  • In this study, the carbonation characteristics of concrete according to the mixture of OLED waste glass were evaluated. Replacement capacities of OLED waste glass were 0%, 10%, 20%, and 30% of cement, and they were named OG 0, OG 10, OG 20, and OG 30. As a result of the compressive strength test, OG 0 without replacing OLED waste glass showed high intensity until the 14th. However, the higher the replacement rate of OLED waste glass, the higher the compressive strength of 28 days. In addition, the speed of carbonation was faster with the higher the replacement rate of OLED waste glass, and the accelerated carbonation experiment was about three times faster than the natural carbonation test. In conclusion, the carbonation characteristics of OLED concrete are expected to be positive in terms of atmospheric CO2 absorption.
