Abstract
This research determines the carbonation resistance of concrete containing micro and nano palm oil fuel ash (POFA) using accelerate carbonation testing. Microstructures were studied using XRF, XRD and SEM. Workability and sorptivity rate were also tested. The results show that 10% micro POFA with 0.5% nano POFA had the highest carbonation resistance. Further increasing the amount of POFA would decrease the carbonation resistance of concrete.
