Pyrite in Aggregate. By Concrete Construction Staff. Is the presence of pyrite in an aggregate likely to be injurious to concrete? The presence of an appreciable amount of pyrite (iron disulphide) is undesirable, since this compound readily decomposes into weak products such as iron sulphate and limonite, along with the formation of sulfuric acid.
