PH-buffering and renewal of theleaching solution were studied. PH-buffering appeared not to be very important when the renewal pH remains under eight. Renewal appeared to be the most influentialfeature. Its absence leads to calcium accumulation in the leaching solution inducing aggressiveness fall. Degradation is then less marked in terms of depth, flux andmineralogy. The resulting porosity increase is also smaller. %G English %2 https://cea.hal.science/cea-03293603/document %2 https://cea.hal.science/cea-03293603/file/EJECE%2016%283-4%29%20336-351.pdf %L cea-03293603 %U https://cea.hal.science/cea-03293603 %~ CEA %~ GENIECIVIL %~ DEN %~ CEA-UPSAY %~ UNIV-PARIS-SACLAY %~ CEA-UPSAY-SACLAY %~ DEN-SACLAY %~ ANR %~ GS-ENGINEERING %~ GS-CHIMIE
