Testing of industrial products - Aggregates for construction

Many aggregates have acid-soluble sulfate contents well below the specification limit of 0.2%, and many slags have acid-soluble sulfate contents below their specification limit of 1.0%. For such materials, poor reproducibility of the determination of acid-soluble sulfate is not a problem. Thus if an aggregate has a true acid-soluble sulfate content less than 0.1% it is unlikely that a ...

The results of the experiments show that the reproducibility of the test is not good enough for it to be used as the reference method for the determination of the acid-sulfate content of aggregates. This is when the determinations are to be used to check that the aggregate complies with a specification limit around 0.2% to 1% SO 3.
