Sulfate attack in concrete - Understanding Cement

Sulfate attack in concrete and mortar. Sulfate attack can be 'external' or 'internal'. External: due to penetration of sulfates in solution, in groundwater for example, into the concrete from outside. Internal: due to a soluble source being incorporated into the concrete at the time of mixing, gypsum in the aggregate, for example. External sulfate attack ...
