Step Chronology Date Type Process Changes
#1 during layer formation 2011-04-22 layer formation slightly compressed grains dispersed agglomerate of grains placed in the cell under ambient temperature and air. Manual compression
#2 after sample formation 2011-04-22 chemical kept 10 min under ambient temperature and air (H2O and CO2) The carbonation process started during and after sample preparation under ambiant air. Slight reaction of CO2 with Portlandite
#3 on parent sample 2011-04-22 thermal cooling of the sample to 0°C adsorption of water and condensation of ice on the minerals
