Thaumasite Sulfate Attack in Cement Mortars Exposed to

conventional sulfate attack. The presence of chloride in solution led to further enhancement of sulfate resistance of fly ash mortars, probably due to the positive effect of high chloride binding capacity. However, it enhanced lime leaching in GGBS mortar which would provide more calcium ions required for gypsum precipitation.

Studying thaumasite sulfate attack using compressive

Thaumasite sulfate attack (TSA) is known as a very aggressive deterioration process in concrete structures, which can destroy the calcium silicate hydrate (C–S–H) matrix, disintegrate concrete, and diminish the strength at its ultimate stages. Practically, this kind of sulfate attack is the most severe deterioration mechanism of its kind .
