  The long term acid neutralizing capacity of steel slag

  2000 4 1 The determination of acid neutralizing capacity of the electric arc steel slag depends on the reaction time A short time titration experiment may lead to a large underestimate of the ANC particularly at low pH About 500 h experiment may be needed to account for about 95 of the ANC for the most interesting pH range.
