Durability of CAC and CAP containing simulated secondary wastes was studied via leaching test. A significant effect of curing temperature was observed in CAP when concentrated effluent was incorporated. After leaching test, hemi- and mono-carbonate phases were formed CAC, whereas CAP did not indicate any obvious change in the product phases.
