Summary:The authors are developing mechanically-compacting flowable concrete with low CO2 emission for rationalization, labor reduction in concrete work, and reduction of CO2 emissions. In this paper, as a case study on the application of developed concrete, a concrete mix and a combination of reinforcement materials that satisfy the design criteria strength and specified durability have been set, and their application in terms of productivity, economy, and environmental impact has been estimated. The desired improvement in productivity and reduction in CO2 emissions could be achieved, and the construction costs required to achieve these goals were generally understood. The CO2 price in CO2 emissions trading was calculated for each case, and it was shown that the CO2 price depends on the CO2 reduction measure.
