Description

<p>This paper presents an overall picture of ecological concrete and discusses technologies that achieve both the i-Construction goal of labor saving at construction sites and the reduction of CO2 emissions through the use of ecological concrete. By combining the technology of admixing calcium carbonate powder produced with CO2 as a component of self-compacting concrete, which contributes to labor saving in compaction work, and the technology of applying CO2-absorbent concrete to stay-in-place formwork, it is possible to simultaneously achieve labor saving and CO2 reduction. Furthermore, such technology is expected to reduce the cost of stay-in-place formwork, and the possibility that it may yield considerable shortening of the construction period along with the reduction of CO2 emissions at a cost comparable to current cost is discussed.</p>
