Accelerated leaching of cementitious materials using ammonium nitrate (6M): influence of test conditions
Abstract : We have focused on the test conditions influence on accelerated degradation of cementitious materials using ammonium nitrate. PH-buffering and renewal of the
leaching solution were studied. PH-buffering appeared not to be very important when the renewal pH remains under eight. Renewal appeared to be the most influential
feature. Its absence leads to calcium accumulation in the leaching solution inducing aggressiveness fall. Degradation is then less marked in terms of depth, flux and
mineralogy. The resulting porosity increase is also smaller.
