Abstract
The combined effect of lignosulfonate and sodium carbonate on the hydration of C 3A and C 3ANa 2O solid solution was examined by DTG and TG curves, by XRD analysis and by zeta potential measurements. It is confirmed that the simultaneous addition of lignosulfonate and carbonate completely blocks the C 3A hydration with an induction period whose length is proportional to the percentage of admixtures. On the other hand, no induction period was observed in the hydration of C 3ANa 2O solid solution in the presence of both lignosulfonate and carbonate. The effect of the admixtures on the zeta potential is substantially the same for C 3A and C 3ANa 2O solid solution. The liquefying effect of NC and lgs combined addition seems to be more pronounced on C 3A than on C 3ANa 2O solid solution.
