notably contribute to the problem of sulfate attack, which causes cracking and deterioration of concrete. Some aggregates can contain these sulfates and so can contribute to a reduction in durability. However, there is currently no standard test methodology to determine the sulfate content in the aggregates used to produce Portland cement concrete.
