| 英文摘要 | Among various strategies for CO2 mineralization, the carbonation of recycled concrete aggregate (RCA) has emerged as a highly promising approach. Atmospheric carbonation of RCA during storage on recycling platforms offers a low-cost solution, although it is a time-intensive process. Despite its potential, there is a notable lack of standardized test methods to evaluate the CO2 binding capacity and carbonation rate of RCA. This study introduces a novel test method, termed the Instantaneous Binding Rate (IBR) method, which measures the instantaneous CO2 binding rate of an RCA sample placed in a closed cell over a short duration. The binding rate is periodically measured over several weeks, and the total quantity of CO2 bound is calculated by integrating the time-dependent binding rate. The IBR method is validated using crushed mortar samples under natural carbonation conditions and is compared with conventional methods, including thermogravimetric analysis (TGA) and loss on ignition (LOI). A strong correlation is observed between the results of the three methods. Notably, both LOI and IBR methods enable the testing of larger RCA sample masses, overcoming the limitations of the TGA method. Furthermore, the IBR method reveals the significant impact of moisture conditions on the CO2 uptake of RCA, highlighting its utility in understanding RCA carbonation behavior. |
