Abstract |
This study was conducted with the purpose of reducing the carbon dioxide emissions of portland cement by utilizing high performance clinker cement (HPCC). The amount of carbon dioxide emitted when manufacturing HPCC was calculated, and the change in carbon dioxide emissions according to the change in the mixing ratio of cement was analyzed. In addition, HPCC-based concrete with the same mix proportions as Ordinary Portland Cement (OPC)-based concrete was manufactured and their properties were compared. As a result of the study, it was found that non-carbonate materials should be included at a weight ratio of approximately 13% in order for the carbon dioxide emissions of HPCC to be equivalent to those of conventional blended cement. The strength development performance of HPCC-based concrete was found to be similar to that of OPC-based concrete.
