Life cycle CO2 assessment of concrete by compressive strength on construction site in Korea

As research on the reduction in the life cycle carbon dioxide (LCCO2) emissions of buildings has become increasingly important, the development of technologies that can quantitatively assess the LCCO2 emissions of a building at the level of the construction materials is essential. In addition, concrete of various compositions, such as high-performance concrete mixed with fly ash and blast furnace slag and eco-concrete, has become readily available and thus, a quantitative evaluation of CO2 basic units for these new materials is needed. However, basic units for various types of concrete are not provided by the National Life Cycle Inventory Database (LCI DB) in Korea. Therefore, thorough research on these materials has become an important priority.
