In this process, finely divided gypsum is added to a solution of ammonium carbonate causing calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution: N H 4 2 C O 3 + CaSO 4 → N H 4 2 SO 4 + CaCO 3. After formation of the ammonium sulfate solution, manufacturing operations of each process are similar.

 · Abstract. The standards ASTM 1012 (2013) and NBR 13583 (2014) report the procedure for the evaluation of concrete subjected to sulfate attacks. However, the standards were based on sodium sulfate studies. This paper demonstrates that the methods suggested by the aforementioned standards may not be applicable to external attacks of ammonium sulfate.
