English term or phrase:site saturation
The Avrami exponent n has been defined more exactly in terms of three additional constants (Brown et al. 1985):
n = (P/S) + Q.
Q is a constant that indicates the nucleation rate: Q = 1 for a constant nucleation rate, and Q = 0 for nucleation site saturation (zero nucleation rate).
Consequently, Q = 1.15 for the sample without gypsum and Q = 0 for the sample with gypsum addition.
Therefore, all nucleation sites were saturated and tobermorite crystallized without further formation of nuclei in the system having high sulfate ion concentration.
