초록

This laboratory study showed the performance evaluations of a improved C12A7 based mineral accelerator (I-CA) by both mortar and shotcrete tests. Performance of I-CA as a shotcrete accelerator was excellent by KCI-SC-102, which is a Korean specifications of shotcrete accelerator. In addition, I-CA showed equal qualities to the setting time and the compressive strength when compared those of the existing C12A7 based mineral accelerator (CA). The I-CA was manufactured with 40wt.% of electric arc furnace reducing slag, 24wt.% of lime, and 36wt.% of bauxite, indicating that the commercialization of I-CA contributed to recycle electric arc furnace reducing slag and to reduce the manufacturing cost of C12A7 based mineral accelerator due to the use a cheap raw material(electric arc furnace reducing slag), and to reduce the greenhouse gas emission due to the reductions in usage of lime and bauxite.
