Monitoring chloride concentrations in hardened cement pastes using ion selective electrodes
In a previous paper it has been shown that silver/silver chloride ion selective electrodes are stable in a simulated pore solution and that the potential of these electrodes is a function of chloride ion activity. This has now been compared with chloride concentrations in the pore water, found using pressure extraction technique, with chlorides added as sodium chloride to the mix water in concentrations ranging from 0.046 Mdm-3 to 0.46 Mdm-3 to ordinary portland cement pastes with a water cement ratio of 0.45. The results show good correlation between concentration added and activity calculated from electromotive force data, with a activity coefficient of 0.46+/-0.07, which agrees with values calculated in the previous paper.
