Sulphate content of aggregate crushing samples

No analyzed standard samples containing both sulfate and sulfide were avail able for direct evaluation of this method. A sulfate standard was prepared of gypsum and barite (each ground to pass a 100-rnesh sieve) mixed in the ratio 3:1. This was carefully analyzed for sulfate content
