Impact of carbonation on moisture penetration and mineralogical profile in cement paste when moisture and CO2 penetration from one direction was studied under four different RH (23-80%) and T (20 and 40℃) conditions. Results showed increasing RH promotes the carbonation degree of CH while limiting the carbonation process by water blockage. High temperature was found to promote carbonation and moisture penetration though not to the same extent. The opposite effects of carbonation on water penetration were discussed by comparing the distance between carbonation and moisture penetration depths.
