Although ettringite and thaumasite differ in formal symmetry, the transition
between them could in theory be achieved continuously: in practice solid solution
appears to be incomplete; ettringite and thaumasite solid solutions coexist.
Moreover ...

Durability of Concrete and Cement Composites
What is serious about thaumasite sulfate attack is that the main binding
constituent of hardened cement, C-S-H, becomes converted into thaumasite,
which is a non-binding powdery material having no inherent compressive
strength. The key ...

The heavier fraction, though less in volume, was composed of the greenish-
yellow (chalcedony-yellow) mineral which, when examined under the
microscope was found to be monticellite, and the white "float" or light material
was thaumasite.

The fissuring occurred later than the contact metamorphism of the limestone, and
the filling of the fissures with thaumasite of course occurred at a still later period.
