Step Chronology Date Type Process Changes #1 during layer formation 2011-05-18 layer formation slightly compressed grains dispersed agglomerate of grains placed in the cell under ambient temperature and air. Manual compression #2 after sample formation 2011-05-18 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
