The purpose of this study is to investigate applicability of CO2 curing to cement product with admixture like fly ash(FA) and Blast furnace slag(BS). The test for CO2 uptake rate, color change by phenolphthalein indicator and compressive strength were executed. As a result, CO2 uptake rate was 5.9¡7.73% and specimen with BS showed low CO2 uptake revel. Color change by phenolphthalein indicator showed carbonation of CO2 cured specimens. The compressive strength of CO2 cured specimens was about 40 times higher at early age and 4 times higher at 3 days than that of normal air cured specimens. Then the specimens with BS showed higher compressive strength. |
