Abstract

Tricalcium silicate (C3S), the major phase of Ordinary Portland Cement (OPC), occurs in several polymorphic forms depending on the amounts and types of impurity ions present. The hydration products of triclinic, trigonal and monoclinic C3S samples have been studied for a comparison with the silicate hydration products of OPC, using TEM and SEM. In the early stages, less than one day, there are distinct differences observed between the products on the surfaces of grains of different crystal structure but later all three appear similar. This suggests a common mechanism of hydration at later times, irrespective of structure, but the influence of the foreign ions in the first few hours is significant.
