HYDROGEN EVOLUTION FROM FERROPHOSPHOROUS AGGREGATE IN PORTLAND CEMENT CONCRETE

HYDROGEN EVOLUTION IN A HEAVY CONCRETE CONTAINING FERROPHOSPHORUS AGGREGATE WAS NOTED DURING CONSTRUCTION OF A BIOLOGICAL SHIELD FOR A NUCLEAR GENERATING STATION. WHILE THE REACTION WAS OF A SELF-LIMITING NATURE, THE CONCRETE WOULD PRODUCE OVER 25 TIMES ITS VOLUME OF HYDROGEN BEFORE THE REACTION CEASED. THE FACTORS AFFECTING THE REACTION AND THE POSSIBLE MECHANISMS INVOLVED ARE DISCUSSED. SUBSEQUENT INVESTIGATION HAS SHOWN THAT A SIMILAR REACTION OCCURS WITH FERROSILICON, ANOTHER HEAVY-WEIGHT SLAG, OTHERWISE OF POTENTIAL VALUE IN HEAVY CONCRETE. /AUTHOR/
