Synthetic preparation of thaumasite – several possible routes for thaumasite formation
is connected to formation of AFt phases – thaumasite and ettringite that cause serious damage to cement stone. Thaumasite (CaSiO3·CaCO3·CaSO4·15H2O) is less known and less are built into thaumasite unite cell, therefore, c...

Synthetic preparation of thaumasite – several possible routes for thaumasite formation
Presented work is a part of an experiment where limestone is partially replaced by fluidized fly ash during cement manufacturing. Hydration of this type of cement is connected to formation of AFt phases – thaumasite and ettringite that cause...
