Curing pre-cast concrete products under high temperature, low relative humidity, and elevated CO2 levels, facilitates the storage of CO2 as CaCO3, thereby transforming the concrete into a carbon sink. To ensure consistent quality of such products, it is essential to ascertain the depth to which CO2 has been stored. This study investigated the feasibility of using Torrent permeameter and Wenner probe as non-destructive testing (NDT) methods to determine the effect of early-age carbonation curing on concrete’s air permeability and electrical surface resistance, respectively, and their variation with respect to carbonation depth. |
