Case Study on the Effect of Mechanically-compacting Flowable Concrete with Low CO₂ Emission on Productivity, Economic Efficiency, and Environmental Impact

抄録

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.
