Prediction on CO 2 uptake of recycled aggregate concrete

Abstract. Carbonation of concrete is a process which absorbs carbon dioxide (CO 2).Recycled aggregate concrete (RAC) may own greater potential in CO 2 uptake due to the faster carbonation rate than natural aggregate concrete (NAC). A quantitative model was employed to predict the CO 2 uptake of RAC in this study. The carbonation of RAC and the specific surface area of recycled coarse ...
