In this study, a wet carbonation method targeting high carbonation rate was developed to prepare aragonite whisker using fine recycled concrete waste (FRCW), aiming to effectively capture CO2 and convert FRCW into high-value products. The effect of operational factors, including MgCl2 concentration,...
