Concrete is exposed to sulfates in two ways, externally sourced and internally sourced. Most commonly, sulfate attack occurs where concrete is exposed to high sulfate content in the soil, in areas of run-off, and in wastewater. Secondly, Portland cement contains a small percentage of gypsum (calcium sulfate dihydrate). The sulfate in the Portland cement is an internal source, and is activated when the internal temperature of the curing concrete reaches 160 degrees Fahrenheit, a condition which can and should be avoided.
