Abstract
Usually, carbonation of concrete causes pH reduction and corrosion of steel, it leads to decrease of durability. However, CaCO3, as results of reaction with hydrates products and CO2, can contribute to improvement of compressive strength. Based on this theory, using carbonation depth, the researches about CO2 absorption of plain concrete and concrete containing CO2 reactive materials has been performed. But, the researches has limitation about using one material, therefore, for this study, considering various CO2 reactive materials, experiment has been proceeded. With water to binder ratio 50%, after initial curing for 2days, accelerated carbonation was performed for 28days, and carbonation depth and compressive strength were measured. As results of carbonation depth, specimen containing desulfurized slag, zeolite showed the highest CO2 absorption, in case of compressive strength, specimens with MgO were indicated as highest compressive strength.
