Abstract: In recent years, reduction target of CO2 emission is declared in many countries. CO2 emission and industrial waste are controversial issues in concrete-related industries because of large amount emission. Conventional admixtures of concrete, such as furnace blast slag and fly ash, are by-products from the industries other than concrete industries, which significantly motivate to utilize for the low responsibility to their embodied CO2 emission as well as high contribution to improving mechanical properties of concrete in reducing cement consumption, However, many researchers have mentioned the difficulties to evaluate quantitative effects for reducing CO2 emission using admixtures because of including CO2 emission in transportation. In this paper, reduction of CO2 emission introducing admixtures in large quantity at Kanto region in Japan is quantitatively evaluated using "ecoMA" a kind of resource flow simulator. As a simulation result of ecoma, it was quantitatively observed that CO2 emission is restrained through the replacement of admixture. At the case of furnace blast slag and fly ash, 3 million tons, and 0.55 million tons of CO2 are cut down respectively.
