This paper contains the results of calcium removal study from the composition of concrete by the action of ammonium compounds, causing corrosion and weakening their durability. Modelling in laboratory conditions of this process indicates the destructive and aggressive action of the solution with -1000 mg/dm3 NH4 + (ammonium sulphate), stress concentration on concrete components. |
