The effect of water content on the carbonation process in cement paste under intermediate (60%) and high (90%) relative humidity (RH) conditions was clarified through water content distribution along the penetration depth. Results reveal that the inhibition of carbonation, due to the water plug effect, occurs at a specific water content level, regardless of whether the RH condition is intermediate (60%) or high (90%). A decreased carbonation degree at the carbonation front over the carbonation duration can be explained by the varying penetration lengths of carbon dioxide. |
