A flotation-based approach to the quantification of pyrrhotite in concrete aggregates
Pyrrhotite-bearing aggregates are a major cause of internal sulphate attack (ISA) in concrete. The concentration of pyrrhotite is usually too low to permit direct accurate quantification. Hence, safety restrictions put on aggregates are expressed in terms of the total sulphur content. This paper out...
