Abstract:
Hydrogen evolution in a heavy concrete containing ferro-phosphorus 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 heavyweight slag, otherwise of poten-tial value in heavy concrete.
