Abstract
This article reports on the study to evaluate the potential possibility of regulating the tricalcium aluminate (C(3)A) hydration process by the addition of calcium sulfite hemihydrate. The kind and the form of hydration products were studied in the system: C(3)A-CaSO3.0.5H(2)O-H2O and C(3)A-CaSO3.0.5H(2)O-Ca(OH)(2)-H2O by use of XRD, DTA and SEWEDS methods as well as the kinetics of hydration along with chemical composition development of the liquid phase. The results thus obtained were compared to the hydration process Of C(3)A with the addition of natural gypsum. The results show that the reaction rate Of C(3)A with the addition of calcium sulfite hemihydrate differs from the analogous hydration process Of C(3)A in the presence of calcium sulfate dihydrate. Also, the kind of hydration products obtained in the presence of CaSO3.0.5H(2)O is different. (C) 2002 Elsevier Science Ltd. All rights reserved.
