| Summary | We found concrete building absorbs ~5 kg CO2/m2 during its service life. Type of surface coating and property of attached air (temperature, humidity and CO2 concentration) are important factor on CO2 uptake. In addition, recycled base course material, a major use of recycled concrete, absorbs ~9 kg CO2/ton. Recycled concrete aggregate absorbs more CO2 than base course material. |
