Permissible Levels of Chlorides and Sulfates in Aggregate ...

01.02.1996  0.1% for aggregates. in reinforced concrete. 3. maximum value=0.4%. Reader Response: Your answer regarding permissible levels of chlorides and sulfates in aggregate might be OK for Saudi Arabia but certainly not for most of the United States. A limit on NaCl is meaningless: Does one measure sodium, or chloride, or both? Don't other chlorides count?

Sulfate in concrete

Excessive amounts of mobile sulfate, derived from aggregates or other constituents in concrete, can cause disruption due to expansion. BS 8110 part 1 Structural use of concrete, 1985, had a limit of 4% by mass of cement based on the total acid soluble sulfate method expressed as SO 3 (clauses 6.2.5.3). This restriction was dropped in the 1997 edition as materials were deferred to BS 5328 ...

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 laboratory will report a result in
