When some oxygen ions penetrate concrete, calcium nitrite reacts with oxygen to be transformed into calcium nitrate. However, when all the calcium nitrite added during the mixing has been transformed into calcium nitrate, oxygen ions resume their attack on the reinforcing steel. Therefore, the addit...
