte que le bilan ionique simplifié s'écrit : [Na+] + [K+] = [OH-] C'est pourquoi le premier membre (les alcalins) est souvent assimilé - et quelquefois abusivement - au deuxième (les alcalis). 1, record 2, French, - alcalin
