thaumasite

🗣️

DEFINITION

a rare mineral containing calcium silicon carbonate sulfate hydroxide, a sulfate bearing mineral that damages concrete

EXAMPLE SENTENCES

Geologists identified thaumasite in the deteriorated concrete samples collected from the old bridge. Thaumasite forms when sulfate ions react with calcium silicate hydrate in cement under cold conditions. The presence of thaumasite indicates a specific form of sulfate attack that weakens concrete structures. Researchers developed new methods to detect thaumasite before it causes significant structural damage. Thaumasite was first discovered in metamorphic rocks in Sweden during the nineteenth century.
