Abstract

 Steel slag-dredged soil mixture is a material used for landfill and shallow field construction. As a result of calculating the CO2 emissions during the construction of the steel slag-dredged soil mixture, the CO2 emissions during backhoe mixing were reduced by about 40% by using the Calcia bucket.

 In addition, CO2 emissions during construction were reduced by 30% or more compared to backhoe mixing by using a drop mixing vessel and putting it into water through a tremie pipe.
