REACTIONS OF AGGREGATES INVOLVING SOLUBILITY, OXIDATION, SULFATES, OR SULFIDES

THIS REPORT COVERS AVAILABLE INFORMATION ON REACTIONS INVOLVING SOLUBILITY OR OXIDATION OF AGGREGATES WHILE THEY ARE ENCLOSED IN CONCRETE AND REACTIONS INVOLVING RELEASE OF SULFATES OR SULFIDES FROM AGGREGATES ENCLOSED IN CONCRETE. EXPERIENCE INDICATES THAT THESE PHENOMENA MAY CREATE LOCAL PROBLEMS THAT USUALLY TAKE THE FORM OF UNSIGHTLY CONDITIONS ON CONCRETE CONSTRUCTION, SUCH AS STAINING OR SPORADIC SPALLING AND POP-OUT FORMATION. RELIABLE METHODS FOR DETECTING DELETERIOUSLY REACTIVE FORMS OFFERROUS SULFIDES IN MINERAL AGGREGATES WOULD BE A WORTHWHILE ADDITION TO TESTING PROCEDURES IN AREAS WHERE THESE MINERALS HAVE BEEN FOUND TO BE OF SIGNIFICANCE IN THE PERFORMANCE OF CONCRETE. /AUTHOR/
