Presented results show that introduction of already 25%
of Portland cement into calcium aluminate cement may
change physical and chemical processes. During first
minutes of hydration of cement paste containing 25% of
Portland cement, the heat evolution is more intensive than
in the case of sample with only 5% of this additive as well
as of reference sample. It may be an effect of release of
SO4
2- ions to solution and then formation of ettringite.
Moreover Ca2? ions coming from Portland cement take
part in forming of hydrated aluminate phases. As a result
the induction period decreases. However, mechanism
consisting in acceleration of hydration of both cements
should be also taken into consideration, e.g. acceleration
the hydration processes of Portland cement as the result of
heat released by reacting aluminate cement [6].
