The present study investigates the material and hydration properties of nPOFA mixed cement mortar with early carbonation curing based on the fact that each process contributes to fill capillary pores, to enhance compressive strength and to reduce CO2. Mortar samples were carried out compressive strength test, phenolphthalein test, MIP testt and SEM. Pulverized cement paste was analytically characterized by XRD, TG/DTA, and FTIR analzes. The fabricated specimens were cured for 0,7, and 28 days in the carbonation chamber which set to carbon dioxide concentration of 5%

Palm Oil Fuel Ash(POFA), Agricultural by-product, has been studied in especially ASEAN countries. However studies about effects of superplasticizers on early compressive strength of concrete with POFA are insufficient. Therefore, in this study, the effects of superplasticizers were evaluated in terms of compressive strength.
