Zusammenhang zwischen Gewichtsverlust, Festigkeitsabfall und Einlagerungsdauer beim lösenden Ammoniumnitratangriff auf hochfesten Beton / The relation between loss of weight and strength of high strength concrete during the storage in NH4NO3-solution

In this report the behaviour of cementitious materials especially high performance concrete under the attack of ammoniumnitrate solutions is described. From the experimental data concerning the loss of weight and strength of concrete specimens under the chemical attack simple formulas were derived. The formulas enable the estimation of the effect of an chemical attack by solution on cementitious materials. Further within the range of data the duration of experimental programs can be determined in advance.
